Is there anyway to have the ref in a setvalue be dynamic?

Hi Folks,

A normal setvalue looks something like:

<xforms:setvalue ref="instance('some-instance')" value="..."/>

The value being set is a static definition. Is there anyway to have the reference be dynamic? In other words, could the name of the instance to be set be stored in another instance and referred to indirectly?

Any help most welcome!

Thanks,

Mike Paschal

this should be possible - take a look at the xxforms:evaluate [1] or
the xxforms:evaluate-avt() [2] functions.

It's an XPath expression so it's already pretty dynamic.Try:

<xforms:setvalue ref="instance(instance('foobar')/instance-name)" value="..."/>
