FilterHeader plug in removed by grid.reconfigure(columns)

Ext.NET forum thread: filter header disappeared after reconfig with new cols

When a grid with filter headers is reset via the grid panel's reconfigure(columns) call (when you specify the new columns to reconfigure the grid with), the filter header fields are not added to the column title.

After the reconfigure (or before) calling grid methods to add columns works correctly and the field is introduced correctly.

Just as a side note, for Ext.NET MVC, just getting a grid from a direct event/method wouldn't make it so code behind knows about the grid having the FilterHeader plugin, so even AddColumn() and InsertColumn() will not craft the column object to include the right fields. In such situations where the grid is retrived via X.GetCmp(), the FilterHeader plug in should be reattached to the grid object for the side effects to take place, for example:

var grid = X.GetCmp<GridPanel>("GridPanel1");
grid.Plugins.Add(new FilterHeader());

This is a limitation from MVC, not a bug.
