Region with the same label declared on line [message #1776536]

I attached a image showing an error.
I think that it is a root cause to make functions that have same name.
Sometime, the code within error is deleted after code generation.
But it isn't an error in C++.
How to remove this error?

Hmm.. That is strange. I think I can reproduce the error. I defined a method "Operation1" in a capsule, and overloaded it. The generated code is as follows:

void Capsule_Top::Operation1( int n )
{
    /* UMLRTGEN-USERREGION-BEGIN platform:/resource/MethodOverloading/MethodOverloading.uml MethodOverloading::Top operation Operation1 */
    cout << "int: " << n << endl;
    /* UMLRTGEN-USERREGION-END */
}

void Capsule_Top::Operation1( string s )
{
    /* UMLRTGEN-USERREGION-BEGIN platform:/resource/MethodOverloading/MethodOverloading.uml MethodOverloading::Top operation Operation1 */
    cout << "string: " << s << endl;
    /* UMLRTGEN-USERREGION-END */
}

As your example, the comments are exactly the same.

At first I did not get any errors. But after doing a "clean" on the project I got the error markers.

This is certainly a bug, and it is caused by the Papyrus-RT/CDT integration builder which doesn't know about method overloading.

Nevertheless it does not affect the correct compilation and execution of the model as long as you compile using the instructions found at [1].

Although it doesn't affect compilation itself, it is annoying having those errors. For now the only workaround is to open the "Problems" view, and under "Errors" select the errors corresponding to those markers, then right-click -> Delete. You may have to do this after every "clean".

Alternatively, do not use method-overloading.

FYI, I've opened Bug 527414 for this.
