The best place to ask programming/development questions, imo. UPDATE: stackoverflow is the *worst* place to *ask* questions (if your first question/comment doesn't get any up-rating/response, then u can't ask anymore questions--ridiculously unrealistic), but a great reference for finding answers.

primefaces - show p:modalPanel from java backing bean / controller class and update specific id or collection of id strings

here's how you show a p:modalPanel from a java backing bean call:
org.primefaces.context.RequestContext.getCurrentInstance().execute("myModalPanelWV.show()");

"modalPanelWV" is the widgetVar value, e.g.:
<p:modalPanel id="myModalPanel" widgetVar="myModalPanelWV" ...

update an id from backing bean:
org.primefaces.context.RequestContext.getCurrentInstance().update("growl");

OR update a Collection<String> of IDs:
org.primefaces.context.RequestContext.getCurrentInstance().update(myCollectionOfStringIds);
