> I am having this problem for a long time and lost any hope of getting a decent answer in any forum:
> It seems like JSF does not give any solution to initial state problem.
> A simple example:
> I want to show a simple table that is being updated according to several filters.
> The table should be shown with initial data according to filters selections.
> The actions that I am doing are:
> 1) To show initially the table, on the backing bean constructor I am loading the table data.
> 2) On any "valueChange" of every filter I want to load the new data of the table also, so I load the data again.
> This causes the data of the table to be loaded twice: once in the constructor and second in the value change listener method.
> This problem happens in many variations many times in JSF. Is there a way of initializing data properly ?
> For example, I would expect that in addition to the constructor there will be 2 additional methods:
> 1) init() - Will be called when screen first loads.
> 2) reinit() - Will be called when screen is reloaded.
> Am I missing here something ?  Or there is a solid agreed way of solving the initial state term in JSF.
> By the way, I have to initialize data dynamically and not using managed properties.
