how enable itemChanged() in ECM MB callout

tvguide_dev

We're using a ECM dialog call from TeamSite to MediaBin and back. We need to fire some custom API calls after the MediaBin window closes.

It seems the fields in the DCR don't get an itemChanged message when the child window closes. I found the following script in the source child (mediabin) window:

// TODO: Fire an onItemChanged event.
//var eventRegistry = window.opener.top._dcWin.IWDCEventRegistry;
//eventRegistry.fireEvent("onItemChange", item);
//window.opener.top.api.iw_callHandler("onItemChange", item);

It seems the itemChnaged call has been specifically disabled. I located this code in \TeamSite\httpd\webapps\content_center\WEB-INF\jspc\com\interwoven\ecmconnector\mediabin\browser_jsp.java and uncommented the lines in question, but this did not help. I suspect this file needs to get recompiled.

How do I do this - or is there another way to get the itemChanged callback enabled?

thanks in advance...
