Hi
I am new to Tapestry, I am using Tapestry 5.2.2 version. I have a
requirement to update another textfield on blur event of a field.
for example:
say I have 2 fields
TextField A
TextField B
Enter any value in TextField A, a server call will be made and update the
Textfield B.
Appreciate a
That sounds interesting.
#1: Is there any 'documentation' to get started with the
MarkupRendererFilter?
I can't see where exactly I can manipulate the DOM in
[renderMarkup(MarkupWriter writer, MarkupRenderer renderer)].

Would it make more sense (performance-wise) to remove the HTML comments in
the 'SaxTemplateParser'?
I remembered that there was an option in Tapestry to compress whitespaces
from templates. I dug around the Tapestry source a bit and found the

Hi..
Could anyone give me an example how to get service bean, without using
@Inject annotation, in page class?
Is it using ObjectLocator? What built-in service to inject, in order to use
ObjectLocator?
I can use this when using tapestry-spring and spring ioc:
@Inject
private ApplicationContext sp
Injecting ObjectLocator into a page or component class is not supported. You
need to provide a wrapper service, which uses ObjectLocator. Then inject it
into your page and retrieve your services.
Alternatively you can retrieve the Registry from ServletContext. Check this
out.

Define "update another textfield". Are you putting some result from the
server in it?
Read up ZoneUpdater:

Although it's annoyingly tricky to refresh form fields. The example
refreshes some plain text.

You could decorate the TemplateParser service and convert its output
to drop the CommentToken objects inside the returned ComponentTemplate
object (that is, return a new ComponentTemplate that filters its
output somewhat).

Hi,
I think I've run into a conceptual understanding roadblock in trying to
setup uploading then displaying of images in my application.
I've got the uploading part working so far, although since my
application is deployed as a WAR, the files upload to a system folder.
That works alright, bu
Hi Howard. Thanks a lot for your explanation.

Cool - thanks for the info!
I just implemented it, works like a charm. In case anyone is interested in
this - here is my code (Scala):
# AppModule
def decorateTemplateParser(parser: TemplateParser) =
new TemplateParser() {
import scala.collection.JavaConversions._
MarkupRendererFilter:
renderMarkup(MarkupWriter writer, MarkupRenderer renderer) {
renderer.renderMarkup(writer);//allow the rest of the filters to
work.
Document doc = writer.getDocument();
//now you can manipulate the dom via the doc variable.
}
You could probably do this, if you felt so inclined.
You can't override SaxTemplateParser directly. Instead, you would override
TemplateParser (contributed by InternalModule), and use that to instantiate
your custom/overridden SaxTemplateParser.
One clarification: template /parsing/ is different
... and I'd tend towards a modified version of what he's already done,
which is to strip out the TemplateTokens as they are parsed by the
TemplateParser. However, what he's done could be improved just a bit.

I think this thread has gotten me very confused.
You have uploaded files, presumably you know where they are and can
identify them. You want to get those files to display in your browser.
In order to do that you create an tag that contains a

Generally I would write a bit of javascript that watches for the blur
event and move the data over.

If you are a Twitter user, you might have noticed that the Tapestry
committers, and others, are using the #tapestry5 tag in their tweets
about Tapestry.
If you use Tapestry and Twitter (even together!) feel free to tweet
about what your are working on, or even just that you like/enjoy
Tapestry.

Thank you very much for your help.
I use the registry from ServletContext.
I'm using this code:
@Inject
private Context context;
and use this statement to get bean:
Registry registry = (Registry)
context.getAttribute(TapestryFilter.REGISTRY_CONTEXT_NAME);
entityManager = registry.getService(clazz
