Well, in Flex the TextArea dosn’t have a redraw() - Method, right? I solved it just by putting a
TextArea.htmlText += ” \n”;
after the TextArea is created. May help sombody. It’s dirty, but It helped me.
Cheers

Sorry, wrong link. Click on “TextArea class” under “Related topics” to see a list of all the TextArea’s methods.

Has anyone tried this? It’s faster than TextArea.invalidate(). Although I’m not trying to load images into my TextArea, it solved a similar problem I was having:

TextArea.redraw();

Forces validation of the object so it is drawn in the current frame.

I have a similar problem…

flash 8;
I load images and text (html) from xml in a the textarea.
When you scroll that textarea, the image becomes weird; Especially when you put another text ( image) from in the textarea.

I tried myTextArea.invalidate() but no luck

any ideas to fix this one?

dammit.. I just got caught in this hell. I’ve been here before a year or two ago, but haven’t had to deal with this since and I’ve forgotten how to work around it, can’t find the project where I came up with a workaround, etc. I guess this is the stuff that separates the hard core Flash developers from the Java developers who dabble in Flash (the ones I know go crazy over stuff like this and give up).

It’s not the TextArea’s full fault, but Flash TextField’s. Have you every played around putting images in TextFields? They are, franly, pieces of crystal; they look good initially, but once you modify them, the textfield gets all wonky and whacked out. I’ve had serious issues over the past week, confirmed by reading other reports of serious TextField digging on the net, that Flash textfields have serious rendering issues, caused half in part by invalid HTML, and …well, not sure the other half.

If you cannot re-write the HTML yourself (if you look at the HTML Flash textfields generate, it’s abhorrent), then yeah, invalidate till the cows come home. I’ve always been lucky with 3 onEnterFrames; your milage may vary.

Hi Christophe,

Thanks for the suggestion. I tried it, but alas, the scrollbar/thumb is still initializing incorrectly. I even went through an diffed all my base classes in mx.core.* and mx.controls.TextArea, etc. to make sure that *I* didn’t mess something up while in one of these files and they all diffed perfectly with the original copies in FirstRun.

I’m going to try and see if SWFs behave differently but I’m not very optimistic that they will.

Make sure you put every tag in a

tag and that you close the

tag.

Seems like the V2 component contain several bugs and haven't been tested very well before releasing them.

Hope that helps.
