Attach external documents using UWL

Hi,

We were planning to use SBWP transaction in WebGui for the web access of the workitems. But we have some critical workflows which require user to attach some external documents (in different formats like doc, xls, pdf). When we open the workitem in webgui and try to attach a document, we getting an intermediate screen with heading "Enter Some file attributes" and a little later we get a message in status bar saying "Load applet failed" and the flow struck there. If we hit back, we get "Session expired message".

Does anybody have a solution to fix this?

Also if we implement UWL will this problem go away i.e if the work item is opened in UWL, can we attach any document to any work item without any problems? If so, are there any specific requirements for this ? Please let me know. We are using EP 6.0. Appreciate your help.

Thanks

Hari
