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

HI Renan
 
Sorry my bad, I was thinking of Vega and Vega Prime how children work there
 
Looking at getChildIndex it returns the size of the children array if Child
node is not found.
 
 
This seems like a subtle bug because it returns a Zero for no children, but
zero is a valid index, perhaps this function should return  -1 if no
children or something as zero is clearly wrong here
 
 
Also as pointed out you need to make sure can clean up your array after you
remove a child as the pointers you have may no longer be valid etc

Hi, Gordon.

      I've looked up the doxygen documentation, and the second argument of
removeChild is numChildrenToRemove, which I thought stood for 'number of
children to remove'. If so, wouldn't I want 1 child to be removed? Isn't my
index correct? 

                 Thanks,

                     Renan M Z Mendes
