I have same issue which I cannot solve for a while period. I have rich:tabPanel with 4 tabs and every tab has its own rich:dataTable. If I trigger whatever action on that tabPanel and that action has nothing with tables, in sense of data dependencies, tabPanel always render all 4 tables (in fact calls bean's methods in the background, which on their side trigger select queries), so on every actions I have 4 redundant select queries.
Can anyone help, because it is very urgent??
