Summary: How to refresh a form using a groovy rule?

Content (required):

Dear all,

I've written a Groovy rule to add some complex control before saving data.

This rule is atached to a form and it run before Save.

If it gets through the controls then I build a FIX ENDFIX statement on the fly and then I send data to essbase in the same Groovy rule using cube.executeCalcScript method.

Now I'm looking for a Groovy method to realise a form refresh as if I'm clicking in the top right corner of the form in order to re-initialize the grid.
