hello,
In my theme i have a requirement that one of the navigation links will contain the list that will be dynamically populated after querying the database.
Can we make a database call in navigation.vm ?

I am sorry, you have to include the javascript code(onclick) for calling the database in your portal_normal.vm of your theme..
You just google javascript code for the same, u will get it..

Hi,
Please check the following link

I think editing the velocityvariable class will give you access to your database and then you can access the variable with a $ in your init-custom.vm
I didnt tried anyways but that can be a possible solution(an idea).

Yes, although you shouldn't do things this way.

Navigation.vm is a velocity script, and tweaking the velocity context to include necessary stuff to run the query would not be good.

Instead you should wrap the logic into a Spring bean. Register the bean in the portal's Spring context, then use $utilLocator.findUtil("my spring bean") to get access to the spring bean in navigation.vm, call the bean, and handle the results.
