Pipeline input not connected exception

Hi,

I have 2 instance variables in an xform that I want to pass into a xpl file to be processed there. Is this possible?

If it is possible could someone please help me with the correct syntax?

Here is an example of what I am trying to do...

Please note I have altered the below to simplify the example, and that param1 and param2 NEED to be separate instances, as param2 is feedback from another submission to a webservice.

Whenever I run this example I get a Exception...

 Exception at line 8, column 46 of oxf:/apps/ofbiz/simple-workflow.xpl
org.orbeon.oxf.common.ValidationException: line 8, column 46 of oxf:/apps/ofbiz/simple-workflow.xpl: Pipeline input "param1" is not connected
oxf:/apps/ofbiz/simple-workflow.xpl, line 8, column 46: Pipeline input "param1" is not connected


Any help would be very much appreciated

Regards

Mark

Hi,

I have manage to get around this issue...  by making a new model instance which has param1 and param2 as elements of param3... what I did to get param2 to be updated from the web service was to add actions on the submit-done event to update my param3... it seems to work well enough....

If anyone wants more info please let me know..

Regards

Mark
