I think the root of the problem is that BaseCompose.createTextLine() is returning null. The only reason why that would happen is if the line couldn't fit in the space provided. I am not sure why ComposeState.composeNextLine() is trying to do _curLine.getTextLine(true) when the textLine is null. I would think you would hit the same result or something worse like an RTE.
What parameters are you passing into FTE when trying to create the line? On Thu, Nov 6, 2014 at 2:09 PM, Harbs <harbs.li...@gmail.com> wrote: > Yes.
