Problems with migration to FB 4.5

Question

I had been working with FB4 premium and just purchased FB4.5 premium with Flash cs5.5.
I am having a BIG problem importing my old projects from FB4.  AKA: "VerifyError: Error #1053: Illegal override of createGeometry in flashx.textLayout.elements.FlowGroupElement".
Please a answer to this would be great, I have read already 3 different post describing the same problem without appropiate answer. The best i got was a confirmation that the problem relies on the TLF and a referral to the TLF forums which have NO answer to this.
the debugger doesn't even take me to a line to help me figure out how to solve this.
I have already read that the problem lies in the new version of TLF (2.0) None the less I find NOWHERE a way to solve this out.
I've tried downgrading the SDK to 4.1 and or changing the reference of the textLayout.swc to the older and/or newer version and none of this helps.
Dismissing the error, will runs the project but not even the Debugger will show up and the text will be buggi as the visulas overall.
Thank you

Hi,
I ran into similar problems as gv4.me opening a Flash CS5.0 document with Flash CS5.5. It seems to me that the TLF-Text Enginge inside the IDE 5.5 work completly different.
First thing what happened when I opened the old CS5.0 and try to comile was
ReferenceError: Error #1065: Variable TCMText is not defined.
ReferenceError: Error #1065: Variable TLFTextField is not defined.
Thx to kglad's tip
if you do need tlf text, select the merge into code for runtime shared libraries.
descriped at http://forums.adobe.com/thread/863163#863163
this Reference Error disappeared after setting "merge into code" for the textLayout.swc in the advaned actionscript settings panel.
Now I have another Problem regarding TCMText and TLF-Text.
To keep it simple let's assume we have serveral TLF-Text instances on the stage created with the TextTool (Hotkey T) inside the Flash CS5.0 IDE.
We want to animate only these TLF instances regardless what else might be available on the stage.
As the fla was created by our designer, we don't know exactly how many instances have been placed on the stage. So we write us some code to check
wether the currentDisplayObject on stage is a TLFTextField.
public function get aBuchstaben():Array
            var aTLFLetters:Array = new Array();
            var currentDisplayObj:*;
            for (var i:uint = 0; i<this.numChildren; i++)
                currentDisplayObj = getChildAt(i);
                if(currentDisplayObj is TLFTextField)
                    aTLFLetters.push(currentDisplayObj);
            return aTLFLetters;
This code works perfectly with CS5.0 and when we trace the generated array it gives us all the TLFTextFields we want to animate.
Now, let's open the same fla in CS5.5 and try our code again.
Nothing will get traced! Our generated array is empty. It could not find any TLFTextField on stage...very strage don't you think?
Well, let's debugg and see what's going on. Our TLF-instances on stage are no longer instances from the TLFTextField class. Instead we can see that all instances are now instances from a strage class called fl.text.TCMText.
First I thought that this might not be a big problem and I could easely change the code to check for TCMText instead for TLFTextField, but I was wrong. The TCMText class can't be imported nor is it possible find some more informations about this TCMText class.
The official adobe help
http://help.adobe.com/de_DE/FlashPlatform/reference/actionscript/3/fl/text/TLFTextField.ht ml
lists only the TLFTextField unter the fl.text package. It's not even listed on the beta help:
http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/fl/text/package-de tail.html
Seems to be that there are more migration problems regarding TLF-Text between CS5.0 and CS5.5 which are nowhere documented. 
After hours of searching I found this information:
TCM text for static TLF Flash Pro CS5.5 uses the Text Container Manager to handle TLF text that is not intended to change at runtime. The TCM avoids the need to include the full TLF ActionScript library in the published SWF file, significantly reducing file size.

Sounds good, but where can we find some more information abouth this Text Cotainer Manager and how to handle TLF text that's not changeable?
Wait what? TLF which is not to change at runtime?
Mhh, then let's try out our fla again and edit each TFL-Text and make it editable:
Debugg again and whoooa, there are now some real TLFTextFields inside the generated array. Isn't this strange^2 ??
Now everything seems to work, except that the TLFTextFields instances are now editable...compile the fla again and you can write stuff inside each
TLF-instance. Well it behaves as expected but it's not what we needed.
How can we change the instance again so that it keep being an instance of TLFTextField and is not editable at the same time?
I tried to set selectable to false
TLFTextField(currentDisplayObj).selectable = false;
and a lot other stuff but's nothing is working.
I ended up beeing nearly as frustrated as JVLL.
Hope anybody helps what I found out so far.
Please adobe developers spread some more information about this new TLF-Text and its new Text Container Manager classes...
