I dont' know the reason of this.
The exception remains if I update the jsp page and force its re-generation, but
if I restart the application server it disappears.
Any ideas?
NOTE: this exception appears more frequently in a page composed by three frames
self reloaded, and every frame uses the displaytag.
Thank you.
