Invalid cast followed by crash in DepersistFromTransitionFormat

[jasper]

The implementation of DepersistFromTransitionFormat?, in the COBIA.h C++ header file, contains an invalid cast, which leads to a wrong VTable on the returned transition format reader (the output argument of this function) which leads to a crash in instantation of a COBIA PMC that uses saved information from a COM PMC.

Old implementation

	 inline COBIA::CapeBoolean DepersistFromTransitionFormat(/*in*/ICapePersistReader *reader,/*out*/CapePersistReader &transitionFormat) {
		COBIA::ICapeInterface *output=nullptr;
		COBIA::CapeBoolean bres=COBIA_INTERNAL::COBIAFUNCTIONS::instance().cobiaDepersistFromTransitionFormat((COBIA::ICapeInterface*)reader,output,1,2);
		if ((bres)&&(output)) {
			ICapePersistReader *r=(ICapePersistReader *)output; 
			transitionFormat=r;
			r->vTbl->base.release(r->me);
		}
		return bres;
	 }

This invalidly casts the returned output pointer to an ICapePersistReader *. The actual implementation of cobiaDepersistFromTransitionFormat performs a cast from the implementing object to ICapeInterface*, not to ICapePersistReader*.

									COBIAPersistReader* reader=new COBIAPersistReader(node,COBIATEXT(""));
transitionFormat=(COBIA::ICapeInterface*)reader;

Correct implementation

	 inline COBIA::CapeBoolean DepersistFromTransitionFormat(/*in*/ICapePersistReader *reader,/*out*/CapePersistReader &transitionFormat) {
		COBIA::CapeInterface output;
		COBIA::CapeBoolean bres=COBIA_INTERNAL::COBIAFUNCTIONS::instance().cobiaDepersistFromTransitionFormat((COBIA::ICapeInterface*)reader,&output,1,2);
		if ((bres)&&(output)) {
			transitionFormat=output;
		}
		return bres;
