Yes, it's a schema.Text

I actually wrote. I needed my own attribute editor to ensure sync of  
the raw vCard field with the other "user friendly" contact fields.  
For this I wrote:

class ContactRawVCardAE(StringAttributeEditor):

     def GetAttributeValue(self, item, attributeName):
         ...

     def SetAttributeValue(self, item, attributeName, valueString):
         ...

and I registered the custom editor with:

def registerAttributeEditors(parcel, oldVersion=None):

     aeDict = {
         'Text+contactRawVCardField': 'ContactRawVCardAE'
     }
     AttributeEditorMapping.register(parcel, aeDict, __name__)

And this works nicely. The custom AE is a subclass of the string  
editor, so I think for many calls the string editor's methods will be  
used.

Note: I had this "squeeze" problem even before creating a custom editor.

Yes, if I have the makeEditor block a root component of the blocks  
three it displays correctly. If I move it inside a makeArea Sublock  
it then gets squeezed.

block three -> makeEditor: works displaying multilines

block three-> makeArea-> makeEditor: the editor gets squeezed to a  
single line with a very little scroll bar.

The note's item content is not enclosed in a block area, thus  
displays correctly...
