Howard M. Lewis Ship commented on TAP5-1863:
--------------------------------------------
I think it would be nice if we could pass along to the client that the Alert
content was pre-formatted (the equivalent of MarkupWriter.writeRaw()). That
would support the kind of scenarios you describe.
It would be even more effective if the client-side api, the t5/core/alert
module, added some flexibility here.
> Rendering components in Alerts
> ------------------------------
>
> Key: TAP5-1863
> URL: https://issues.apache.org/jira/browse/TAP5-1863
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.3.2
> Reporter: Magnus Kvalheim
>
> We've just upgraded to 5.3.2 and checked out some of the new components.
> The Alerts seems pretty useful, but looks like it's only possible to pass on
> strings.
> I'm thinking a pretty common use-case would be to render some
> components/markup in it - like links.
> I experimented a little by manually rendering a block and pass that on to
> alertManager. Got some inspiration from this thread about rendering blocks -
> http://tapestry.1045711.n5.nabble.com/Howto-render-a-block-and-put-it-into-a-JSON-reply-td5486823.html
> --------
> RenderCommand renderCommand = (RenderCommand)alertBlock;
> MarkupWriter markupWriter = new MarkupWriterImpl();
> RenderQueueImpl renderQueue = new RenderQueueImpl(log);
> renderQueue.push(renderCommand);
> renderQueue.run(markupWriter);
> alertManager.info(markupWriter.toString());
> --------
> That seems to work, but it's a bit clumsy and don't know if it's the
> recommended approach for rendering blocks. Does a convenience method exist
> for rendering blocks/components?
> Not sure if it's possible, but how about if one could pass blocks to alerts
> directly. That could be pretty flexible as well...
> ######REPLY FROM KALLE######
> Certainly the recommended approach is to use the provided render
> queue, rather than create your own - but obviously the current
> implementation doesn't always allow to do so. Completely agree with
> you that rendering links, and, in general, rendering blocks would be
> very useful for alerts. I don't see any major issue why it couldn't be
> supported. Please open an issue for it.
