   hi guys, i have 99.5 rc1 and the following problem

   CCLabelTTF *plabel = [CCLabelTTF labelWithString:@"250" fontName:@"Marker Felt" fontSize:64];
   
   plabel.position = b.position;
   [self addChild:plabel];
   [plabel runAction: [CCFadeOut actionWithDuration:2]];
   [self removeChild:plabel cleanup:NO];

   with this code the label 250 doent show.. if i take out removechild the FadeOut action run as expected.. but of course i need to remove that label, when the action is over.. i need to show the fadeout effect!

   cleanup:NO (or false or FALSE) isnt soppose to let the child terminate all actions?

   Running the action doesn't block until it is done, it simply starts the action, then continues to execute code.

   Basically, you are starting the action, then immediately removing the sprite as a child, so it won't show anymore.

   I think you can use a sequence like such:

   id fadeOutAction = [CCFadeTo actionWithDuration:2 opacity:0];
   id removeChildAction = [CCCallFunc actionWithTarget:self selector:@selector(removePlabel)];
   
   // removeChildAction is performed after fadeOutAction is completed
   id sequence = [CCSequence actions:fadeOutAction, removeChildAction, nil];
   [self runAction:sequence];
   
   - (void) removePlabel
   {
        [self removeChild:plabel cleanup:NO];
   }

   Note that I used CCFadeTo instead of CCFadeOut due to the open issue 828.

   cleaner code:
   

   id act1 = [CCFadeOut actionWithDuration:2];
   id act2 = [CCCallFuncND actionWithTarget:plabel selector:@selector(removeFromParentAndCleanup:) data:(void*)YES];
   id act3 = [CCSequence actions:act1, act2, nil];
   
   [plabel runAction:act3];
