[osg-users] Error: 'Debug Assertion Failure!'

[Gordon Tomlinson]

I think you need to set your  (*ponto_itr) to NULL or remove it from the
vector after you have done the remove child, other wise the pointer still
has the address of the child you previously removed so you for loop above
(ponto_limp) will never do any thing

Hi, Rafa,

        I've tried doing something like what you've said before: every time
before I checked for selections with verifySelection(), I searched for a
NULL member and erased it, like it's done below. Can you tell me why it
still isn't working? Is there a logical flaw in my code? 

       Thanks,
           Renan M Z Mendes

        case(osgGA::GUIEventAdapter::KEYDOWN):
            {
                if(!ponto.empty())
                {
                    for(ponto_limp = ponto.begin(); ponto_limp !=
ponto.end(); ponto_limp++)
                    {
                        if(*ponto_limp == NULL)
                        {
                            ponto.erase(ponto_limp);
                        } 
                    }

                    for(ponto_itr = ponto.begin(); ponto_itr != ponto.end();
ponto_itr++)
                    {
                        if((*ponto_itr)->verifySelection())
                        { 
                            switch(ea.getKey())
                            {
                            case(ea.KEY_Delete):
                                {
                                    osg::Group* root =
(*ponto_itr)->getParent(0); 
 
root->removeChild(root->getChildIndex((*ponto_itr)), 1);
                                }
                            }
                        }
                    } 
                }
           }
