Ok. Thanks for all the comments, they have been most helpful.
On the point of the jsessionid, it works with or without the id there. I
have it in as a check for something completely different and have since
removed it anyway. Thanks for the comments on it though.
I have found that the problem is not actually in the form bean (which is
extending the ActionForm class), but more to do with *when* I attempt to
access the bean.
I have this situation.
* The form is filled and the user submits.
* Struts is forwarded to my ActionClass for this form.
---- Problem starts here ----
* I need the information from that bean, to activate some business logic, so
I take the form from the execute() parameter list and pass this to the
business layer (Where it has no content!!).
* After the business layer has finished, I put the form in the request as
follows
SignalSelectForm currentForm = (SignalSelectForm)form;
request.setAttribute(StrutsCXConstants.CURRENTFORM, currentForm);
and then forward it to a servlet.
---- Problem ends here ----
* The servlet then gets the form using the *exact* same CURRENTFORM, and
then processes the form in *exactly* the same way as the business layer does
(it is the same code) but it gets the data out.
Any ideas??
Cheers, and thanks again for the comments,
Simon

Jsessionid is being generated by the <html:form/> tag. The problem is in
your form bean implementation of the indexed property named 'signals'. In
your form bean you didn't implement your 'signals' property as indexed
property correctly.

I know that, but simply I've never had to pass that info using a form. :-]
Why do you put the session id in the form?
