Hello, I'm trying to support a situation where a group of controls (or
a single control) appear only if another node in the same instance
document does not appear. When I was using XForms extension for
Firefox in the past, I was able to do it this way:
<xforms:group ref="current()[not(AbsentElement)]">
<xforms:trigger>
<xforms:label>Add Skilled response
section</xforms:label>
.. action to add AbsentElement to context..
</xforms:trigger>
</xforms:group>
The general idea is to only show a trigger if AbsentElement is not a
child of the current context, which will add that element if clicked.
However, I get the following exception
XSLTForms Exception
--------------------------
Error parsing the following XPath expression :
current()[not(AbsentElement)]
Unknown operator at '[not(AbsentElement)]' in 'current()[not(AbsentElement)]'
Can this be done in XSLTForms?
Thanks.
