[BUG] Crash with Global Hand and Invisible String

[netninja]

So if you do these three things a SWF application will crash:

• Have an invisible string
• (SWF Object) Change the Global Hand to ON (doesn't matter if it is turned back off again later)
• Change to another frame

Example:

Press 'space' at anytime and the application will freeze.

Temporary Workaround:
Leave the string invisible and move it offscreen.

This may sound like an unlikely sequence of events but in a game I am working on right now I really need these things. I am using an invisible string to hold map data, the Global Hand turns on when the player is over a button and I need to change to another frame for the next screen.

Tested in Firefox 3.6.6 and IE 8 with Flash Version: 10.1.53.64

For Francois - what happens is this fails when the global hand is turned to on:

RangeError: Error #2006: The supplied index is out of bounds.
	at flash.display::DisplayObjectContainer/addChildAt()
	at Objects::CText/setHandCursor()

causing this to happen when the object is destroyed, because the child doesn't exist:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
	at flash.display::DisplayObjectContainer/getChildIndex()
	at Objects::CText/delSprite()
	at Sprites::CRSpr/kill()

Strange - I wonder if it's somehow related to my recent thread on invisible strings as well, and them not being counted in the object list in some way or another... no idea why moving it off-screen would help with that, though.

For the 'workaround' of moving it offscreen, I just meant that instead of making the string invisible I have been moving it offscreen where it can't be seen instead. If I made it invisible and moved it offscreen it would still crash.

I think you're right in saying it might be related to the post you made. At any rate, there seems to be some problems with invisible strings.

[DavidN]

Ah - yes, that was actually my solution to my strings issue as well - instead of making strings invisible, their Y position is just set to beyond the bottom of the screen.

Why not just set thier alterable string to "" ?

[DavidN]

That can work, but sometimes you don't want to do that, if you're relying on the content of a string even though it happens to be invisible at the time.

In that case why not add spaces so that it goes outside the string bounding box and thus can't be seen?

[RickyRombo]

What's wrong with moving it? :/

It can be seen with the zoom glitch.
