Ranganath Chittari updated ISIS-766:
------------------------------------

    Attachment: Upload-Invocation-Failed.log
                dom.zip

Hi Dan,
PFA dom.zip file which contains source code.
I updated isis-wicket-viewer to 1.5.0. In this version method is not being 
called twice, its called only once but after that invocation failed exception 
occured, PFA log for the same.

the method is defined in 
co.wipro.wess.welcome.ODSProvisioning.upload(@Named("Browse sheet")Blob 
provSheet)

BTW, I am trying to install Egit in my eclipse to publish the src code. Can you 
please give me the url where should i publish it. It will be used for me to 
publish example projects there for future support also

> 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
