call-xpl() error - prefix xxforms has not been declared

Hank, thank you for your reply, however, xxforms is declared in the relevant location in my XPL file e.g. XSLT stylesheet, XPL config element.

The error message mentions oxf:/ops/xforms/xforms-server.xpl  - is this relevant, or would it help to identify the source of the problem?

thank you
Tanya

Subject: [ops-users] Re: call-xpl() error - prefix xxforms has not been declared

Hi Tanya,

As with any namespace, it must be declared in scope:

xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"

see:

http://wiki.orbeon.com/forms/doc/developer-guide/xml-namespaces

Cheers,
Hank

2011/7/28 Tanya Gray <[hidden email]<mailto:[hidden email]>>

Hello

I would like to use the xxforms:call-xpl() function as described on the Orbeon website:
http://wiki.orbeon.com/forms/how-to/logic/execute-xslt-from-xforms

The XForms below  that includes the call-xpl() function generates an error stating that the prefix xxforms has not been declared.

code:
 <xforms:trigger>
                      <xforms:label>Display input form fields</xforms:label>
                      <xforms:action xmlns:ev="http://www.w3.org/2001/xml-events" ev:event="DOMActivate">
                          <xforms:insert nodeset="instance('instance-report')//MIIDI/researchObject[index('MIIDIresearchObject')]" origin="xxforms:call-xpl('choice-replace.xpl', 'instance', instance('instance-report'), 'data')"/>
                      </xforms:action>
                  </xforms:trigger>
error:

XPath syntax error at char 88 in {...port'), 'data') xmlns:xxfor...}:
Prefix xxforms has not been declared
Resource URL    Line    Column  Description     XML Element
oxf:/ops/xforms/xforms-server.xpl       55      65
reading processor output
name → response
id → xforms-response
      <p:output name="response" id="xforms-response"/>

I would just like to ask if my use of call-xpl is correct, and if so, why the error might occur.

thank you for any help with this
Tanya
