Welcome to the JavaRanch, Taieb!

You will get much more useful error messages if you set the "id=" attributes on your JSF View Definition tags. Do this especially for input controls and containers such as forms, dataTables and panelGrids.

We also have a special "Code" tag that can make your java code and XML samples easier to read. There's a button on the CodeRanch message editor for it.

Based on a superficial look at your stack trace, I'm guessing that you are attempting to modify the JSF response headers and/or the response output stream. You should not do that. In particular, if you are attempting to output PDF files, Microsoft Office documents or other non-HTML output, you should use a servlet instead of a JSF handler.

Since the IDs in the example were all auto-generated, it's obvious that you didn't include them in the first place even without reading the actual VDL. You can't delete or change what doesn't exist!

JSF auto-generates component IDs for its own internal use if you don't provide explicit IDs of your own. However, these generated IDs are nearly impossible to cross-match back to the controls that they represent.

the dynamic menu and the accordion menu have caused the problem. I added an id for each component and also for form and now all is well. thank you very much for your help.
 
Don't get me started about those stupid light bulbs.
