It's a little trickier than that, because StageText itself is wrapped in a ScrollableStageText (or StyleableStageText depending on the skin) So SkinnableTextBase.textDisplay is the ScrollableStageText which is a (pooled) wrapper around StageText. And the pool has two static dictionaries ( SST => ST and ST => SST). So seeting the listeners on the SST locks the TI, because the SST are also referenced in the pool dictionary. Makes sense to you?

I assume that 'textDisplay' isn't a StageText in a pool. If that's true, the SkinnableTextBase.as is correct. I would expect that 'textDisplay' is a StageTextInputSkin and internally it should be adding weak reference listeners to the actual StageText's in the pool. Or are those bad assumptions? -Alex >
