Automatically open grid filter when opening form

In some forms it may be convenient that the grid filter (new in Ax 4.0) is activated automatically. If you want to get that behaviour, just add one line in the form's run method, just after the super() call:

this.task(2855);

So, your run() method should look like:

public void run()

{

..... // some programming lines....
super();
this.task(2855);
}
