Description

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
