| preserve | false | true | java.lang.String | By default, the context is stored in session. When preserve is "true", when dynamically switching the "resource" to a second context, the old context is saved. When switching back to the first context, it is loaded from session and preserved in the same state where it was left, i.e., zoomed to a certain location. Note that saving contexts takes up memory. When preserve is "false", old contexts are not maintained in session after a new one is specified. If you do not need to preserve contexts or want to minimize memory usage, set preserve to "false". |
