Thanks again for your help.
I could not use "id" because in ExtJS generated ID properties are dynamic and more often than not, non-repeatable. In our current app, many of the page items I need to locate have varying properties which have some kind of uniqueness, so I need to be flexible about which property I use to find something, but I can almost never rely on IDs.
When I need to generate, then click on list items generated in real time, the IDs ALWAYS change so cannot map them.
I hope to let you know soon if this worked.
