iView custom property values go away after Save

I have an iView with a predefined list of values to choose from. For example:

portalapp.xml:

<property name="color" value="red">

<property name="type" value="select[red,blue,green]"/>

</property>

When the iView is initially created, I can see the drop-down list with these values. When I select one, then save the iView, the drop-down list disappears (along with all of the predefined values). I can then go back in and put any text in the property and save it, which is obviously undesirable.

Is there a way to prevent this (such that the original list of values is preserved)? This only appears to be a problem with properties I have defined in the XML file. The system properties (that have a list of values) seem to not have this problem.

Thanks,
