try{

roleDefinitionCollection = spWeb.AllRolesForCurrentUser;

}

catch(Exception ex) {

if (!ex.Message.EndsWith("0x80040E14")) // Not the specific case we're looking for, rethrow

throw;
...

In other words, I took out the bit that was looking for a certain type of exception and replaced it with a normal System.Exception and changed the test to just check the end of the exception message.

Anyway, this trapped the error and my test app called this routine thus:-

foreach

(SPWeb myWeb in checkedWebs)  {

if (!myWeb.EffectivePresenceEnabled) {MessageBox.Show("Effective presence NOT implemented on this site"); }

if (IsInRole(myWeb, "SLK Instructor")) { 

MessageBox.Show("Yes, you seem to be an instructor");

}

else {

MessageBox.Show("No, you do not appear to be an instructotr");

}

}

And that returned the message "Yes, you seem to be an instructor".

So - that works, but I still get the error when I try to allocate training material to users (with the error message in my last post above). So - could the error be elsewhere now? Any ideas?

I'll give it a go Jay :)

OK - patch uploaded (id #1803). CPC complained about unversioned items when I created the patch - let me know if that means there's something else I should be doing.
