Subject Re: A plan for 5.3 / 5.4

i guess your roadmaps (igor, howard) are very promising. 

what i am missing is a decent (official) portlet support in T5. This was 
the main reason some of my customers refused to switch to T5 and chose JSF 
instead (with Liferay). They were all quite impressed by T5 features but 
they didn't want to spend their effort in maintaining a custom portlet 
solution. Those costumers are big companies that already have some kind of 
portlet support and want to reuse their infrastructure. Almost everytime 
we were presenting T5 and its advantages to some managers, someone had to 
ask: does it support portlets (event if they don't use it!). from my 
experience this is a big selling point.

a new JS infrastructure / abstraction layer is overdue as this is the 
reason why there are no (at least not many) fancy JS enabled controls and 
widgets for T5. because everytime you think of creating one, you remember 
that T5 depends on prototype and you dont want to use it anymore. but 
writing T5 components that depend on JQuery, dojo, ... doesn't feel right 
too. i think it would be a big advantage if you could write js library 
agnostic components (with some additional adapters if necessary) and adapt 
to your customers needs.

i'm still not convinced moving from gradle to maven is a good idea. for me 
maven works great and almost any it-company nowadays is familiar with it. 
we are building a custom OSGIfied version of T5.2 using maven. i don't 
know how to achieve the same result with gradle. Also from my point of 
view having a default project layout for all java projects (especially 
open source) is a good (not to say great) idea!

g,
kris

Javassist vs. Plastic vs. ComponentClassTransformWorker

Imagine if you could contribute a "classic"
ComponentClassTransformWorker or some new interface for working with a
Plastic class, both to the same service:
ComponentClassTransformWorker.  The "classic" style would be
transformed, via TypeCoercer, to the new form.  And, of course, we'd
make that work for all service configurations.  That's my plan,
anyway.  Configurations should, instead of complaining that provided
types are bad, attempt to coerce first.

I think the new interface will look more like:

public interface ComponentClassTransformer
{
  void transformClass(PlasticClass componentClass, MutableComponentModel 
model);
}
