org.apache.wicket.WicketRuntimeException

Hi,
I get the following error in the webclient when I have two users open a Form using showFormInDialog() and try to do the same thing:
org.apache.wicket.WicketRuntimeException: After 1 minute the Pagemap Template_Selection is still locked by: Thread[TP-Processor3,5,main], giving up trying to get the page for path: 0:2

To explain a little bit further, what the form does is it tries to mailmerge into a word template letter after the user selects a particular type of template (this was done using plugins by it2be). So when a user has a form open in showFormInDialog, it doesnt close but shows loading… while the mailmerge process is doing its thing. Now at the same time, if another user tries to do the same, we get the aforementioned error.

If you have any idea how to resolve this issue, please let me know. Thanks.

Regards,
Sunil.
