How to Render the Controls Dynamically??

Hi All,

This is my Model

<xforms:model>
<xforms:instance id="control types">
    <controlTypes>
          <textBox/>
          <radio/>
    </controlTypes>
</xforms:instance>

<xforms:instance id="control types">
    <controlCode>
          <textBoxCode> <xforms:input ref="instance('controlTypes')/textBox"/></textBoxCode>
          <radioCode><xforms:select1 ref="instance('controlTypes')/radio"/></radioCode>
    </controlCode>
</xforms:instance>
<xforms:model>

In body i am trying to get the controls dynamically by calling like this

<xforms:output ref="instance('controlCode)/textBoxCode"/>
<xforms:output ref="instance('controlCode)/radioCode"/>

But always i am getting the output as shown below in

<xforms:input ref="instance('controlTypes')/textBox"/>
<xforms:select1 ref="instance('controlTypes')/radio"/>

THANKS & REGARDS

hi sathish,

you can use:

<xforms:group ref=".[<condition>]">
[content conditionally shown depending on the evaluation of <condition>]
</xforms:group>

So, to dynamically switch between two controls, you've got to insert
both of them, each in a xforms:group that references the condition that
tells which control to show.

That's right: you can't dynamically introduce new controls into an
XForms document, at least this way. You could possibly do this as a
pre-processing step in XSLT, for example, but that's a completely
different matter.

Florian's approach below is the one we have been using in many cases.
