I have a dynamic action that is fired from an onclick on a column in an IR - the (serialised) action uses PL/SQL to build an Anychart XML and then opens a Jquery dialog (floating) window/region that renders the graph. (Apex 4.2..2.x)
In some cases it takes several seconds for the PL/SQL part to execute - which means no visual cues to the web user that the page is busy processing. Instead of hacking custom Jquery regions for spinner images and the like, I would rather stick to standard Apex functionality. So what would the proper way be to deal with this?
Any pointers/doc references will be appreciated. Thanks.
