A way I try to cut out duplicate mapped objects, like navigation links, is by having a parent page object wherein the URL consists of only the official name of the site capped with *s. I map all of my navication links to this page. However, when recording, Test complete will map every object under this one page object.
Therefore, it would be nice if there was an objtion to set this object to be locked. Namely, the object is set so that children can only be added to it manually and not automatically.
