Multiple Dataloads on Tabchange

Hi,

since we have implemented Lazyloading (from walkthrough) for our Tab-based-template, we get several multiple loadings of all visited tabs. The logic loads all controllers of all visited tabs together. Due to the reason, we call several Stored Procedures with ajax, we will load all Stored Procedures, when we visited all Tabs once, on every Tabchange. Sure, this will led into a massiv performance-problem. May anyone is able to help us? What do you need to verfiy this?

Thanks in advance!
