ISIS-1461: alternative fix for concurrency exception when click on link.
The solution is more localized; just disable concurrency checking when
rendering a link.
> More reliable fix to concurrency exception
> ------------------------------------------
>
> Key: ISIS-1461
> URL: https://issues.apache.org/jira/browse/ISIS-1461
> Project: Isis
> Issue Type: Bug
> Components: Core: Viewer: Wicket
> Affects Versions: 1.12.2
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: 1.13.0
>
>
> The concurrency exception addressed in 1.12.x has reappeared.
> To reproduce:
> - https://github.com/danhaywood/ddd-london-20160601
> - dev_summer branch
> - create Presenter
> - click 'Create' (the contributed action to propose a session)
> - in the resultant Session, click on the "Other" tab (where the Presenter
> reference lives)
> - bam, concurrency exception.
> Suggest the fix instead is to postpone the EntityPage#buildGui into the
> onRender, so that reload all objects on the redirect. Have considered this
> in the past but had been able to make it work without resorting to this.
