ofxUIDropDownList getName() problem


I want to save the name of a selected item from a dropdwon list into a string variable.

I’m doing this in the ‘guiEvent’ method

void ParametersList::guiEvent(ofxUIEventArgs &e){
string name = e.widget->getName();

if(name == "Timestamps")
    ofxUIDropDownList *ddlist = (ofxUIDropDownList *) e.widget;
    vector<ofxUIWidget *> &selectedItem = ddlist->getSelected(); 
	for(int i = 0; i < selectedItem.size(); i++){
		cout << "TIMESTAMP SELECTED: " << selectedItem[i]->getName() << endl; 
		timestampSelected = selectedItem[i]->getName();


However, when i do “timestampSelected = selectedItem[i]->getName();” the program breaks with the following message:
“Unhandled exception at 0x5C76EB90 (msvcr110d.dll) in editorGUI_Test_debug.exe: 0xC0000005: Access violation writing location 0xCCCCCCCC.”

Btw, ‘timestampSeçected’ is a string variable from the class ‘ParamtersList’ itself.

I can see that the ‘guiEvent’ method is somehow blind to the rest of the class objects.
How can I do this in a proper way?

Thanks in advance!

Nevermind, the string variable was in the header file “ParameterList.h” instead of the CPP file.
Although it isn’t the best practice, changing this solved the problem.
Still have to figure out why …
