about oncomplete attribute dynamic invoke el expression

[AndrewZhang]

in my company, we used richfaces before, in a4j:commandbutton we can set its oncomplete attribute with a js function that contains a el expression which can dynamicly get a argument through a backend bean mothod after ajax request we triggered by click it...like this oncomplete="addItem(#{beanAction.itemId})" evey time after ajax
request we can get a itemid for addItem function. I know i can workaround this problem with requestContext in using p:commndButton, like that oncomplet="additem(args.itemid)", so i just think aj4:commandbutton is a little more convenient for this situation.

You can either use RequestContext.addCallbackParam() to execute your scripts based on a condition;
