Can't hide fields on view screen using behaviours

[Richard Burstiner]

I have behaviors set up to hide fields based on a user's custom field group membership (Group Responsible). The behavior works perfect on create and edit screens but is ignored on the view screen. Any ideas where I went wrong? Thank you.

My behavior setup is:

Here is the XML:

<config name="ITS: Hide Notes" use-validator-plugin="false" guideWorkflow="null">
<field id="customfield_11010" validator-script="" validator-class="" validator-method="" readonly="false" required="false" hidden="true" validator="server">
<except custom-field-group="customfield_11005"/>
</field>
</config>
