Cannot retrieve custom user variables

[Riley Pickerl，修改在11 年前。]

Hello,
I am having a problem retrieving a custom variable I have set for users. I have set a custom user variable with key "addressBookNumber", and assigned the approriate values to the users.
In my code I have:

		try {
			User currentUser = PortalUtil.getUser(request);
			String addressBookNumber = currentUser.getExpandoBridge().getAttribute("addressBookNumber").toString();

		} catch ...

This works and returns the result for when the admin user is logged in. However with a different user (one with less permissions) this code throws an exception:
javax.portlet.PortletException: java.lang.NullPointerException

Is there some restriction on who can grab the values, how do I get around this?

Thanks,

Could be many reasons for the NPE... Perhaps it did not return the currentUser, perhaps there's no result from getExpandoBridge(), or no result from getAttribute().

What it boils down to is that the user does not have permissions on the expando item. You'll have to grant privileges on the custom field so others can access them.

It was the permissions, thanks!
