Any idea why attribute "collectionType" gets ignored?

Hi everyone,

have the following code:

Code: Select all

<p:selectCheckboxMenu id="sysRole" value="#{bean.modelDS.roles}" label="#{labels['general.role']}" multiple="true" filter="false" panelStyle="width:250px">
    <f:attribute name="collectionType" value="java.util.ArrayList" />
    <f:selectItems value="#{bean.allRoles}" />
</p:selectCheckboxMenu>

But mysteriously <f:attribute name="collectionType" value="java.util.ArrayList" /> is ignored and this and other similar components like <p:selectManyCheckbox/> anyway return object of type String[] .

I have another project where attribute "collectionType" worked like a charm, but today got this weird case...

Few notes:
1) value="#{bean.modelDS.roles}" actually binds to model which extends Map, so all getters/setters work via Object get(String) / put(String, Object) methods (not sure whether it is relevant ?!;
2) Payara 4.1.2.172 with manually updated JSF to v2.3.2

Will also try later on other project / JSF version, but currently will be very thankful for any ideas what to check!

Thank you!

PrimeFaces never implemented such a feature - probably it's only supported during inheritance from UISelectMany.
If it doesn't work for you, try to ask the mojarra guys. Could also be a bug in a newer mojarra version

Thank you for quick response! Yep, I have noticed that there is nothing about "collectionType" attribute could be found in PrimeFaces sources, only in JSF source.
Just was wondering - maybe I am missing something this time... As before it was working absolutely fine (in another project)!
