Timing problems disposing components in google closure

I was receiving the following error while trying to remove a component in Closure (seamlessField):

 this.getEditableDomHelper() is null  

 [Detener en este error] var win = this.getEditableDomHelper().getWindow();   

The component was to be disposed after the component received a Blur event (loses focus), problem was that the blur routine was still dispatching while the component was already removed. After looking for an option to wait for the routine to finish, I solved it in a nasty way:

 setTimeout(function(thisObj) { thisObj.dispose(); }, 200, this);  

that is, setting a timeout to let the routine finish, and then disposing it.
