Thanks for your reply. actually, my bind function
looks like:
this.invalidateList();
this.invalidateProperties();
this.invalidateProperties();
this._boundData = new XMLList(data_);
this.dataProvider = this._boundData..Row;
It will redraw the table, but it will not generate more columns if
the next dataset has more columns.
I might be on completly the wrong track, but I tried to trace where
it ignores the new data, and it appears to occur in DataGrid's
generateCols() function.
inside, there is this obj introspection -
var info:Object = ObjectUtil.getClassInfo(iterator.current,
["uid", "mx_internal_uid"]);
but in this it will always check internal cache for xml objs,
therefore ignoring the new xml obj.
I think I am going about this wrong, or I am missing something -
Thanks!
