Liferay 7: Custom fields in a new portlet doesn't show up

[7年前 に K F によって更新されました。]

Hi Liferay team,

I created my new portlet and put this fragment in my view jsp

<%
User selUser = themeDisplay.getUser();
%>
<aui:fieldset>
<liferay-expando:custom-attribute-list
className="com.liferay.portal.kernel.model.User"
classPK="<%= (selUser != null) ? selUser.getUserId() : 0 %>"
editable="<%= true %>"
label="<%= true %>"
/>
</aui:fieldset>

I don't get any error but I also don't see defined custom fields. In default My Account portlet from control panel everything works fine. Please help.
