Any of those help You can use with session scope.
code :
<g:set var="foo" value="bar" scope="session" />
<g:set var="someService" bean="someService"/>
<g:set var="foo" value="${someService.makeDBCall()}" scope="session" />

Setting global variables and accessing them in Grails controllers

will help you Your controllers should stay stateless. Controllers are instantiated at each action request, so your member variable myList will be thrown away between actions. If you define it static, it will be shared by all instances of MyController.
If you define myList static, all clients accessing your controller will get the same result. If that's what you want, your list should probably be stored through domain objects in your database (see chapter 5 of Grails documentation, Object Relational Mapping).

This might help you You can use the Set-Variable cmdlet. Passing $global:var3 sends the value of $var3, which is not what you want. You want to send the name.
code :
$global:var1 = $null

function foo ($a, $b, $varName)
{
   Set-Variable -Name $varName -Value ($a + $b) -Scope Global
}

foo 1 2 var1
$global:var1 = $null

function ComputeNewValue ($a, $b)
{
   $a + $b
}

$global:var1 = ComputeNewValue 1 2

To fix the issue you can do You could use a Service for this task. Service is a singleton, so it will be alive all the time. And it's much easier to access from other parts of app. To prepare data on application startup, you can implements InitializingBean.
Foe example:
code :
class MyCacheService implements InitializingBean {

  Map cache

  void afterPropertiesSet() {
     cache = [
        a: 1,
        b: 2,
        // .....
     ]
  }
}

To fix the issue you can do Okay I found a solution.
Every controller implemented a main layout for resources etc via :
code :
<meta name="layout" content="main"/>
<g:set var="config" bean="configurationService"/>
<script>
    var shouldRedirect = ${!config.hasBeenConfigured()};

    if(shouldRedirect && window.location.href.indexOf("AppConfiguration") == -1)
    {
        window.location.href = window.location.origin + "/AppConfiguration/index";
    }
</script>
class ConfigurationService {

    def hasBeenConfigured()
    {
        return AppConfiguration.instance.hasBeenConfigured;

    }

    def getApplicationName()
    {
        return AppConfiguration.instance.applicationName;
    }
}
