Grails returning value from controller to gsp

I have been searching on how to return an integer value from controller to the gsp. I tried using this:

    def test(){
        def val = 1;
        return val;
    }

but it does not work. Please help.

The return statement is used to return values from services to controllers. If you want to pass values from the controller to gsp, use:

[variableNameInGSP : valueToBeReturned]

Add this code to your controller:

def test(){
    def v = 10
    render view:'test.gsp', model:[v:v]
   }

Then, access the value from your test.gsp by "${v}" Note that the render view is optional for test.gsp, i've written it only for demo purpose.. (i.e change the gsp filename).

Hope it helps.

Try 

 def test(){
    def val = 1;
    [val:val]
   }
