From an email from Sallen:

in sending events the LFC has special logic to tell if the
>> user clicks on an input text or selectable text field (since we don't
>> get the movie clip that was clicked on from Flash, but we can find out
>> what movie clip is the selection. This logic is in LzModeManger. To
>> find the view associated with the movie clip, we rely on a property
>> that the text views set on their corresponding movie clip. That used
>> to be called 'view' but was changed to '__lzview' at some point for
>> inputtext and seems to have gotten lost for test. This change fixes
>> that.
