T5 binding problem
Hi,
maybe this was reported and solved but here it goes ...
I've tried the tapestry tutorial and it was very nice and easy.
I've made few mistakes but error reporting is great so it was fixed quickly.
the problem occured when I tried to add some of the proposed changes to the
app..
just to test the expressions I added:
<t:comp type="If" test="ognl:index<5">
but I get the error
Failure parsing template context:WEB-INF/Guess.html: The value of attribute
"test" associated with an element type "t:comp" must not contain the '<'
character.
Am I doing it wrong, or it's just a bug to be fixed later....

It may never be; the design of T5 allows for easy property expressions
right in the binding, and more complex expression delegate out to Java
code easily (this is practical in T5 because of the automatic class
reloading).
A lot of the "magic" logic in BeanEditForm and Grid is based on some
APIs that OGNL will have trouble replicating ... in terms of
identifying a property is a type-safe manner, and gaining access to
annotations on the getter and/or setter.

OGNL won't be supported or not yet.

I don't think it's even a matter of choice right now to be honest.
There are still quite a few changes that need to be made before ognl
is suitable for use with T5. (such as the addition of parameter
accessors to handle annotated params, generics, IoC injection ,
removal of static references to make jvm class reloads work , etc....)
The other projects want these kinds of things too (as well as Drew
telling me he specifically wanted to see the IoC stuff happen ), so
there's more than enough pressure to get it done.
Howard and I both know it's not ready ~yet~, but if/when it does get
to that point I'll ping him and let him know...

No no no...
How can have a null handler now???
If a have a customer -> address -> street in a text component, for example "
custumer.address.street" and i dont instanciate a address, a
NullPointerException is throw. With a ognl null handler, if the address is
null he creates one , like Webwork... i dont need to instanciate all object
graph to use in a page...
i will have this same problem in t5?

Yep, that's the intention.
Not using OGNL falls into the "blazing speed - no reflection" goal.
Jesse's busy taking the reflection out of OGNL, so it may make a
comeback as an add-on.

thnx,
I did add a syntethic property to do the task,
but thought ognl was supposed to work ....
actualy I like the approach via property more, since then I have
autocomplete and all the stuff I'm used to while writing java code,
and auto reloading of classes makes it as fast to test, as if it was written
in the template :)

Two problems here:
1) Not well formed XML. That "<" inside the test attribute isn't
allow. Use <
2) OGNL isn't supported in T5.
For anything more complicated than a property access, you do the work
in Java code as a synthetic property.
