Hi, I have the following browser: | browser | browser := GLMTabulator new. browser row: [ :r | r column: #one; column: #two]; row: #three. browser transmit to: #one; andShow: [:a | a title: 'One'. a list display: [ #('Something 1' 'Something 2' 'Something 3' 'Something 4')]; selectionAct: [:list | (list pane port: #customSelection) value: 1 ] entitled: 'Open new panel' ]. browser transmit from: #one; to: #two; andShow: [:a | a title: 'Two'. a list display: [ #('A' 'B' 'C' 'D') ] ]. browser transmit from: #two; to: #three; andShow: [:a | a title: 'Information'. a text display:[ :x | 'Information related to ',x asString ] . ]. browser transmit to: #three; from: #one port:#customSelection;andShow: [:a | a title: 'Three'. a list display: [#('A' 'B' 'C' 'D')] ]. browser openOn: 1. When a value of the list of the pane "two" is selected a new pane is open in #three. Also, when the action of the pop-up menu of the pane #one is selected, a new pane is open in #three. My problem is that the new pane opened after clicking in the pop-up menu is only shown the first time that it is called. That is, if I click in the menu, then I click in an element of the pane #two and finally I click again in the menu action the pane #three is not shown this time. I'm doing something wrong? I can't understand why this happens. Thanks!
