[Zope] bug with File Library example on 2.7.0

Running Zope 2.7.0 / python 2.3.3 I ran into a bug with the File Library example app. When you click on the column headers twice to resort in reverse you get an error: Error Type: ValueError Error Value: An integer was expected in the value 'True' The url causing the problem is: .../FileLibrary/index_html?sort=date&reverse:int=True On Zope 2.6.3 / python 2.2.2 the example works and the URL is: .../FileLibrary/index_html?sort=date&reverse:int=1 Tom
