Ext JS 4 Lockable Buffered TreeGrid

extjs4-lockable-tree's Issues

Stops working under ExtJS 4.1.1

Thank's a lot for this work, it really helped me implement a similar feature in my current project.

However, just FYI, the component stops working with ExtJS 4.1.1. Error in LockableBufferedTree.js, line 261. Basically the DOM element for the "normal grid" is no longer ready at the point updateSpacer() is firing. (Cannot read property 'dom' of undefined.)

I tried adding another condition to the if block for "&& this.normalGrid.getView().rendered". That skips this error but leads to more further down in the guts of ext-all-debug. Framework tries to call setHeight() on the DOM element of a CompositeElement (which I believe is the verticalScroller.stretcher). I tried to keep digging, but unfortunately I didn't get any further. At that point it's so deep into the layout or rendering cycle that I'm over my head and really not sure what to try and look for.

I have SVN access so I tried to compare tags for 4.1.0 and 4.1.1 to see if I could narrow down the change that is causing this, but it looks like the tags aren't publicly accessible. :-/

Regards,

Sch.mixin.Lockable setup failed, not sharing store between the two views

I am trying to make use of this component. However, when I create a new instance of the Ext.tree.Panel I am getting this exception. Can you please explain what this does?

if (this.lockedGrid.view.store !== this.normalGrid.view.store) {
  Ext.Error.raise('Sch.mixin.Lockable setup failed, not sharing store between the two views');
}
