[Users] Redlining Popup trouble

[jonathan Maura]

Hi all, 
I want to use the ux Redlining in my application. 
I use this code to add redlining buttons:

var Tools = new  Ext.ButtonGroup({
		title: 'Add Content',
		columns: 8
	  });
       
        var controler = new GeoExt.ux.FeatureEditingControler({
            id:'controler',
            'cosmetic': true,
            map: this.map,
            styler: 'combobox',
            popupOptions: {anchored: false, unpinnable: false,
draggable: true}
        });
       
  
        Tools.add(controler.actions);
        toolbarItems.push(Tools);

But i have encountered trouble with the editing popup. 

With point and label, the editing popup automatically close (without any
user action, popup is active & the bbar element isn't active) 

I look at the FeatureEditingController.js and add a block comment into:

onModificationEnd:
...
 if (feature.popup) {
            //feature.popup.close();
            //feature.popup = null;
        }
...
that allow me a "pseudo-persistence" (only for the "draw a point" tool).
I think that an event from my app "hit" the popup component and force it
to close. 

Does anyone have  a clue? 
Thanks for your time!
Jo
