I've a problem with xform, that see only a customer system administrator. And i cannot see in my computer. There is a xforms code, where output has a ref-attribute ("if(licence) ..")
<xforms:group ref="content">
<xforms:label>The shop list</xforms:label>
<xforms:output ref="name"><xforms:label>Name</xforms:label></xforms:output>
<!--There is a complex expression-->
<xforms:output
ref="if(licence) then
if(licence/to) then
concat(licence/code,' (',
concat(substring(licence/from,9,2),'.',substring(licence/from,6,2),'.',substring(licence/from,1,4))
,' - ',
concat(substring(licence/to,9,2),'.',substring(licence/to,6,2),'.',substring(licence/to,1,4))
,')')
else
concat(licence/code,' (no due date, from ',
concat(substring(licence/from,9,2),'.',substring(licence/from,6,2),'.',substring(licence/from,1,4))
,')')
else
'You have not a licence!'">
<xforms:label>licence</xforms:label>
</xforms:output>
</xforms:group>
And the admin can see the next mistake in his log, that coming so much.

To anybody help me, how to repair this problem? Thank you
As the error states, the problem is that the expression in your <xforms:output ref="..."> element, evaluates to a string not a node.
The ref attribute on an xforms control needs to a refer to a node within the data model, not to a string.
