I wrote a Custom locator using MPxLocatorNode in C++. I have very special requirement for this locator. This is mainly targeted for using as rig controls as well as Character picker ui element. So, i provided an option to use it as button(like a normal push button which should execute some command and deselect itself). Tried implementing this pushButton kindof feature inside the draw call of locator. I simply check the status(MDisplayStatus) and de-select the object using MGlobal::unselect(path.node()) (path is the MDagPath from the locator draw function). Well, this crashes maya. I couldn't really debug this problem. From what I understood, it looks more like a memory access violation. Any workaround for this problem?
