Hi,

I am trying GoJS to see if it can be usefull in a project.

I can't find a way to dynamicaly generate the "text" property of a "PanelExpanderButton" so that it will be linked to a Panel "name" also dynamically generate. The value "tube_id" is unique.

Here is a part of the model:

            itemTemplate:
                GOJS(go.Panel, "Table",{ column: 0 },
                    GOJS(go.TextBlock, new go.Binding("text", "tube"),{column: 0,margin: 4}),
                    GOJS("PanelExpanderButton", new go.Binding("text", "tube_id"),{column: 1}),
                    GOJS(go.Panel, "Vertical",new go.Binding("name", "tube_id"),{
                        padding: 2,
                        itemTemplate: fieldTemplate,
                        row : 1,
                        column: 0,
                        columnSpan: 2
                    },
                    new go.Binding("itemArray", "fibers"))
                )

Here are the message that I got from the console:

Binding error: missing GraphObject named COLLAPSIBLE in Panel(Panel.Table)#19161
Binding error: cannot modify GraphObject.name on Panel(Panel.Vertical)#19168
Binding error: undefined target property: text on Panel(Panel.Auto)#19260

Any ideas ?

Thank you
