I am Eugene's co-worker. The entire code block would be unreasonable as it contains alot of business rules that have nothing to do with the technical issue. The basic code summary is this:
Inside a re-usable panel orgPanel: final DropDownChoice<StructureL> structureDropDown = new DropDownChoice<StructureL>("StructureL", StructureLList, structureRenderer); structureDropDown.add(new AjaxFormComponentUpdatingBehavior("onchange") { protected void onUpdate(AjaxRequestTarget target) { //WHOLE lotta code...I'll cut down to the parts that affect the target. //Note that alot of this is conditional, and different combinations happen on different conditions choiceAppl.setChoices(optionsApps); target.addComponent(choiceAppl); target.appendJavascript("resetWidth();"); target.appendJavascript("setWidth();"); [...] target.addComponent(wmc1.setVisible(isVisibleAll)); target.addComponent(wmc2.setVisible(isVisible)); target.addComponent(wmc3.setVisible(isVisibleAll)); target.addComponent(wmc4.setVisible(isVisible)); target.addComponent(structureDropDown); target.appendJavascript("resetWidth();"); target.appendJavascript("setWidth();"); } } Inside a different re-usable panel that is seeking to use the panel but need to do something extra onchange: final DropDownChoice struct = (DropDownChoice) orgPanel.get("StructureL"); struct.add(new AjaxFormComponentUpdatingBehavior("onchange") { private static final long serialVersionUID = 1L; @Override protected void onUpdate(AjaxRequestTarget target) { onOfficeChange(target, struct, org1, org2, org3, org4); } }); [...] private void onOfficeChange(AjaxRequestTarget target, DropDownChoice struct, DropDownChoice org1, DropDownChoice org2, DropDownChoice org3, DropDownChoice org4) { List<String> users = loadUsersByOfficeInfo(target, struct.getInput(), org1.getInput(), org2.getInput(), org3.getInput(), org4.getInput()); if(users != null) { listUsers.setChoices(users); target.addComponent(listUsers); listUsersFromOffice.setChoices(users); target.addComponent(listUsersFromOffice); } } Note that the list* controls are both ListMultipleChoice and the structure control are others within orgPanel are DropDownChoices. The behavior is that the panel within the panel in my page works fine if i don't add a second AjaxFormComponentUpdatingBehavior to the same event. When I add my second event, the second works perfectly. But the original is never called (confirmed by both breakpoint and print statement), breaking the behavior of that component. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Adding-to-the-existing-AjaxBehavior-of-a-component-tp4657400p4657489.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
