comboxitem changed called twice

[aranape]

Using the latest lgpl version.

Is normal this behaviour?

When inside a changed event of a comboxitem i hide another field , then changed is called again.

changed: function(form, item, value) {

     var record = item.getSelectedRecord();
      myForm.getItem("aField").hide();
}

without the hide call , CHANGED is called one time and record is correctly defined.
With the call to hide , changed is called twice and the second time the combobox field goes empty and record is undefined.

Why?

A little investigtion , looks like when a field is hidden al the form need to be repainted , but why changed its called again?
