Dan Haywood commented on ISIS-766:
----------------------------------
Sorry, I guess I didn't explain myself well enough about ExceptionRecogniser
service. If you are getting some new sort of exception then we *want* that
exception to be recognized, so that it can be rendered like a validation error
in the prompt.
So, rather than remove the service, what I'd like you to do is see if you can
figure out what that exception you are seeing is. Then we could extend the
ExceptionRecogniser service to recognise this new exception type and thus not
cause the problem. Hence, try adding a breakpoint in your IDE on *any*
exception thrown.
Meanwhile, I am using the big xlsx file (1.6Mb), have uploaded it 4 times in
succession, no errors.

> Isis service or ViewModel method getting called twice.
> For ex:
> I have one Hidden service which has lookup method with @HomePage returning a
> ViewModel instance using newViewModelInstance(..) method and that renders one
> action method taking Blob parameter as button. It's basically upload button
> to upload a file. When I click on upload button, this upload method called
> and completed the uploading and again getting called second time by itself.
> And this is inconsistent behavior. Some times its working(meaning called only
> once) but some other times it's not.
> So I tried this upload action with service class by extending AbstractService
> which appears in the menu with Upload action. Here also it's the same issue.
> Please find attached files in this Jira as I don't have GIT client to push
> the files in github
