Is there an equivalent to Abort in EWB? Something that stops the current execution stack, but raises no error dialog or anything?

Related to this, I don't think Exceptions work as documented.

type

EAbortException = Exception;

....

raise EAbortException.Create('');
// this is output as: throw new ("");

....

function TfrmAdminWelcome.ErrorHandler...

// including this stops the output of the loader:
   if (Sender is EAbortException) then
       exit;

Not really a problem - I'll include a magic string in the normal exception, but the manual implies this should work, I think.

Matthew,

It's a JavaScript issue - you can throw Exception descendants, but cannot test for them properly, so EWB just outputs the base Exception instances.  This is mentioned in the manual here:

https://www.elevatesoft.com/manual?action=viewtopic&id=ewb2&topic=Exception_Handling

in the red box:

"While you can create new exception classes that descend from the base Exception class for design-time usage, you cannot do so for run-time usage. Some of the modern web browser implementations of JavaScript do not properly deal with exception class descendants in terms of reporting the proper error message and source line number of the error."

I'll revisit this with EWB 3 and see if the current crop of browsers has improved at all.
