hi,damianharvey my trick is , first create grid object with a "createGrid(data)" function, then use js:function to get collection from server and transfer it into "data",after that i use js:function "oncomplete" to call "createGrid(data)" to build the grid. yes, i know js:Function is a very cheep way, :) but so far i didnot see any problem with xhtml and ajax4jsf filters.
