Subject TextFlowLine recycling
Date Thu, 06 Nov 2014 10:26:04 GMT
I ran into an issue where I have a runtime error in TextFlowLine.getTextLine(). I’m having
trouble stepping through things, but as best as I can figure, the issue is caused by the umber
of lines in a paragraph becoming reduced.

The RTE happens inside TextFlowline.recreateTextLine() after requesting the line from the
TextBlock. The function (I’m not sure if it’s createTextLine or recreateTextLine) returns
null. The TextBlock.lastLine is the line before the current one.

The caller of this mess is ComposeState.composeNextLine.

If anyone is still following me, my problem is I’m not sure the best way to fix this. I’m
not sure why this is breaking now. I’m not sure what I changed that’s causing this error.
Should I fix TextFlowLine.getTextLine() to return null if there’s no more lines in the paragraph?
Will there be any other repercussions from doing that? Should I fix ComposeState/BaseCompose
 so it does not try to compose the next line once the paragraph is out of lines?

Is anyone familiar enough with the composer to even give me suggestions? :-(
