Re: T5 binding problem
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... On 3/6/07, Angelo Luis <[EMAIL PROTECTED]> wrote: No no no...

Re: T5 binding problem
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.

Re: T5 binding problem
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.

Re: T5 binding problem
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.
