If you go into Admin | Content Types tab and select your page type and the property in question on the pagetype.

The User Interface Panel is where you should be able to update the Display name for the fields/properties ?

I have updated the Display name in the admin panel, however nothing happens on the actual page. See the images below for some details:

Here we can see I have edited the images in the admin interface (Sorry about the swedish language setting)

Here I hover over the property I just changed, but it's name is still "Beskrivning" and it's description is still the old description, even though those should have changed to foo and bar respectively. I have the same issue when changing from code. The values stay the same. I don't want to change the property name in code, although I do believe that would fix it, because then the descriptions the users have already entered will be lost.

Do you have ~/Resources/LanguageFiles ? containing PropertyNames.xml ?

Your properties may be defined in this file... look for an element with same name as your property containing a caption element.

You can try changing this value, or simply removing the language files ?

And I think recycling the site to be sure.

I see the test Alloy site has these language files and has defined metadata properties on the icontentdata type

Thanks for your quick response, that solved my problem! I had an xml file that had the erroneous display names and description.

No problem.

If it solved your problem, would you mind marking the post as the correct answer ?

I would, but nothing happens when I click the "Mark as answer"-button...

Yeah I have had trouble with that button myself :)

The "mark as answer" problem should be fixed now. Please try again :-)
