After using geometryString inside an element of a node, fill not working on that

In a node I have a table element, inside it, I have a shape geometry and on the geometry fill doesnt work.
this.goMake(go.Shape, { geometryString= something,
fill: “red”,// not working
strokeWidth: 1, // good works
stroke: “red”, // good works

Read about geometry path string syntax at GoJS Geometry Path Strings -- Northwoods Software.

Basically you need to declare whether the geometry is filled or not. Either prefix the string with “F” or call Geometry | GoJS API. Or set the Shape.geometry by calling Geometry | GoJS API with its second argument true.
