You should use either one of them</SPAN><BR /><SPAN>- I don't see where the form property variable is set as input to the web service. I see a variable of PROC_DATA and an id of IMP1, but these are not used in the input spec of the web service.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN></BODY></HTML> Wed, 09 May 2012 09:10:07 GMT https://connect.hyland.com/t5/alfresco-archive/process-variable-and-webservice/m-p/102135#M71029 trademak 2012-05-09T09:10:07Z
