JSF - How to filter data

[Gregg Wachter]

Here's my JSF question.
I have a Model connected to my jsp via value="#{getAlerts} but also have buttons which allow the user to set the viewType to either "Watch List", "Raised" or "All". When, the viewType changes via a button push the displayed results don't change. Instead, it requires two button pushes to get the results I'm expecting. Note: the data filtering occurs inside the getAlerts() method as it checks for viewType and returns a filtered list.
Is this due to LifeCycle processing in JSF or is there a bug? Is the approach for filtering in the getXXX() correct or would it be better to set some indicator on the UIData rows and modify a renderer to skip rows with isFiltered() = true? Seems like messing with a renderer for such a simple task mught be overkill.
