Hi, I got my navigation working great for my default community. Now, when I create a new community, the navigation gets completely replaced by the page structure in that community. I was wondering if there is a way to force the community-id (or whatever variable) so that the navigation.vm always puts the global nav on top? then I can add subnavigation for the specific community.

Here you go...this was written in liferay 6.1 CE GA1

Thanks Brian for youre code, it was very useful to our team.

Unfortunately it is not working on Liferay 6.1.1 GA2.
This is because in the new version they changed the com.liferay.portal.theme.RequestVars constructor: it now requires the VelocityContext as a parameter.
I was unable to retrive it from navigation.vm.

Did someone figured out how to make it work?

Thanks in advance
Daniele

Daniele,

I think you can use below code ,seems that it will work
1
2#set($velocityEngineUtil=$portal.getClass().forName('com.liferay.portal.kernel.velocity.VelocityEngineUtil'))
3#set($templateContext=$velocityEngineUtil.getWrappedStandardToolsContext())

before using $template ,please also verify the other arguments are available or not

1
2#set ($requestVars = $requestVarsConstructor.newInstance($request, $theme_display, $mainLayout.ancestorPlid, $mainLayout.ancestorLayoutId,$templateContext))

HI John,
thanks a million for you quick answer.
I tried your solution but it did not match my needs: it seems like the method 'velocityEngineUtil.getWrappedStandardToolsContext()' returns a sort of an empty context.

When calling $nav_item.icon() I get the following exception
12:57:13,942 ERROR [http-bio-8080-exec-10][LiferayMethodExceptionEventHandler:33] java.lang.NullPointerException
java.lang.NullPointerException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

at com.liferay.portal.theme.NavItem.icon(NavItem.java:144)
at sun.reflect.GeneratedMethodAccessor462.invoke(Unknown Source)
......


It looks like the WrappedStandardToolsContext does not set "velocityTaglib#layoutIcon"
(see com.liferay.portal.theme.NavItem.java:144)
