Select1 + Value + Concat

Hi all,

Lets say I have a:

Request instance:

<a>

</b>

Test instance:

<test>

<y>

</y>

</test>

And I want something like this:

<xforms:select1 ref="instance('request_instance')/target" appearance="full">

<xforms:item>

<xforms:label ref="instance('request_instance')/name"/>

<xforms:value ref="??"/>

</xforms:item>

</xforms:select1>

I want the value of the radio button to be all the values of z separated by a ‘,’. For example “blah2, blah3”. I wasn’t too sure how this could be done as there isn’t that much XPath functions, can anyone help?

Thanks,

RE: Select1 + Value + Concat

Naman,

I think the XPath function you would want to use woudl be string-join() ...... something like this ...

string-join(instance('test_instance')//z, ',')

RE: Select1 + Value + Concat

Hi Steve,

Thanks for your reply. I tried what you suggested and I got:

“XForms error: A reference to a node (such as text, element, or attribute) is required in a binding. Attempted to bind to the invalid item type: class java.lang.String”

But I was thinking, wouldn’t it be a little more complicated then just doing a // to concatenate ALL the z elements with z as a separator?

RE: Select1 + Value + Concat

Naman,

You get that error because the ref attribute for the item will need to be bound to a node, not an xpath expression .... one way to do this would be to make another instance with a node in it and store the result of the string-join in there. I believe the string-join should work for you unless there is something I'm missing here .... I don't think concat() will work for you since you have a sequence that you want separated by commas ..

you could try something like this in your model ...

<xforms:instance id="temp">

<joined-z/>

</temp>

</xforms:instance>

<xforms:bind nodeset="instance('temp')/joined-z" calculate="string-join(instance('test_instance')//z, ',')"/>

and then in your view ...

<xforms:select1 ref="instance('request_instance')/target" appearance="full">

<xforms:item>

<xforms:label ref="instance('request_instance')/name"/>

<xforms:value ref="instance('temp')/joined-z"/>

</xforms:item>

</xforms:select1>

HTH.

Like Steve said, if you use <xforms:value ref="..."/>, the XPath
expression needs to return a node. So you can't use string-join().
However, you can do <xforms:value value="..."/>. With the value
attribute, returning a string is OK.
