I'd like to change the width of the frame outline of certain mil2525d symbols via dictionary script. The symbol with key 0_101_0 is defined like so:

{
"type": "CIMPointSymbol",
"symbolLayers": [
{
"type": "CIMVectorMarker",
"enable": true,
"anchorPointUnits": "Relative",
"dominantSizeAxis3D": "Z",
"size": 64,
"billboardMode3D": "FaceNearPlane",
"frame": {
"xmin": 0,
"ymin": 0,
"xmax": 612,
"ymax": 792
},
"markerGraphics": [
{
"type": "CIMMarkerGraphic",
"geometry": {
"rings": [
[
[
391,
278
],
...
]
],
"spatialReference": {
"wkid": null
}
},
"symbol": {
"type": "CIMPolygonSymbol",
"symbolLayers": [
{
"type": "CIMSolidFill",
"enable": true,
"primitiveName": "frame_fill",
"color": [
255,
255,
128,
255
]
}
]
}
},
{
"type": "CIMMarkerGraphic",
"geometry": {
"paths": [
[
[
391,
278
],
...
]
],
"spatialReference": {
"wkid": null
}
},
"symbol": {
"type": "CIMPolygonSymbol",
"symbolLayers": [
{
"type": "CIMSolidStroke",
"enable": true,
"primitiveName": "frame_outline",
"capStyle": "Butt",
"joinStyle": "Miter",
"lineStyle3D": "Strip",
"miterLimit": 10,
"width": 5,
"color": [
0,
0,
0,
255
]
}
]
}
}
],
"scaleSymbolsProportionally": true,
"respectFrame": true
}
],
"haloSize": 1,
"scaleX": 1,
"angleAlignment": "Display"
}
Using the primitive name `frame_outline` I should be able to change the width of the rendered frame outline. When I change the width in this JSON then the new width is rendered. However, when I want to do this in the dictionary script using a primitive override
`keys += ';po:frame_outline|Width|100';`
The returned keys from the dictionary script looks like
`0_101_0;po:frame_fill|Color|RGBA(0,0,0,0);po:frame_outline|Color|#FF00FF;po:frame_outline|Width|100;...`
However, the width of the rendered frame outline is still the original width...
Changing the color of the frame_outline works though with following script
`keys += ';po:frame_outline|Color|#00FF00';`
This results in the correct color applied to the frame outline.
Why does it not work with the frame_outline width? Is there no way to change the width of the frame_outline via the dictionary script?
Many thanks!
