Re: [udig-devel] postRendering problem (bug??)

But you are correct it does look like a bug.

I'm getting a message (it's intermittent) in the status bar saying:

"Timed out while rendering this layer. Seems to have blocked, check that the
server is up"

I don't think it's a valid message, given my layer is rendering just fine. I'm calling refresh from another thread (it's doing it safely) and the layer is getting refreshed. I tracked down the message, and it seems that the implementation of RenderExecutorComposite#CompositeRenderJob#postRendering() is a little strange. If the IRenderer is not in the DONE state, then we get the timeout message. Moving up the stack, I can't see how the IRenderer
lifecycle is appropriately managed.

Given this code: (RenderJob#run(IProgressMonitor))

getExecutor().getRenderer().setState(IRenderer.RENDERING);

try {

startRendering(bounds, monitor);

} catch (Throwable renderError) {


handleException(renderError);

getExecutor().getRenderer().setState(IRenderer.DONE);

return Status.OK_STATUS;

}


postRendering();

return Status.OK_STATUS;


The IRenderer may not get set to IRenderer.DONE.
