It took a while to figure out my sorting problem (the good news is I am
diving into source code and finding my problems).
Ideally, the sortByColumn functionality in Remote.js is enough to fire the
_loadRowData() function.
I think it is dispatching a wrong event.
I had to override that method to fire right event in MyRemoteTable.class as
// overridden
sortByColumn : function(columnIndex, ascending)
{
if (this._sortColumnIndex != columnIndex || this._sortAscending !=
ascending)
{
this._sortColumnIndex = columnIndex;
this._sortAscending = ascending;
this.clearCache();
// Inform the listeners
this.createDispatchEvent(qx.ui.table.ITableModel.EVENT_TYPE_META_DATA_CHANGED);
}
}
It should fire EVENT_TYPE_META_DATA_CHANGED instead of
EVENT_TYPE_DATA_CHANGED. Can somebody fix the code please?
Thanks.
