Unable to get clientId in a component [T5.3.8]

[Tony Nelson]

I’m trying to build a simple component that references up to 4 components on my 
page.

I’m using the component like this:


                <t:dateRangePreset
                        t:dateRangeFrom="dateRangeFrom" 
t:dateRangeTo="dateRangeTo"
                        t:relatedRangeTense="FUTURE"
                        t:relatedRangeFrom="compareDateRangeFrom" 
t:relatedRangeTo="compareDateRangeTo"
                        t:disableDateRangePeriodTypes="DAILY" 
t:disableDateRangeTense="FUTURE" />


dateRangeFrom, dateRangeTo are both required in the component, and work fine

    @Parameter(required = true, defaultPrefix = BindingConstants.COMPONENT)
    private Field dateRangeFrom;

    @Parameter(required = true, defaultPrefix = BindingConstants.COMPONENT)
    private Field dateRangeTo;

relatedRangeFrom and relatedRangeTo are non-null, in after render, and they are 
the right type, but the clientId always returns null

    @Parameter(required = false, defaultPrefix = BindingConstants.COMPONENT)
    private Field relatedRangeFrom;

    @Parameter(required = false, defaultPrefix = BindingConstants.COMPONENT)
    private Field relatedRangeTo;


afterRender() does the normal things

    @Import(library = "DateRangePreset.js")
    void afterRender() {

        JSONObject specs = new JSONObject();
        specs.put("select", "#" + dateRangePresetSelect.getClientId());
        specs.put("dateRangeFrom", "#" + dateRangeFrom.getClientId());
        logger.info("ff: " + relatedRangeFrom);

        if (relatedRangeFrom != null) {
            logger.info("rel: " + relatedRangeFrom.getClientId());
            // specs.put("relatedRangeFrom", "#" + 
relatedRangeFrom.getClientId());
            specs.put("relatedRangeFrom", "#compareDateRangeFrom");
        }

}

In the log I see

[INFO ][DateRangePreset] ff: 
org.apache.tapestry5.corelib.components.DateField@46490fee
[INFO ][DateRangePreset] rel: null


The only thing that’s different between the required DateFields and the 
optional ones, are that the required ones are before my component, the optional 
ones are after my component, but that shouldn’t have anything to do with.

For completeness, here is more of my .tml file, what you see here are the two 
required date fields, my new component, and then the two optional date fields.

Thanks in advance for any help.
Tony
