Hi Mehmet, I think you need change this line:
@Override
protected void setTDokar(TDokar dokart)
{
dokar = *docType*; -->
DocSearchPage.this.*docType
*=* *dokart;
}
anyway, why are you delegating the set/get model calls to
TDokarDocTypeDropDownChoice
? Won't be interest only use the parameter model to maintain the TDokar?
