sorry, in my Email is the folow method incorrect:
@Override
protected void setTDokar(TDokar dokart)
{
dokar = docType;
}
in source cod is in code looks like this:
@Override
protected void setTDokar(TDokar dokart)
{
docType = dokart;
}
docType is still null.

Betreff: Re: problem with Dropdown List
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?
