My memory is a bit fuzzy. I thought TextLine recycling wasn’t per-paragraph, or is there a TextBlock per paragraph?
The doc says that TextBlock.createTextLine/recreateTextLine returns null if the TextBlock is empty or if the width specified is less than the width of the next element, and to check the TextBlock.textLineCreationResult property if you get a null. Could it just be that the number of lines in the paragraph when to zero? -Alex On 11/6/14, 2:26 AM, "Harbs" <harbs.li...@gmail.com> wrote: >I ran into an issue where I have a runtime error in >TextFlowLine.getTextLine().
