one page there is a fileUpload function using t:inputFileUpload.
Sorry, I have forgotten my crystal ball at home today and do not see what is on your page pretty clearly. If you try to have a t:inputFileUpload inside the form sending by Ajax, just even do not try. Browser (any kind) restricts this feature (just a obvious security reason)
Sorry, I didn't stated clearly. On the fileupload page, there was no Ajax. But we had some other pages in same application using Ajax. In which all the ajax functions didn't work without myfaces-all.jar.
Sounds like some configuration issue. Do you have any error messages/stacktrace? May be you missing some other classes that was included into myfaces-all.jar?
I removed tomahawk-1.1.5.jar, included myfaces-all.jar, and changed
extensionsFilter class config from
Then both ajax pages and fileupload page worked. However, I don't know why org.apache.myfaces.webapp.filter.ExtensionsFilter in tomahawk-1.1.5.jar broke the ajax functions.
