What can be the cause for an unset clientid?

Hello,

I'm currently debugging regarding a Logmessage "ERROR [ExceptionHandlerBridgeImpl:81] null" in a JSF portlet.

The cause may be that the clientId is unset for a primefaces column.

The functionality I've implemented is default filtering for a primefaces datatable.

According to my debugging primefaces sees the columns (column id's are correct), but "clientid" is unset in the colums.

I'm asking here because I'm unsure where to look for further details.

The component hierachy is view -> form -> composite -> primefaces panel -> primefaces datatable -> column...

My versions are DXP 7.1 (FP dxp-19-7110, hotfix hotfix-4981-7110) with portlet dependencies

com.liferay.faces.alloy-3.0.3.jar com.liferay.faces.bridge.api-4.1.0.jar com.liferay.faces.bridge.ext-5.0.5.jar com.liferay.faces.bridge.impl-4.1.4.jar com.liferay.faces.portal-3.0.5.jar com.liferay.faces.util-3.3.0.jar com.liferay.
portal.configuration.metatype.api-1.2.1.jar com.liferay.portal.configuration.metatype.definitions.annotations-3.0.10.jar com.liferay.portal.configuration.metatype.definitions.equinox-3.0.4.jar javax.faces-2.2.20.jar javax.faces-api-
2.2.jar javax.inject-1.jar primefaces-7.0.14.jar

Best regards,
Gunnar

edit: corrected "default filtering" instead of "default sorting"

Further investigations:

still no clientIds when I'm working without the composite (hierarchiy view -> form -> primefaces datatable -> column...)
here an NPE is thrown instead of "ERROR [ExceptionHandlerBridgeImpl:81] null" (see below)
the NPE is only thrown when I use "filterBy" for the datatable itself to apply default filtering
because this leads to primefaces trying to identify the column from the given FilterState by it's clientId which is unset
when I'm binding the dataTable and log the column clientIds in some Getter I can see column clientIds are correctly set before the NPE occurs
so the first problem are unset clientIds via executeRender / renderView / encodeChildren / encodeEnd
and the second problem is Primefaces 7 not testing for a null clientId
still unsure whether the first problem is a bug in Liferay Faces or Primefaces or normal behaviour

I've applied a "client side workaround", but maybe this topic is still an unsolved problem and no normal behaviour.

My "client side workaround" is (instead of "filterBy" for "datatable")

...
    </p:dataTable>
</p:panel>
<h:outputText value="#{miController.defaultFilterWorkaround}"/>

along with

public String getDefaultFilterWorkaround()
{
    PrimeFaces.current().executeScript("PF('" + CONTRACTS_TABLE_WIDGET_VAR + "').filter()");
    return "";
}
