I make a new deploy and the app works fine for 5 minutes, then I get this error again....
Any idea?
Thanks a lot for your time on this thread.

You may have deployed multiple applications to WAS.
As you can see this issue is typically due to having two model objects
(or view or component etc) in two wd projects respectively with the samemodel name and the same model package it will confuse the classloading
system. Please check to make sure that all your view/component/model
names are unique across all deployed Web Dynpro projects.

Hi Subramanian:
I know it and if I perform the change it works, but It's hard to believe that having each app it's own namespace the WAS have this kind of problems. I would like to have it fix it from the server side, so I'm searching If there's the way.... with this problem I can't have a project and re-use it.
Thanks a lot for your time and answers.

Hi there,
Did you recently upgrade your system? Which version are you in? Are all the hotfixes for the version applied? Try it, because sometimes upgrades causes these issues,

Hi L. Menon:
Thanks for your answer.
There was no set up of any hotfix or SP.
Something strange is that if I test the app with the "Web Dynpro Administrator console" the apps works fine, there's no class loading issue and there's no error, but if I test it at SAP Portal the error appears.
Thanks.
