[4.0.2] one Store and two tree.Panel

[DDarko]

var tree_store = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: '/data',
reader: {
type: 'json'
}
},
root: {
text: 'root',
expanded: true
}
});


tree1 = Ext.create('Ext.tree.Panel', {
store: tree_store,
width:300,
height:100,
renderTo: Ext.getBody()
});

tree2 = Ext.create('Ext.tree.Panel', {
store: tree_store,
width:300,
height:100,
renderTo: Ext.getBody()
});


This is a bug or what ? :]
When navigating one of the trees begin to happen strange things.
Expanding and collapsing part of the first panel action is executed on the second. Items disappear from the second tree and duplicate the first.

Sharing Store, it seems logical. It is possible?

Sounds like it to me, sending one of our support guys this way

Confirmed as a bug and opened a ticket

I've also encountered this problem and there are additional strange behaviors like auto-scrolling doesn't work in the second tree and both trees will suddenly stop expanding and collapsing nodes. In my case, the trees are on a menu invoked from a button. Has the bug been targeted for a release? Is there a workaround?

[germanicus]

I just checked the ticket, and it has not been scheduled for a release yet. If a workaround becomes available, I will post it to this thread.

Why was this thread marked as fixed? I experience the same problem (using ExtJS 4.0.7)! Collapsing & Expanding causes the items in "Exclusion masks" jump to the upper tree. Also when I change checkboxes in the upper tree, the changes are reflected in items of the lower tree instead of the upper one.

The fix didn't make it into 4.0.7. It will be in 4.1.0.

Ok, thank you for the update!

Is it fixed in ExtJS 4.1 ? I am still seeing this behavior in ExtJS 4.1.1a release.
