Hi Nick,
it's correct, what Derrell sad, we have done some optimizations for
performance reasons.
My first suspicion was that one listener is not removed when an object
is disposed, but with your information I can reproduce the issue, thanks:

It seems to me that the dispose method removes the table from the
container, but the layout queue tries to render it. Have a look at the
execute listener:
button1.addListener("execute", function(e) {
// works
win.remove(this.table);
this.table.dispose();
this.tableModel.dispose();
// throws an error: Remove Error: qx.ui.table.Table[undefined] is
not a child of this widget!
//win.remove(this.table);
this.createTable();
}, this);
The remove method only works, before the table is disposed. When I try
to remove the table after the dispose call, I get an error.
Could you please open a bug report with my tinyurl as example?
Thanks,
Chris

I think I figured it out. I traced back through the call stack
when it goes
to render the widgets and found that the table's parent had both
the old and
new tables as children. One of the tables was the correct one and
the other
was the one I disposed. I changed my reloadTable method to the
following and
it worked:
reloadTable : function() {
// clear the table model's row cache
this.__table.getTableModel().clearCache();
this.remove(this.__table);
// delete the existing table/model
this._disposeObjects("__tableModel", "__table");
// create table and model from scratch
this.__tableModel = new controlcenter.Model.List.TableModel();
this.__tableModel.addListener("metaDataLoaded",
this.__createTable, this);
},
I'm not sure of the differences between 1.0.1 and 1.1, but I know
that I
wasn't getting errors in 1.0.1. It seems I just need to remove a
widget from
a layout prior to calling disposeObjects on it.
Just a couple of weeks ago, there was a bunch of work done on
optimizing shutdown of applications. I believe there was work done
with disposing, possibly to the disposeObjects() method. It's possible
that it used to automatically remove the widget for you, and no longer
does so.
