You probably use some AsyncTasks to load the dataset and it is hard to determine which task will be the last to finish. And only after that last task, when the whole dataset is complete you could call OnPageSelected, because it is doing a flush on the UI over the whole dataset.

Instead of calling the OnPageSelected-function manually when the page is loaded the first time, rather build up the UI step by step the "normal"-way. Later on, when the user changes the page, the dataset should be complete and it is save to let the update been made in the OnPageSelected-function.
