Groovy: How to access objects with Id tag?

I have the following Groovy+SwingBuilder code.

In one panel I generate checkboxes and in another panel I want to access the values of the checkboxes. The code looks basically likes this:

def optionsmap = [ foo : "value_foo", bar : "value_bar"]

SwingBuilder.build()     
{
   frame(title:'demo1', size:[400,700], visible:true, defaultCloseOperation:WC.EXIT_ON_CLOSE) {                
      gridLayout(rows: 1, cols: 2)

      panel(id:'optionPanel', constraints:java.awt.BorderLayout.CENTER) {                        
         gridLayout(rows: 5, cols: 1)                 
         myGroup = buttonGroup();    
         for (entry in optionsmap)
         {         
           checkBox(id: entry.key,   text: entry.value        )                  
         }            
      }

      panel(constraints:java.awt.BorderLayout.WEST) {   

         button ('Show values', actionPerformed: {           
         for (entry in optionsmap)
         {
            println (entry.key as Class).text            
         }           
       })                
    }
  }  
}

optionsmap is a map with (id, text) pairs that can be extended.

When I press show values I get an error message:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'foo' with class 'java.lang.String' to class 'java.lang.Class'

How could I access the checkboxes for my action in the second panel by using the checkbox ids from optionsmap?

What, exactly, do you mean by "does not work"? Does it crash? Does it, perhaps, only output the ones that are checked? Are they all non-selected? How are you binding the data in the previous panel's form? Please be more complete. - billjamesdev

The solution to access variables from the map is like this:


                 for (entry in optionsmap)
                 {
                      if (variables[entry.key].selected)
                          println variables[entry.key].text
         }
