TreeStore - getModifiedRecords problem

[ionut.rachita]

Hello,
I'm doing some modifications over a TreeStore, removing and adding items. After doing this I'm retrieving the list of modified records with getModifiedRecords, and I get an empty list.

Throwing a quick look over the TreeStore class I saw that "modified" variable is used only in removeAll. From my impression after modifing a treeStore is not possible to retrieve the modifications.

So my question is, how can i retrieve the modified records, or more precisely if a treestore was modified? Is there a way to do this, or this is a bug?

Regards,
Ionut

I've posted in the bugs subforum about this issue, along with a code sample.

I've not used the TreeStore myself but could you not make your own class extending TreeElement (or whatever it is) and override modify/setValue method and set the modified field yourself?
@Override
modify(modification a){super(a); this.modified=true;}

It does however sound like a bug to me, or maybe just a design decision by the makers.
