Values are not assigned if object parameters are changed after private method call in grails 2.2.4

Question

I have a method which calls private method. This method returns model. Once it is returned, I change some object values and render it. On jsp when I print value of 'message' then I do not get that value. Here is the code

def model = myMeth();
model.objkey.message = 'check message'
render(view: "index", model: model)

private method

private def myMeth() {
.....
    [objkey: objvalue]
}

& gsp

<div class="message">${objkey?.message}</div>

But if I add value to message in private method before return then it's value is printed on gsp.

This is the private method which prints value in gsp

private def myMeth() {
    .....
  objvalue.message = 'check message'
  [objkey: objvalue]
}

This used to work well in grails 1.3.7 but why does this happen in grails 2.2.4

Answer 1

This works as expected in 2.2.4 with the below setup hitting index action. Is this the way you have yours set up?

//controller
def index(){
    def model = myMethod()
    model.objectKey.message = 'check message'
    render view: "index", model: model
}

private def myMethod(){
    def objectVal = [:]

    [objectKey: objectVal]
}

//grails-app/views/<controllerName>/index.gsp
<div>${objectKey?.message}</div> //renders appropriate message
