How to parametrize src instance attribute?

would like to make the src attribute dependant on an input instance tag value, how can I do that in an xhtml file:

for example this:

<xforms:instance id="instancia-respuestas-basfi" src="/exist/rest/db/orbeon/xforms-ehistoria/usuario1/respuestas_basfi.xml"/>

being dependant of login user....

if tried xsl-copy with doc('input:instance') expressions but with no success....

thx a lot

rich

Richard,

You cannot use xsl directly with xforms in a xhtml file.
You can send a submission to retrieve the file based on the user at the start of the page with : <xforms:action ev:event="xforms-ready">
In many places you can use AVT but I don't know if it's possible with xforms:instance tag and src attribute.
Try this :

<xforms:instance id="instancia-respuestas-basfi" src="/exist/rest/db/orbeon/xforms-ehistoria/{instance('user')/username}/respuestas_basfi.xml"/>

TIA

Marc

In fact, you can...see for example this:

        <!-- Form-specific model -->
        <xsl:copy-of select="doc(concat('../forms/', doc('input:instance')/*/form-id, '/model.xml'))/*"/>
        <!-- Model to handle persistence -->
        <xi:include href="oxf:/apps/forms/common/persistence-model.xml" xxi:omit-xml-base="true"/>
        <!-- Model to handle resources -->
        <xi:include href="oxf:/apps/forms/common/resources-model.xml" xxi:omit-xml-base="true"/>

 in /apps/forms/detail/detail-view.xhtml

is not possible, expression with braces throws orbeon exception.

is it possible to use AVT in order to parametrize id's of xforms ui controls, for example fix different id's for loop generated select1's?

thx

Right, this won't work, because AVTs in XForms require that all XForms  
instances have been initialized.

However, if you use XSLT, then you will be able to use AVTs and the  
doc('input:instance') function.

Or, as already suggested, you can use a submission upon xforms-ready  
to populate the instance dynamically. At Orbeon, we often do this:

   <xforms:instance id="parameters-instance" src="input:instance"/>

Then upon xforms-ready you can use the contents of this parameters  
instance to perform a submission which will load the correct data.

By "loop-generated", do you mean produced by xforms:repeat?  
xforms:repeat will automatically assign different ids to the resulting  
HTML controls, so you don't have to do anything special.
