Tried to run pattern for email cck field which is this module: http://drupal.org/project/email.

I setup my pattern like this:

	<field>
		<type>test</type>
		<name>email</name>
		<label>Email Address</label>
		<group>contact_information</group>
		<option>email</option>
		<widget>text_textfield</widget>
		<multiple>0</multiple>
		<size>40</size>
		<description></description>
		<weight>-2</weight>
		<required>1</required>
	</field>

Pattern fails everytime it gets to this action. What i finally figured out after much effort is that even though the option type for this field is "email", after you save the field, it is saved as type "text" so the pattern never recognizes the "email" type. Just thought id share in case anyone else runs into this problem. My solution is to just not use email module and use simple textfield instead.
