checkboxes and deselection

There seems to be a problem with checkboxes (i.e. xforms:select) - if you select one or more checkboxes and then change your mind and try to deselect them you have to leave at least one selected. If you try to deselect them all it just ignores you.

I thought this must be someting I am doing wrong in my application but I can see exactly the same problem demonstrated in the "Sortable Tables" example on the Orbean community website. Try deselecting all the checkboxes in the example - it won't let you. I agree that in this example it might be desirable behaviour, but it should be possible to have a set of checkboxes where none are selected.

Is there something I am missing? An attribute on xforms:select perhaps?

RE: checkboxes and deselection

Julian,
Sounds like a problem, tried it on the examples and it allows you to
deselect, but when clicking submit it ignores your request. What engine are
you using (NG or classic), How are you using the xforms:select in your
application?

RE: checkboxes and deselection

In reply to this post by julian.fawcett

In the demo application my guess is that it is by design (and I think
that's not using NG).

However it seems related to an outstanding bug that I'm still getting
(see thread "RE: [ops-users] Bug with xforms:select1 and xforms:select
(3.0 beta 4 nightly)") -- I'm finding that if an instance is updated,
and there are checkboxes bound to this instance, when the instance is
resubmitted checkbox state isn't correctly reflected in the instance
document.

No, it should just work, and it does with the online examples:

http://www.orbeon.com/ops/goto-example/xforms-controls

Can you provide OPS version, XForms engine type (Classic or NG), and if
possible a reproducible case?

Re: Re: checkboxes and deselection

I am using v3.0Beta and am using the Classic engine (not sure how to go about using the NG engine).

It is interesting that, as you say, it works on the http://www.orbeon.com/ops/goto-example/xforms-controls example, but not on the http://www.orbeon.com/ops/goto-example/xforms-report example.

So I guess the question is what is the difference between the two.

Having looked at the source code I notice that the xforms-controls example which does work uses <xforms:itemset/> whereas the xforms-report example which doesn't work is using <xform:choices/> with embedded <xforms:item/>s.

My application also uses <xform:choices/> like this:

<xforms:select ref="method" appearance="full">
<xforms:choices>
<xforms:item>
<xforms:label>Telephone</xforms:label>
<xforms:value>Telephone</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Fax</xforms:label>
<xforms:value>Fax</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Social Services Visit</xforms:label>
<xforms:value>SocialServicesVisit</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Letter</xforms:label>
<xforms:value>Letter</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>E-mail</xforms:label>
<xforms:value>Email</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Meeting or Discussion</xforms:label>
<xforms:value>MeetingOrDiscussion</xforms:value>
</xforms:item>
</xforms:choices>
</xforms:select>

Re: checkboxes and deselection

Administrator

Julian,

The "Sortable Table" example (which is quite outdated BTW and should be
upgraded to XForms NG) does this on purpose, as noted: when the user
deselects all the checkboxes, then upon submission the original XForms
instance is reloaded so as to select again all the checkboxes.

The "XForms Controls" example uses XForms NG and has a completely
different architecture.

The best thing you can do is to build a case that we can reproduce.

Re: Re: checkboxes and deselection

Erik,

Thanks for your time on this. I have put together a simple test application with just a single page to demonstrate the problem.

The page-flow.xml looks like this:

<config xmlns="http://www.orbeon.com/oxf/controller" xmlns:xi="http://www.w3.org/2003/XInclude" xmlns:xu="http://www.xmldb.org/xupdate"
instance-passing="forward" xmlns:oxf="http://www.orbeon.com/oxf/processors" xmlns:xxforms="http://orbeon.org/oxf/xml/xforms">

<files path-info="*.css"/>
<files path-info="*.js"/>
<files path-info="*.gif"/>
<files path-info="*.jpg"/>
<page id="checkboxes" path-info="/checkboxes" xforms="oxf:/form.xml" model="oxf:/checkboxes.xpl" view="oxf:/view.xpl">
<action when="/form/action = 'save'">
<result page="checkboxes">
<xu:update select="/form/test">
<xu:copy-of select="document('oxf:instance')/form/test/*"/>
</xu:update>
</result>
</action>
</page>
<page id="layout-css" path-info="/oxf-theme/orbeon-layout.cssd"
model="/oxf-theme/orbeon-layout.xpl"/>
<epilogue url="oxf:/config/epilogue.xpl"/>
</config>

The xforms file (form.xml) looks like this:

<xforms:model xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xi="http://www.w3.org/2003/XInclude">
<xforms:submission method="post"/>
<xforms:instance>
<form>
<test>
<check/>
</test>
<action/>
</form>
</xforms:instance>
</xforms:model>

The view file (view.xpl) looks like this:

<p:config xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:p="http://www.orbeon.com/oxf/pipeline"
xmlns:oxf="http://www.orbeon.com/oxf/processors" xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms">
<p:param name="instance" type="input"/>
<p:param name="data" type="input"/>
<p:param name="data" type="output"/>
<p:processor name="oxf:identity">
<p:input name="data">
<xhtml:head>
<xhtml:title>Test Application</xhtml:title>
<xhtml:meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
</xhtml:head>
</p:input>
<p:output name="head" id="head"/>
</p:processor>
<p:processor name="oxf:identity">
<p:input name="data">
<xhtml:p>Testing Checkbox</xhtml:p>
</p:input>
<p:output name="textone" id="textone"/>
</p:processor>
<p:processor name="oxf:identity">
<p:input name="data" href="aggregate( 'xhtml:body', #textone, #data )"/>
<p:output name="data" id="stuff"/>
</p:processor>
<p:processor name="oxf:identity">
<p:input name="data" href="aggregate( 'xhtml:html', #head, #stuff )"/>
<p:output name="data" ref="data"/>
</p:processor>
</p:config>

Finally, the model file (checkboxes.xpl) looks like this:

<p:config xmlns:xforms="http://www.w3.org/2002/xforms" xmlns:p="http://www.orbeon.com/oxf/pipeline" xmlns:oxf="http://www.orbeon.com/oxf/processors" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:xxforms="http://orbeon.org/oxf/xml/xforms">
<p:param name="instance" type="input"/>
<p:param name="data" type="output"/>
<p:processor name="oxf:identity">
<p:input name="data">
<xforms:group ref="/form">
<xforms:group ref="test">
<xforms:select ref="check" appearance="full">
<xforms:choices>
<xforms:item>
<xforms:label>Telephone</xforms:label>
<xforms:value>Telephone</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Fax</xforms:label>
<xforms:value>Fax</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Letter</xforms:label>
<xforms:value>Letter</xforms:value>
</xforms:item>
<xforms:item>
<xforms:label>Email</xforms:label>
<xforms:value>Email</xforms:value>
</xforms:item>
</xforms:choices>
</xforms:select>
</xforms:group>
<xforms:submit>
<xforms:label>Save</xforms:label>
<xforms:hint>Save form</xforms:hint>
<xforms:setvalue ref="action">save</xforms:setvalue>
</xforms:submit>
</xforms:group>
</p:input>
<p:output name="data" ref="data"/>
</p:processor>
</p:config>

With this application I can select checkboxes and click the Save button and when the page refreshes it always shows a true representation of my selection with the one problematic exception: if I have deselected all the checkboxes it appears to do nothing, so when the pages refreshes any checkboxes that were previously selected remain selected.

Julian

Re: checkboxes and deselection

Julian,

I managed to reproduce this problem, and I entered a bug:

http://forge.objectweb.org/tracker/index.php?func=detail&aid=304625&group_id=168&atid=350207

I was unable to fix the bug right away, otherwise I would have done so.
Unfortunately I cannot guarantee when this will be fixed, since this is
with XForms Classic.
