Hi guys : I am , somewhat randomly, getting a "blank" page after submitting a JSP form.

The submission triggers a reload of the parent frame - call it 'p' - which refreshes both children frames - call the children 'c1', and 'c2'.

Normally, submission of the check boxes in the form works great, and the form submission and reload of frame works great,
and c1 and c2 are displayed perfectly.

BUT sometimes, i.e. if I select several { i.e. more than 8 } check boxes, the child frame RAPIDLY reloads as totally blank, with no other events. The top page looks dead, but is unrefreshed.

Any ideas about why submission of a jsp form would return a blank page and just die ?

I would say maybe it could be an exception, but I see no stack trace.....

Have you used an HTTP sniffing tool such as HttpFox to see what's going on with request and response?

A tool like HttpFox will show you exactly what's going on with your HTTP requests and responses and is the best way to start debugging issues like this -- especially if they're intermittent.

You can turn on Log4J debugging for FrontMan and that might give you even more clues.
 
It is sorta covered in the JavaRanch Style Guide.
