> Link components should not render during rewind in portlet mode
> ---------------------------------------------------------------
>
> Key: TAPESTRY-525
> URL: http://issues.apache.org/jira/browse/TAPESTRY-525
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Environment: Tapestry 4.0 beta 3, Jetspeed 2.0-M3
> Reporter: Raphael Jean
> Assignee: Jesse Kuhnert
> Fix For: 4.0.1
> Attachments: TAPESTRY-525-patch.txt
>
> When running as a portlet, there is no way to generate a link during the
> processAction() phase, that is the rewind phase.
> When a Link component attempts to render its link during rewind, the
> PortletLinkFactoryImpl crashes because _renderResponse is null.
> One solution is to change the renderComponent() method of
> AbstractLinkComponent:
> protected void renderComponent(IMarkupWriter writer, IRequestCycle cycle)
> {
> + if (cycle.isRewinding())
> + return;
> getRenderer().renderLink(writer, cycle, this);
> }
> Not quite sure about the side effects...
