Hi there, I have a ScrollPanel wrapped around a FlexTable. When the end of the FlexTable is reached, new Items are loaded from the server.
My Problem: when the end of the currently available list is reached, onScroll() triggers a RPC-request, which calls a Servlet, which returns more results (adds them to the table etc.). For some reason this RPC-request is called TWICE in IE, while only being called once in Firefox - which is the correct behavior. I've ensured that the ScrollPanel is created only once and that it adds the ScrollHandler only once (addScrollHandler is called only once!). I am totally puzzled as to why it makes the RPC-call twice... http://gyazo.com/3e9765027df79287d0c0b52f303fc2d7.png (resulting table, displayed in IE8) http://gyazo.com/ed319e73e2816034bb35cc7c43ef8858.png (resulting table, displayed in FF) Some rows are there twice, because they aren't totally equal (different char-...). However: as you can see in the IE8 screenshot the "animal bone" item is ABSOLUTELY the same - which is wrong behavior. In Firefox you can see, that there is only one "animal bone" item which belongs to char268472623. In the console window I can see that IE triggers the RPC twice. I tried to check inside the RPC-request if it is called again or not, but it seems that these calls are made at the same time - so one doesn't know the other one is made. I've tried to make a small example. I created a new project, which contained an EntryPoint, a ScrollPanel, a FlexTable and a ScrollHandler. However: this example did work flawlessly. Please help me fix this - I'll post any code you need. Here's what my onScroll-method looks like: public void onScroll(ScrollEvent event) { //System.out.println("scrolling..."); //System.out.println("itemScroller: " + (itemScroller.getScrollPosition() + itemScroller.getOffsetHeight())); //System.out.println("itemTable: " + itemTable.getOffsetHeight()); if (itemScroller.getScrollPosition() + itemScroller.getOffsetHeight() > itemTable.getOffsetHeight()) { //System.out.println("triggered!"); loadCharacterItems(DataKeeper.getItemsCount(), 15); } } I left the System.out.println-stuff there so you can see what I already tried to compare. Here's what those System.out.println()-calls produce: // IE8 scrolling... itemScroller: 411 itemTable: 746 scrolling... itemScroller: 427 itemTable: 746 scrolling... itemScroller: 444 itemTable: 746 scrolling... itemScroller: 461 itemTable: 746 scrolling... itemScroller: 461 itemTable: 746 scrolling... itemScroller: 471 itemTable: 746 scrolling... itemScroller: 487 itemTable: 746 scrolling... itemScroller: 504 itemTable: 746 scrolling... itemScroller: 521 itemTable: 746 scrolling... itemScroller: 521 itemTable: 746 scrolling... itemScroller: 604 itemTable: 746 scrolling... itemScroller: 683 itemTable: 746 scrolling... itemScroller: 747 itemTable: 746 triggered! scrolling... itemScroller: 747 itemTable: 746 triggered! 200 - POST /odrop/RPCBelongingsService (192.168.56.1) 721 bytes 200 - POST /odrop/RPCBelongingsService (192.168.56.1) 721 bytes // FF scrolling... itemScroller: 455 itemTable: 506 scrolling... itemScroller: 507 itemTable: 506 triggered! 200 - POST /odrop/RPCBelongingsService (192.168.56.1) 721 bytes Any help is greatly appreciated!
