Ad Miel commented on FLEX-20864:
--------------------------------
I use Flex 4.6.0.23201 and I get still this issue with
setFormatOfRange(textLayoutFormat), but there is a workaround: when I use
IEditManager( editor.textFlow.interactionManager ).applyLeafFormat(tf) it is OK
Also remember to set
import mx.core.mx_internal;
this.mx_internal::clearUndoOnFocusOut = false;
because these operations causes to loose focus and then undo stack is broken
(by design)
> Break stack undo in RichEditableText when I make one or more operations
> ApplyFormatOperation sequentially

> I found a bug with undo when I make one or more operations
> ApplyFormatOperation sequentially. this breaks the stack of undo, not undoing
> the other operations when press control-z, or call undo();

> amet" id="rt" />
> function applyFormat(){
> var textLayoutFormat:TextLayoutFormat = new TextLayoutFormat();
> textLayoutFormat.fontSize = 20;
> textLayoutFormat.color = 0xFF0000;
> rt.setFormatOfRange(textLayoutFormat);

> OR
> function applyFormat(){
> var cf:TextLayoutFormat = new TextLayoutFormat();
> cf.fontSize = 20;
> IEditManager( rt.textFlow.interactionManager ).applyLeafFormat(cf);
> }
