C++ compiling error when FreeAndNil of private properties in an inherited structure with version 9.2.102.1293

Hello,

I spoke too soon my previous post. In another project, somewhat more complex, I’m getting a compiling error with the generated _Intf unit. I’m trying the gamma version 9.2.102.1293.

The problem occurs inside a ReadComplex method, in a structure inherited from another one that includes a third structure: I have an Address structure, then a Customer structure (which includes an Address structure) and a ExtendedCustomer inherited from Customer.

The error happens in the ReadComplex method of ExtendedCustomer, as the fAddress pointer is private to Customer, so the FreeAndNil fails with a compiler error E2247 “TCustomer::fAddress is not accesible”.

Here is the exact code:

	l_Direccion = this->int_Direccion;
	try
	{
		__Serializer->ReadStruct("Direccion", __classid(msaCI1ClientInterface::TDireccion),  &l_Direccion);
	}
	catch (Exception* E)
	{
		Uroclasses::RaiseError("Exception \"%s\" with message \"%s\" happens during reading field \"%s\".", ARRAYOFCONST((E->ClassName(), E->Message, "Direccion")));
	}
	if (this->int_Direccion != l_Direccion)
		FreeAndNil(this->fDireccion); // <-- this is the offending line.
	this->Direccion = l_Direccion;

I checked the Delphi code and as far as I can see (without trying to compile it) it produces something equivalent (the member is Private) but I don’t remember if the rules in Delphi are different regarding this.

Any recommendations to fix this? Hopefully you can get a fix for this for the RTM build.

Thanks

RTM was already created.
the fix will be in the next beta

Thank you Evgeny,

Any idea when the next beta will be available? I am not able to compile the codegen libraries myself.

For now I modified the generated file to use the Field directly, instead of fField. This at least compiles and should work… but I don’t know what route you took for the fix.

you can disable regeneration of _Intf and replace delete this->f with delete this->int_ like

delete this->fNewField;

with

delete this->int_NewField;

Ok, I will change the code to use the int_ version. Thanks.
