Data Utility Best Practice Recommendations

We use a data utility to render Boolean attributes as check boxes in a document create page.   The default value for all these Boolean attributes is no (unchecked) . In the same create page we have an attribute with a conditional constraint (select a certain value in the drop down list and another attribute in the page is set to Required).   If a user makes selections for the Boolean attributes (checks one or more of the boxes) and then make a change to the conditional constraint attribute, the page is refreshed, and the Boolean attributes are unchecked (reset to default value).   Is there a best practice for configuring this data utility so the Booleans remain as-is when the conditional constraint attribute is updated?
