When the cardinality of OwnedArray Object is equal to 1, oa.remove(0) will crash. :?:
Could you help me?
thanx
OwnedArray problem size = 1

…by cardinality, you mean the size of the array?
It’ll only crash if there’s a problem deleting that object - most likely you’ve already deleted it by some other means and you’ve got a dangling pointer.

Yes Jules, the size.
Exactly, the remove() crashes in the last line
...
irList.insert(0,&dlgResult);
removeFilesWithoutTheseProperties(getFilter()->getNumOutputChannels(),getFilter()->getSampleRate());
...
In removeFilesWithoutTheseProperties I do
irList.remove(i);
It is the same I do when irList has more than one objects.
It crashes only if irList.size() = 1.

Looks like a basic c++ blooper to me. You’re adding a reference to something, then deleting the object, which is maybe on the stack?

When irList has more objects I use findChildFiles to fill it.
In this case I have only one result in dglResult, it is a member of the Editor class.
So you think it is better,in this case, set the 0 element to NULL instead of removing it?

Instead of
irList.insert(0,&dlgResult);
I do
irList.add (new File (dlgResult));
It seems to work fine now.
