Known problems in XULRunner 1.9.2 h3. org.mozilla.interfaces.inIFlasher inIFlasher does not work on MacOS. It is needed to show a border around selected elements in VPE. *Workaround:* To show a border on MacOS the following style is used: "border: 2px solid COLOR_NAME !important". But the workaround has a drawback: if the selected elements has its own border, it is not visible. h3. draggesture event XULRunner does not fire 'draggesture' event on Linux. *Workaround:* Special button for Drag&Drop actions is used. Instead of listening to the 'draggesture' events, VPE listens to the 'mousedown' event on this button. h3. org.mozilla.interfaces.nsIDragService.invokeDragSession(...) The method invokeDragSession works differently on Windows and Linux. On Windows it exits *after* the session is ended. On Linux it exits *immediately*. The following snippet illustrates this: document.addEventListener("dragstart", new nsIDOMEventListener() {      nsISupports queryInterface(String uuid) {           return null;      }      void handleEvent(nsIDOMEvent event) {           nsIDragService dragService = (nsIDragService)                 Mozilla.getInstance().getServiceManager()                          .getServiceByContractID("(a)mozilla.org/widget/dragservice;1",                                    nsIDragService.NS_IDRAGSERVICE_IID);           System.out.println("BEFORE invokeDragSession");           dragService.invokeDragSession(node, transferables, null,                 nsIDragService.DRAGDROP_ACTION_MOVE                         | nsIDragService.DRAGDROP_ACTION_COPY                         | nsIDragService.DRAGDROP_ACTION_LINK);           System.out.println("AFTER invokeDragSession");      } }, false); document.addEventListener("dragend", new nsIDOMEventListener() {      nsISupports queryInterface(String uuid) {           return null;      }      void handleEvent(nsIDOMEvent event) {           System.out.println("dragend");      } }, false); document.addEventListener("dragover", new nsIDOMEventListener() {      nsISupports queryInterface(String uuid) {           return null;      }      void handleEvent(nsIDOMEvent event) {           System.out.println("dragover");      } }, false); *     Windows output:* *     Linux output:* -------------------------------------------------------------- Comment by going to Community [http://community.jboss.org/docs/DOC-15275] Create a new document in JBoss Tools Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=102&am...]
