Sling AEM / Model / Retrieve item text not value

Question

I have an AEM site. My front-end content.xml has a select list of different color options to pick from:

<items jcr:primaryType="nt:unstructured">
    <colors
        jcr:primaryType="nt:unstructured"
        sling:resourceType="granite/ui/components/coral/foundation/form/select"
        fieldLabel="Select a Color"
        name="./colors">
            <items jcr:primaryType="nt:unstructured">
                <blue
                    jcr:primaryType="nt:unstructured"
                    text="Blue"
                    value="bl blue"/>
                <green
                    jcr:primaryType="nt:unstructured"
                    text="Green"
                    value="gr green"/>....

My model looks something like:

@Model(adaptables=Resource.class)
public class Color{

    @Inject @Named("colors") @Optional
    private String cssClass ;

    @Inject @Named("colors.text") @Optional //This is not working
    private String label;

    public String getCssClass() {
        return cssClass;
    }

    public String getLabel() {
        return label;
    }

    public void setCssClass(String cssClass) {
        this.cssClass = cssClass;
    }

    public void setLabel(String label) {
        this.label = label;
    }
}

This code will return the cssClass string as either "bl blue" or "gr green" depending on what the user selected.

My question is how do I get the label string to return "Blue" or "Green" (aka the text attribute of the selected color item)?

Thanks!

It is not possible to get the label, as only the value of the dropdown gets saved in CRX when the author selects a color. The label is only used when rendering the dialog and not part of the actual values saved. You may need to find a way to either save the label as well when the option is selected, or create a Map of labels and use the selected color the key to find the corresponding label. — rakhi4110, Feb 01 '19 at 00:32

While what you are asking is not possible, because the value is the only thing that will be stored in JCR (as @rakhi4110 mentioned), you could still add the text value in the value attribute and parse it in the sling model.

Here is one way you can do it:

<items jcr:primaryType="nt:unstructured">
    <colors
        jcr:primaryType="nt:unstructured"
        sling:resourceType="granite/ui/components/coral/foundation/form/select"
        fieldLabel="Select a Color"
        name="./colors">
            <items jcr:primaryType="nt:unstructured">
                <blue
                    jcr:primaryType="nt:unstructured"
                    text="Blue"
                    value="Blue:bl blue"/>
                <green
                    jcr:primaryType="nt:unstructured"
                    text="Green"
                    value="Green:gr green"/>....

Notice value="Blue:bl blue" and value="Green:gr green"

Now in your sling model, you can do:

@Model(adaptables=Resource.class)
public class Color{

    @Inject @Named("colors") @Optional
    private String colorValue ;

    private cssClass;
    private label;

    @PostConstruct
    protected void init() {
        // This is a very rudimentary way to illustrate the point
        // you can do this in many other ways/data structures to get the same result
        String[] parts = colorValue.split(":");
        label = parts[0];
        cssClass = parts[1];
    }

    public String getCssClass() {
        return cssClass;
    }

    public String getLabel() {
        return label;
    }
}
