[coldbox:4117] Popup window

I am trying to allow my users to edit a item in a order by clicking on
a link that would popup a window of that product on that order.
However it wants to put the "##" in the base url and refreshes that
window while the other window is up. What do I need to do to avoid
that page being refreshed? I am using Ajax to populate the shopping

Return false in the onclick= handler so that the link is not actioned:

<a href="" onclick="doWhatever(); return false;">popup</a>
