GWT 2.6 js null symbol, compiled mode

Question

I get this error in FF/Chrome console when using the compiled version of my application saying:

"TypeError: a is null"  

So I went to the symbol map and searched for symbol a but no occurrence ...
I don't get this error on hosted mode, and it only started to appear since migrating to GWT 2.6
Any idea? Thanks

Answer 1

Ok I found the solution, if anybody's facing the same problem when on compiled mode, look for the symbolMap of the correct permutation in your WEB-INF/deploy folder. This helped me to find which method is causing the error and fix it.

Answer 2

Maybe try to compile in Pretty mode to have a more explicit symbol name.

Not sure it has anything to do with GWT 2.6. Same code in GWT 2.5.1 does not have the same error ?
