Beta 10: ForEach crash

[AndyH]

Hi

I get a crash in the foreach code in xcode on the last line of this snippet:


-(void)actionint)num withActExtensionCActExtension*)act
{
switch (num)
{
case ACT_STARTFOREACHLOOPFOROBJECT:
{
NSString* loopName = [act getParamExpString:rh withNum:0];
int oi = [act getParamObject:rh withNum:1]->hoOi;


It worked when I had one ForEach running, it started crashing when I started running two ForEach loops (independently of each other on different objects). Not doing anything complicated, just running two ForEach loops, each loop on a different object and there are more than 10 instances of each object.

I see a possible cause for this:

MMF2 still triggers the action in the extension even if there are no currently selected objects. It gives a null-pointer in that case which extensions should just check for. The iOS ForEach object port was missing this check and crashed. Fixed for next beta.

Perhaps you can work around this bug by comparing the number of objects is > 0 before starting the loop (temporary fix until we post the next beta)

Thanks, will try that out and let you know.

Unfortunately it still crashes. I will send you my app to examine, maybe I'm doing something specific to trigger it?

Was my mistake, I still had my fastloop version of the events in place (in a disabled event group) and I had added the work around to that and not to the ForEach event - doh!

Can confirm this fixes the problem. Andos has fixed the ForEach for the next beta too and we've confirmed this works for my situation
