The error says:

The concrete syntax is not loaded

This means that you use a grammar where each concrete language is stored in a different file. In this case you need call:

concr.load("concr file name")

before using that language. Here concr refers to the object corresponding to that language.

Thanks for the quick response. Ok,But I am loading concrete syntax on start. The log says

Trying to open gfoffline/App.pgf
gfoffline/App.pgf loaded (608 ms)
Trying to load gfoffline/AppJpn.pgf_c
Trying to load gfoffline/AppEng.pgf_c
gfoffline/AppJpn.pgf_c loaded (940 ms)
gfoffline/AppEng.pgf_c loaded (2227 ms)

And English to Japanese works 1st time, then I switch to Japanese to English which also works just fine. The issue happens when I switch back again to English to Japanese. I have to load the concrete syntax again?.

Are you sure that you don't unload one of the languages somewhere, or that you accidentally start using another language? I don't know any other reason why that might happen.

Yes you are right. While setting setTargetLanguage unload of previous concrete syntax is happening,I didn't noticed it. I think I have to handle this myself, anyway thanks for pointing me in right direction.
