> 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
