Hi Everybody, I have identified the memory consumption problem within the custom ItemRenderer. This IR is derived from UIComponent and besides other elements has 3 Image members to display 3 possible icons. The grid has around 200 elements, so 200 IRs are created at the startup. Each IR creates 3 Images in createChildren() method with source = null. Source is set in the commitProperties() method, when we know the data. In reality only 10-15 IRs are displaying icons, the rest are just waisting the space (600 instances of Image consumes aroung 700Kb according to Profiler).
My question is how can I improve the efficiency of this IR? Is this possible to create Image instances on demand, not in the createChildren() method? I tried to create and destroy Images in commitProperties() according to data, but then I bumped into the problem that updateDisplayList() for the IR could be called with inconsistent data. I.e. data says that we need icons, but the the Image objects is null, they have not been created yet by commitProperties()/set data() for this instance. Is this a recycling feature that the order of commitProperties()/updateDIsplayList() are not guaranteed? Or I have overseen something? Thanks in advance! Regards, Dmitri.
