Link two selects

Hi,

I have a repeat table and inside each row I have two xforms:select1.
What I would like is to link the two selects in order when the first select changes, the list of selectables values of the second select changes.
Below I paste my example that has a select1 for countries and a select1 for cities. So when the country changes the list of selectable cities should change accordingly.

Does anybody know if this is possible and how can I implement this. I've looked at the examples but didn't find any solution.

************This is my instance(countries):

<countries>
<country>
<name>Spain</name>
<id>0</id>
<cities>
<city>
<name>Barcelona</name>
<id>0</id>
</ city >
<city>
<name>Madrid</name>
<id>1</id>
</ city >
</ cities >
</ country >
<country>
<name>France</name>
<id>0</id>
<cities>
<city>
<name>Paris</name>
<id>0</id>
</ city >
<city>
<name>Toulouse</name>
<id>1</id>
</ city >
</ cities >
</ country >
</ countries >

************This is my xforms inside the repeat:

<xhtml:tr>
<xhtml:td class="estilo1">Country</xhtml:td>
<xhtml:td align="right">
<xforms:select1 appearance="minimal" ref=" @selcountry">
<xforms:itemset nodeset="instance(countries)/country">
<xforms:label ref="name"></xforms:label>
<xforms:value ref="id"></xforms:value>
</xforms:itemset>
</xforms:select1>
</xhtml:td>
</xhtml:tr>
<xhtml:tr>
<xhtml:td class="estilo1">City</xhtml:td>
<xhtml:td align="right">
<xforms:select1 appearance="minimal" ref="@selcity">
<xforms:itemset nodeset=" instance(countries)/country [index(i)]/cities/city ">
<xforms:label ref="name"></xforms:label>
<xforms:value ref="id"></xforms:value>
</xforms:itemset>
</xforms:select1>
</xhtml:td>
</xhtml:tr>

Thanks in advance,
Jordi

Re: Link two selects

There seems to often be several potential solutions to a problem. For this particular one, I do not think I would use any repeat statements, but instead rely on the itemset node in the select1 element.

Here is my approach:
1. Use the itemset attribute on the select1 element to get the list of values
2. Once a value has been selected in the first box, copy the associated values for the second select box to a new instance/location
3. Have the second select1 box list values from this new instance/location

This is just form the top of my head, so its probably not 100% correct. But it should show you what I mean :-)

instance="first-select-box-instance"
<first>
    <first-select-box>
            <value/>
            <value/>
            <value/>
                ...
    </first-select-box>
    <second-select-box>
        <selected-value/>
        <allowed>
            <value/>
            <value/>
            <value/>
                ...

        </allowed>
    </second-select-box>
</first>

instance="main-instance"
<main>
    <first-select-box>
        <value/>
        <second-select-box>
            <value/>
            <value/>
            <value/>
                ...
            </values>
        </second-select-box>
    </first-select-box>

    <first-select-box>
        <value/>
        <second-select-box>
            <values>
                <value/>
                <value/>
                <value/>
                ...
            </values>
        </second-select-box>
    </first-select-box>

    ...
</main>

...

    <xforms:select1 ref="instance('first-select-box-instance')/first-select-box/value" id="repeat-1">
        <xforms:itemset nodeset="instance('main-instance')first-select-box/value">
            <xforms:label ref="value"/>
            <xforms:value ref="value"/>
        </xforms:itemset>
      <xforms:action ev:event="DOMActivate">
            <xforms:setvalue ref="instance('first-select-box-instance'')/second-select-box/allowed"
                                      value="'instance('main-instance')/first-select-box[index('repeat-1')]/second-select-box/allowed"
   </xforms:action>
    </xforms:select1>

    <xforms:select1 ref="instance('first-select-box-instance')/first-select-box/second-select-box/selected-value" id="repeat-2">
        <xforms:itemset nodeset="instance('first-select-box-instance')/first-select-box/values">
            <xforms:label ref="value"/>
            <xforms:value ref="value"/>
        </xforms:itemset>
    </xforms:select1>

Hope this helps!

Re: Link two selects

Or, a different approach:

<xforms:instance id="selection">
    <selection>
        <contry/>
        <city/>
    </selection>
</xforms:instance>

<xforms:instance id="countries">
    <countries>
        <country selected="true()">
            <name>Norway</name>
            <selected>true</selected> 
            <city>oslo</city>
            <city>bergen</city>
            <city>trondheim</city>
        </country>

        <country selected="false()">
            <name>Sweden</name>
            <selected>false</selected>
            <city>Goteborg</city>
            <city>Stockholm</city>
        </country>

        <country selected="false()">
            <name>France</name>
            <selected>false</selected>
            <city>Paris</city>
            <city>Niece</city>
        </country>
    </countries>
</xforms:instance>
...

    <xforms:select1 ref="instance('selection')/country" id="select-country">
        <xforms:itemset nodeset="instance('countries')/country" id="countries-itemset">
            <xforms:label ref="name"/>
            <xforms:value ref="name"/>
        </xforms:itemset>
        <xforms:action ev:event="DOMActivate">
            <xforms:setvalue ref="instance('countries')/country/selected[.=true]">false</xforms:setvalue> 
            <xforms:setvalue ref="instance('countries')/country[index('countries-itemset')]/selected">true</xforms:setvalue>
       </xforms:action>
    </xforms:select1>

    <xforms:select1 ref="instance('selection')/city" id="select-city">
        <xforms:itemset nodeset="instance('countries')/country/selected[.=true]/city">
            <xforms:label ref="."/>
            <xforms:value ref="."/>
        </xforms:itemset>
    </xforms:select1>
...

Haven't tried this out, but hopefully its good for some inspiration!

Hope that helps.

There seems to often be several potential solutions to a problem. For this particular one, I do not think I would use any repeat statements, but instead rely on the itemset node in the select1 element.

Here is my approach:
1. Use the itemset attribute on the select1 element to get the list of values
2. Once a value has been selected in the first box, copy the associated values for the second select box to a new instance/location
3. Have the second select1 box list values from this new instance/location

This is just form the top of my head, so its probably not 100% correct. But it should show you what I mean :-)

RE: Link two selects

Thanks Henrik for your ideas that helped me to understand better xforms.

Now I am able to have two selects linked, but what I need is to have a table of selects linked.

I attach my xsl code, as you will see when you change one of the selects in the first column it changes the selectable values of all the selects in the seconds columns.

The problem is in this expression:

<xforms:itemset nodeset="instance('groups')/group[id = (instance('selects')/tabsel[index('i_event')]/selA)]/subgroups/subgroup">

I don’t know why it doesn’t work.

Re: Link two selects

Jordi,

I am struggling with an similar sort of problem myself. If I can work
it out, I'll be sure to email this list. In the meantime, I would
suggest you break the complex xpath expression into its constituent
parts, and try to output using xforms:output. That should tell you
what part of the expression is not returning the correct value:

<xforms:itemset nodeset="instance('groups')/group[id =
(instance('selects')/tabsel[index('i_event')]/selA)]/subgroups/subgroup">

could become:

<xforms:output ref="instance('groups')/group/id"/>
<xforms:output ref="instance('selects')/tabsel[index('i_event')]/selA)"/>
<xforms:output ref="index('i_event')"/>

What's the result of this? Also, could you send a working example of
the code (just mock up the data if you need to), attached to the
email? That would help me analyze the problem .

I will also email this list with my particular problem (and the
solution when I find it) - Perhaps this will prove helpfulll to you,
too :-)

Re: Link two selects

Jordi,

when debugging xforms, you might find it helpfull to uncomment these
lines in resources/config/log4j.xml:

<category name="org.orbeon.oxf.xforms.processor.XFormsServer">
<priority value="debug"/>
</category>

to enable more logging in tomcat.

RE: Link two selects

Henrik,

I have output the xpath expressions but still don't know the cause. This is
the code (only 1 xsl) to reproduce the problem.

Re: Link two selects

Jordi,

could you attach the file instead of copy-pasting into email body? It
screws up the indentation and adds silly line breaks everywhere.

Thanks!

Re: Link two selects

In reply to this post by Henrik Pettersen

Ah, yes. I finally got it to work!

I have attached the code in case anyone is interested:

My problem was that I wanted a select action to copy a small xml fragment to a new instance, and not just a single value ( i.e. <xforms:value ref="aspic:id"/> was not sufficient).

So inside my select:

<xforms:select1 ref="aspic:knowledgebase/aspic:id" appearance="minimal" id="select-knowledgebase">
    <xforms:itemset nodeset="instance('initial')/aspic:knowledgebase">
        <xforms:label ref="aspic:name"/>
        <xforms:value ref="aspic:id"/>
    </xforms:itemset>
    ...... {action goes here} .....
</xforms:select1>

I added an action to copy each element of this xml fragment to my new instance:

<xforms:action ev:event="xforms-value-changed">
    <xforms:setvalue ref=     "instance('selection')/aspic:selection[index('queries-repeat')]/
                                   aspic:knowledgebase/aspic:name"
              value="instance('initial')/aspic:knowledgebase[aspic:id=
                                         instance('selection')/aspic:selection[index('queries-repeat')]/
                                         aspic:knowledgebase/aspic:id]/aspic:name"/>
....
</xforms:action>

Notice the very long xpath expressions!

Check out the code for more in-depth details (it's self-contained and runnable).

Hope this helps, Jordi!

RE: Link two selects

Hi Henrik, good you finally resolved your problem.

I also solved my problem thanks to your suggestions for debugging xforms.

The point was to use xxforms:repeat-current('i_event')/selA to get the current row selection.

I attached the complete working code with several rows of linked selects.

I haven’t used <xforms:action ev:event="xforms-value-changed"> but is good to know for the future

Best regards,

Jordi

Re: Link two selects

Excellent!

Yes, xxforms:context('repeat-id') and element[index('repeat-id')] should be interchangable, with the prior being a much more terse (and perhaps favorable) syntax.

It can also be usefull to pay attention to all the events that are generated when you load and interact with a page: Look out for triggering of these events in the debug output (That's where I found xforms-value-changed).
