Hi everyone,

I have a bit of a problem with the assignment of pointer-pointers. I have a main application and a dialog in seperate cpp/h files. In my main application I have a "dbo::ptr<Map> currentMap_;" (pointer to a map object) that needs to be manipulated in the dialog. at first I had passed the pointer to the dialog and worked with that. I could, of course, manipulate the object from within the dialog but the pointer to it remained unchanged. Then, luckily, I realized what a nooby mistake I had made. I don´t need to create a local pointer in the dialog that points to the same object as the dbo::ptr<Map> does; I need a * to change the object AND the dbo::ptr<Map> in the main application.
So I added a "dbo::ptr<Map> *ptrToCurrentMap_;" to the header and as long as I don´t assign it, the code compiles and runs. If I do assign it in the .cpp file (e.g. "(ptrToCurrentMap_) = currentMap_;"), the code compiles but crashes upon execution.
I´m quite the beginner when it comes to programming but I can usually handle the interface I´m currently working on. I had a heurika-moment when I realized I needed **´s (and that gives you an idea just how much of a beginner I am) but draw a blank as to why my **´s to dbo:: objects don´t work.
Using Eclipse under debian.

Any ideas/suggestions would be greatly appreciated.
