Hello -



I think if you look further down the stack trace you sent you will see that this error is actually coming from the EmailRecieverService class -> is this true?



Assuming this is true, it looks like it could simply be something incorrect in the settings you have put in your QPac. What kind of variables are you trying to set with this XDP data which has been recieved by the EmailReciever QPac?



If you provide some details here it may help. Also Howard may chime in with some suggestions.

This is a known bug, happens because of wrong version of dom4j.jar.This has been fixed but do not know if it has been released or not.It used to work in workflow 7.0.1.Will post some more details on monday

thanks

To Mr Stytes,



Yes, i'm kinda get that, but you see , the Emailreciever is working fine.. ( as tested via the test tab ) + its working fine if no xml schema is given to it , in which case it takes default fields and continues.



The problem occurs when we're using a schema. and (maybe) its trying to fill in the init form using the XSD and form data using xpath. Thats probabaly where its giving an exception. But any case... if its a known bug. We're in the clear. Will post any issues .



Thanx



To workflow user,



I replaced all the dom4j jars with the latest 1.6.1 dom4j but , the same error is repeating itself



Please tell me proper workaround.



If no workaround is possible... please tell me how to change my workflow so that i can retrieve the form data properly ( or atleast get the workflow working)



Thanx
