hmm...This is an event handler for ajax action. I access it via
ajax('/somepage:event') at client side. I don't see any problem for
Tapestry to handle the json return value. And it works if I skip the
getMarkup for the block. The client receives the json string without
problem.

You can use a richer language like LESS or SASS to write e. g.:
.a {
color: red;
.b {
font-weight: bold;
}
.c {
height: 1px;
}
}
instead of
.a {
c: r;
}
.a .b {
f-w: b;
}
.a .c {
h: 1px;
}

Check the "TriggerFragment" mixin source code. You can make a similar mixin
to do the same that it does but for multiple components. I'm not sure how
to accept an array of components as a parameter mixin though.
There still may be an easier way but I thought this might help a bit. I'd
like to know
It's in the docs:

Can I somehow trigger to formfragments with one component?
My goal is to swap two fragments on a checkbox click, where one is initially
shown, and on checkbox click it is hidden an another one is shown. But as I
cannot assign the same t:id to two fragments, how can I trigger two
fragment-id's at
Thank you. I simply remembered it wrong.
For the curious: this works as expected:

this.article = articleService.getPublicArticle(articleID);

return articleUnknown;
Hmm I'm still stuck with a NPE @ List children = tbody.getChildren();
Which means tbody is null. But why?

In an Ajax request, returning a JSONObject is completely appropriate return
value from a component event that expects a page navigation result. This
will mix-and-match well with AjaxResponseRenderer (under 5.3 and 5.4); that

Tapestry does NOT accept JSONObject as a return value from a component event.
If you want to make a JSONObject available in your javascript, you should
use AjaxResponseRenderer.

Hi,
how can I negate a triggerfragment? So that it only shows up if checkbox is
/un/checked?
Especially: why does the following not work?
It initially does not show the fragment (as default value of object.bool =
true). But if I uncheck the checkbox, it does not trigger the fragment. BUT

I've been working on a demo gallery component. The gallery uses a table to

No. In this case, as null doesn't seem to be valid value for your

I figured is might be more coercable type to use. But if its thought to be

Hi Lance,
I also tried this. But there is some problem. I had to handle the json
in this getMarkup method. Otherwise the json returned in my event
handler is not rendered.
Object onEventXXX()
{
JSONObject result=new JSONObject();
result.put("html",getMarkup(myblock) );
return result;
}
Thanks. I tried this and it works. One limitation is that, all the
content in the block must be enclosed in a single html element. If the
block is like this:
...
The result only renders one tr element. I have to enclose the loop in a
div to get all the rows rendered. Don't know why though.

This mixin purpose is to trigger a "prepare" event before rendering a
component. It has nothing to do with checking or unchecking a checkbox.

OK you're right, the method is triggered without the annotation. BUT: it is

You add the @MixinAfter annotation that defers the render state behavior of
the mixin after the behavior of the component. I did not add this to my
exemple.
Anyway, I'm not sure but I think that there is already a prepare event for
each fields (like the checkbox) of a form.

As for your problem with debugging. Tapestry transforms your component
classes such that they no longer read/write to member variables in your
class. Instead, getters and setters are generated that are backed by a
thread local.
