Subject: [jira] [Commented] (FLEX-34988) Number of characters with images is
 wrong

Harbs commented on FLEX-34988:
------------------------------

Here's the reason for the discrepancy:
ParagraphElement.getText() has an optimization where it gets the TextBlock.content.rawText if the TextBlock has been created. A TextBlock is only created if the text has been composed. The rawText includes a unicode point for the inline graphic. (I think the unicode point is \uFDEF.) If the TextBlock does not exist, it recursively calls getText() for all the sub-elements. InlineGraphicElement does not define a getText() method, and the getText defaults to the method in FlowElement which returns an empty string.

I'm not really sure what the "correct" behavior is for getText() on InlineGraphicElements... I guess we can add getText() to InlineGraphicElement which returns \uFDEF to be consistent with rawText in FTE. I'm not sure what else to do.

> Hi, I have a problem when I insert images in the text. When I get the text of the TLF the number of characters is wrong. It only counts the images that are displayed. 
> I build a test code to see the problem.
> -----------------------------------------------------------------------------------------------
> I added 3 images, but getText() function only returns the last one.
> NOTE_1: 	If you uncomment [oController.verticalScrollPosition	= 0;] line after adding the 3rd image, it returns the first two images.
> 		So, it seems getText() function only returns the images that have appeared on screen.
> NOTE_2:	On the other hand, as you can see in the example, the [textLength] attribute returns one more character than [getText().length].
