+Broken applications
+===================
+
+When some broken application raises DuplicationErrors during creation,
+these problem will not be hidden away.
+
+We first setup the environment:
+
+  >>> from zope.app.wsgi.testlayer import Browser
+  >>> browser = Browser()
+  >>> #print dir(browser)
+  >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw')
+
+We have an application type available, which raises DuplicationError
+during creation intentionally:
+
+  >>> browser.open('http://localhost/++grokui++/applications')
+  >>> 'IntentionallyBrokenApp' in browser.contents
+  True
+
+If we try to add an application of that type, the traceback will be
+visible:
+
+  >>> browser.handleErrors = False
+  >>> subform = browser.getForm(
+  ...             name='grokui.admin.tests.brokenapps.IntentionallyBrokenApp')
+  >>> subform.getControl(name='name').value = 'mybrokenapp'
+  >>> subform.getControl('Create').click()
+  Traceback (most recent call last):
+  ...
+  DuplicationError: Intentional DuplicationError
+
+If, however, we try to add two working apps under same name, the UI
+will inform us of the problem (without a traceback):
+
+  >>> browser.open('http://localhost/++grokui++/applications')
+  >>> subform = browser.getForm(
+  ...             name='grokui.admin.tests.brokenapps.WorkingApp')
+  >>> subform.getControl(name='name').value = 'somename'
+  >>> subform.getControl('Create').click()
+
+  >>> subform = browser.getForm(
+  ...             name='grokui.admin.tests.brokenapps.WorkingApp')
+  >>> subform.getControl(name='name').value = 'somename'
+  >>> subform.getControl('Create').click()
+
+  >>> print browser.contents
+  <html xmlns="http://www.w3.org/1999/xhtml">
+  ...
+  ...Name `somename` already in use. Please choose another name...
+  ...
