How do I populate a 'select' box in the config: section of a plugin using args.projects?

[Peter Goudman]

Within the Field+Definintions page.

https://developer.atlassian.com/display/GADGETS/Field+Definitions

It reads,

options:[

{ /* These options are hard-coded but could easily be the results of an AJAX call

(E.g. args.projects) or be calculated at run time

Can anyone tell me how its done, been on this problem for two days now.

Okay I figured it out. Here is my code to display a prepopulated list box from a dynamic source (JSON) format, it displays the listbox in the config cycle of a JIRA gadget.

/// In gadget.xml config section

config: {
      descriptor: function (args)
      {
          var gadget = this;
          gadgets.window.setTitle("Choose Baseline...");
          
          // A select box that is populated by the AJAX JSON call in the args: section below
          var baselineOne = { 
          		id: "BL1", 
          		userpref: "Testing", 
          		type: "select", 
          		label: "Baseline One", 
          		description: "Select baseline one...", 
          		options:  args.baselines	
          };
          
          return  {
              fields: [
                  
                  baselineOne
              ]
          };
      },
      args: function()
      {		// Call AJAX and return JSON format.  The REST services class returns 
          return [
          {
             key: "baselines",
             ajaxOptions:  "/rest/baseline-gadget/1.0/baselinecomparison/getBaselines.json"
	
          }
	
          ];
      }()
}, // End of config section

// The Java method to return the data follows...

	  @GET
    @AnonymousAllowed
    @Produces({MediaType.APPLICATION_JSON})
    @Path ("/getBaselines")
    public Response getBaselines(@QueryParam ("projectId") String projectIdString){
    	
    	Collection<ABaseline> baselines =
    		new ArrayList<ABaseline>();
 
    	for(int i = 0; i < 10; i++){
    		ABaseline abaseline = 
    			new ABaseline("https://<CONFIDENTIAL DATA REMOVED>" + 
    				(i+1) + "_Baseline", "" + (i+1));
    				
    		baselines.add(abaseline);
    	}
    	
    	return Response.ok(baselines).cacheControl(null).build();
    }
