Re: [jsr-314-open-mirror] [jsr-314-open] Fix UIData state saving model (issue 153)

Later, when UIData.setRowIndex is called we use that information to restore the initial state first of each component and then apply the delta. Right now, when markInitialState() is called on the table, all children inside the table has been already marked, so we need to call clearInitialState() on all children, then call saveState() to get the required information and then call again markInitialState(). I tried to find an alternative to not traverse the tree calling markInitialState() as suggested, and use something different like a listener to PostAddToViewEvent, but I found that it will not work, because it is possible to create a tag that add some attached object to a component on this event (for example: t:autoScrollPage).
