Using Arcane to set CIMPrimitiveOverride with if statement

ChaosSteve — Thu, 02 Jan 2025 14:32:08 GMT

I am working with primitive overrides to change the image URL of for a feature. I want to set the CIMPictureMarker based on an attribute. Eventually my if statement will grow more complex, but I am starting with a basic change out of the image URL.

I have created a script tag in my HTML to return a different image based on the value of an attribute

<script type="text/javascript" id="serviceTag">
        if($feature.open){
            return "https://myURL/order-green.png"
        }else {
            return "https://myURL/order-red.png"
        }
</script>

Then I reference that element and put it into my valueExpressionInfo

const serviceArcade = document.getElementById("serviceTag").text;
const serviceOrderRenderer =  {
    type: "simple",
        symbol: new CIMSymbol({
        data: {
            type: 'CIMSymbolReference',
            primitiveOverrides: [
                {
                    type: 'CIMPrimitiveOverride',
                    primitiveName: 'imageColorOverride',
                    propertyName: 'url',
                    valueExpressionInfo: {
                        type: 'CIMExpressionInfo',
                        expression: serviceArcade,
                        returnType: 'Default',
                    },
                }
            ],
            symbol: {
                type: 'CIMPointSymbol',
                primativeName: "imageMarker",
                symbolLayers: [
                    {
                        type: "CIMPictureMarker",
                        enable: true,
                        primitiveName: 'imageColorOverride',
                    },
                ],
            },
        }
    })
}

It gives me an errors saying ParsingError: Unexpected identifier. Why does it say it cant parse an if statement?

Hey @ChaosSteve

It may be because the if statements in Arcade are slightly different, would replacing your if statement with this be fruitful?

The Arcade samples use the "text/plain" attribute generally with inline scripts and the "text/javascript" attribute with external .js files. Does this fix your parsing error?

It looks like an attribute cannot be a boolean, so I have it set to a string. My new code is

<script type="text/plain" id="serviceOrderTag">
    return IIf($feature.open === "true", 'https://myURL/order-green.png',
        'https://myURL/order-red.png');
</script>

This is working

This was also part of the issue

To follow up on this I am trying to add a string builder. It tells me a comma is expected on this formatting. Not sure if there is an issue with checking for null or if arcane has a different way to check

return IIf($feature.ageCategory != null, 'url.com/order-' + $feature.age + '.png', '//url/order-0.png'

Missing ending bracket. Fixed
