[jira] [Commented] (FLEX-20864) Break stack undo in RichEditableText when I make one or more operations ApplyFormatOperation sequentially

    [ https://issues.apache.org/jira/browse/FLEX-20864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13485601#comment-13485601 ] 

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)

> 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();
> <s:RichEditableText width="500" height="500" content="Lorem ipsum dolor sit amet" id="rt" />
> function applyFormat(){
>      var textLayoutFormat:TextLayoutFormat = new TextLayoutFormat();
>      textLayoutFormat.fontSize = 20;
>      textLayoutFormat.color = 0xFF0000;
>      rt.setFormatOfRange(textLayoutFormat);
> }
> OR

>      var cf:TextLayoutFormat = new TextLayoutFormat();
>      cf.fontSize = 20;
>      IEditManager( rt.textFlow.interactionManager ).applyLeafFormat(cf);
