stuck in Glamour-Merlin flow and update doesn't help

Scenario : I have an EyeSee chart that is updated from user input. 

Problem: The EyeSee chart does not update. There are two methods (AFAIK) to update glamour browser pane and its contents: explicitly send update message to the pane or new transmission to the port of the pane to be updated. Now, the first method does not work for EyeSee (may be a bug, i suggested a fix yesterday). The second method requires that transmissions are triggered but since Merlin is outside Glamour, I have to fake a transmission on a dummy port (I tried that but when I execute my browser, the dummy port is nil).

I spent several hours looking into ports and their transmissions but couldn't obtain a workable solution for my problem. Here is a mock executable code to see what I am trying to achieve.

| browser aModel myColor|

browser := GLMDashboard new.

browser title: 'Customizable EyeSee Chart Example'.

browser addPaneNamed: #chart1 extent: 600@600.

myColor := Color green.

browser transmit 

to: #chart1; 

  andShow: [ :a |

      a eyesee

title: 'Sample bar chart';

diagram: [:renderer :x |

                     (renderer kiviat)

borderWidth: 1;

radius: 150;

models: {#(8 10 1). #(7 2 10). #(3 10 8)};

metrics: {#first. #second. #last. [ :each | each first + 2]};

maxs: {[ :model | 10]. [ :model | 10]. [ :model | 10]. [ :model | 10].};

mins: {[ :model | 1]. [ :model | 1]. [ :model | 1]. [ :model | 1]};

roundedBorder: true;

backgroundColor: myColor;

displayLegend: true;

kiviatBackground: true;

useColors: ESAbstractDiagram strongColorsTransparent];

act: [

| wizardControl  wizardPane1  dropListPart|

wizardControl := WizardControl new.

wizardControl renderer: MerlinMorphicWizardRenderer new.

wizardPane1 := WizardSinglePane new.

dropListPart := DropListPart new list: #(red black green); yourself.

wizardPane1 row: dropListPart associatedTo: #color.

wizardControl addPane: wizardPane1.

wizardControl atEndDo: [ :aDictionaryOfOutputs | 

myColor := aDictionaryOfOutputs at: #color. 

(browser paneNamed: #chart1) update ].

wizardControl open. 

] entitled: 'Parameterize Color'.

].

browser openOn: #(1 2 3 4 5 6 7 8). "can't put color in the input model"

Can you please have a look and see if I am missing something?
