OK, still can't get my custom navigation to work. I have 4 main tabs in my
application; 3 of the 4 are typical ERXNavigationMenu tabs, with 3 levels of
sub tabs. But one tab has so many subtabs that I want to display the entities
in a popup button and when the entity is selected, navigate to that entity's
query or pick page. I have that part working, but as soon as you click on any
action on the query or pick page, you are immediately logged out with no
exceptions thrown.
To do this, I've extended the ERXNavigationMenu to create MyNavigationMenu and
added a showDropDownMenu condition if there are 4 levels in the
NavigationState. In the rule file I've made the navigationState for those
entities, have 4 levels. For example:
60 : pageConfiguration like 'QueryBilling*' => navigationState =
"DataManagement.DMList.Billing.QueryBilling"
[com.webobjects.directtoweb.Assignment],
Here's my MyNavigationMenu:
Created a MyNavigationMenu component that extends ERXNavigationMenu and have
added MyNavigationMenu to my MenuHeader.html.
- In the html file, I've added:
<wo:if condition="$showDropDownMenu">
<div class="navDropDownMenu">
<wo:form>
<wo:AjaxObserveField action="$entityChanged" fullSubmit="$true"
updateContainerID="ContentWrapper">
<wo:popUpButton item="$aNavigationItem" list="$dropDownItems"
noSelectionString="Select One to Manage"
displayString="$aNavigationItem.displayName"
selection="$selectedNavigationItem" />
</wo:AjaxObserveField>
</wo:form>
</div>
</wo:if>
- This is the Java file:
public class MyNavigationMenu extends ERXNavigationMenu
{
public ERXNavigationItem selectedNavigationItem;
public NSArray _dropDownItems;
public MyNavigationMenu(WOContext context)
{
super(context);
_dropDownItems = null;
}
public ERXNavigationItem selectedNavigationItem() { return
selectedNavigationItem; }
public void setSelectedNavigationItem(ERXNavigationItem ni) {
selectedNavigationItem = ni; }
public NSArray dropDownItems() { return _dropDownItems; }
public void setDropDownItems(NSArray newDropDownItems) { _dropDownItems =
newDropDownItems; }
public void reset()
{
_dropDownItems = null;
super.reset();
}
@Override
public void setUpMenu()
{
super.setUpMenu();
if (menuLevelsToShow() >= 4 && dropDownItems() == null)
setDropDownItems(itemsForLevel(3));
}
public boolean showDropDownMenu()
{
return navigationState().stateAsString() != null &&
navigationState().state().count() >= 3 &&
_dropDownItems != null &&
_dropDownItems.count() > 0;
}
public WOActionResults entityChanged()
{
if (selectedNavigationItem != null)
{
String action = selectedNavigationItem.action();
action = action.substring(action.lastIndexOf(".") + 1);
NSArray<Method> methods = new
NSArray<Method>(((Session)session()).navController().getClass().getDeclaredMethods());
WOComponent nextPage = null;
Method m = null;
for (Method m1 : methods)
{
if (m1.getName().equals(action))
{
m = m1;
break;
}
}
if (m != null)
{
try
{
nextPage =
(WOComponent)m.invoke(((Session)session()).navController(), new Object[0]);
}
catch (Exception e)
{
log.debug(e.getMessage());
}
return (WOActionResults)nextPage;
}
}
return null;
}
}
NavigationMenu.plist section for this tab:
(
{
name = "Root";
children = "session.navController.mainTabs";
},
{
name = "DataManagement";
action = "session.navController.dataManagementAction";
displayName = "Data Management";
},
{
name = "DMList";
children = ("Billing", "CourseLength");
},
{
name = "Billing";
action = "session.navController.queryBillingAction";
children = ("QueryBilling", "CreateBilling");
},
{
name = "QueryBilling";
action = "session.navController.queryBillingAction";
},
{
name = "CreateBilling";
action = "session.navController.createBillingAction";
},
{
name = CourseLength;
children = ("PickCourseLength","CreateCourseLength");
action = "session.navController.pickCourseLengthAction";
displayName = "Course Length";
},
{
name = CreateCourseLength;
action = "session.navController.createCourseLengthAction";
displayName = "Add Course Length";
},
{
name = ListCourseLength;
action = "session.navController.listCourseLengthAction";
},
{
name = PickCourseLength;
action = "session.navController.pickCourseLengthAction";
displayName = "Course Lengths";
}
)
Any ideas on why this doesn't work? Or has someone already done this a better
way? I know I should probably have something in the navigationMenu.plist or
rule file to set showDropDownMenu instead of just adding a fourth level to the
navigationState, but once I learn how to create those custom flags, I'll do
that.
TIA,
Dawn

I have extended ERXNavigationMenu to create a submenu as a drop down list

to the list page. However, once I click on any navigation actions on the list
page, it immediately logs me out. What else do I need to set before I return
the list page?
I had hoped to come this week to WOWODC, but K12 was too cheap to send us and
they stalled so long in telling us that we weren't going, that the hotel was
booked and the airfares had risen dramatically. :( So Kieran will have to drink
a few beers for me!
