I want to store/restore the column width, sort-order and column visibility from a Grid. After some searching around i found some answers which describe StateManager and applyState. For example a thread on 16 Oct 2012;
"How to work with StateManager gxt 3"
Within the 'best answer' Colin already switches from a 'standard' to a custom technique;
Indeed this seems argumentative to me; i need an StateHandler which saves the Grid state to Google App Engine, and with a custom applyState() i could restore this state. But this seems a custom home made solution... Isn't there a standard procedure for this in the GXT3 framework? (like the approach with the loader/proxy from the Grid)And instead of this last step, consider just extending the AbstractStateHandler, and implementing your own applyState() method to modify the object that has this state. Build any handlers required then, to modify the contents of getObject() - notice that you can't replace the instance (in short: autobeans dont really work well like that), but you can modify any other object in it.
