[gme-users] Regarding Moving Objects through BON

[Jae young Bang]

Hello Csaba,

The GME I'm using is 7.6.29.

The situation here is that the project I'm using for testing uses the  
built-in UML paradigm. I haven't moved the UML decorator. So it might  
not be the problem.

I'm guessing if it might be because I created a new Territory to  
retrieve an object handle by the relative ID. Is it possible?

Below is more of the codes if it could have a clue. The error comes up  
at the last statement with setLocation().


	std::set<BON::Object> objs = findByKind(type);
	std::set<BON::Object>::iterator it;

	long rID;

	for(it = objs.begin(); it != objs.end(); it ++) {
		(*it)->getObjectI()->get_RelID(&rID);

		// if this object is the object we want
		if(rID == relID) {
				
			// overwrite the name
			(*it)->getObjectI()->put_Name(CComBSTR(name.c_str()));
				
			// if it has position registry, overwrite it
			Atom atom (*it);
			if(atom)
			{
				Point p;
				p.first = x;
				p.second = y;

				atom->getRegistry()->setLocation(p, "UML");

			}
		}
	}



Thank you very much for your help!

Regards,
