Hi,
Hi!
I'm using Tapestry 5.3.
If you want to render a block or component or anything that can be coerced
to a RenderCommand, Tapestry 5.4 has the PartialTemplateRenderer service:
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/PartialTemplateRenderer.html.
Example:
https://github.com/apache/tapestry-5/blob/master/tapestry-core/src/test/java/org/apache/tapestry5/integration/app1/pages/PartialTemplateRendererDemo.java
You can see and copy its sources from
https://github.com/apache/tapestry-5/blob/master/tapestry-core/src/main/java/org/apache/tapestry5/internal/services/PartialTemplateRendererImpl.java.
In a Tapestry component, I'm trying to implement an event handler that
creates responses to AJAX requests.
I know that I can call MarkupWriterFactory#newPartialMarkupWriter to get
an instance of MarkupWriter and then generate the response using this
MarkupWriter instance. The built-in mixin Autocomplete generates
responses to AJAX requests in this way.
You really don't need to do it this way.
However, I wonder if there is a chance to create such response using a
Tapestry block rather than generating the response "manually" via
MarkupWriter.
Just return the block instance in your AJAX event handler method.
If I just return an instance of block from the event handler, an
exception is thrown.
Weird. Tapestry does support block event handler return methods for AJAX
requests (i.e. the ones in which Request.isXHR() returns true). How are
you testing your event handler method?
