Enrique,

>I have two combos, the list in the second combo depend of the first combo's value. So, how or where especify the parameter of the view displayed in sencon combo?, is the parameter like public variable?, and the requery command must be to the combo or to buzobj?

There are a few ways to accomplish this. Much depends on how you have set up the comboboxes.

First of all, are the comboboxes located on the same page of a pageframe or directly on a form...or are they on different pages of a pageframe?

How did you load the view that is the RowSource of the second combobox? Is it the "InitialSelectedAlias" of a business object or did you load it as a secondary cursor in a business object's data environment?

Regards,
