t:savestate question

[Tom Butler]

Within .jsp page I use t:saveState to save the backing bean. <t:saveState value="#{searchispbean}" />   t:saveState works to some degree, because when I remove it, t:datascroller can not display the datamodel (property on backing bean) when I scroll from the first page to the second page - with t:saveState enabled, this works.   However, when I leave the page with the t:saveState to another page, and then come back, the backing bean data has not been saved.     The backing bean does implement the Serializable interface (the only addition I have made to the class is adding the “implements Serializable” on the class definition – I did not add a serialVersionUID variable or anything else?): public class SearchIspBean extends SortableList implements Serializable  {….}   Any suggestions?
