IMHO in a DSL a "static cache" has no sense. Perhaps we can define: request-cache="yes|no" for DSL. And this is more explicit. I don't like this attribute is very implementation oriented. People will need to rewrite all the forms in order to take advantage of that. Well, it is very easy using jEdit...but... I think it is not too much dificult (and almost no time consuming) search ancestors looking for a Repeater. Perhaps better is: request-cache="auto|yes|no" When the user don't this attribute in definition.xml it means he want a SSL, right? Wich will be the default behavior using: myWidget.setSelectionList(...); Here we cannot define the cache. I thought we can create a new method: myWidget.setCachedSelectionList(...); The more I think about this, I am more thinking the best is to make this automatically and let cocoon decide when use the cache or not. Another question: How to access the request attributes from DynamicSelectionList.java without touching another file? I cannot see how to get the FormContext from the DSL code. BTW, The code is almost done. Best Regards, Antonio Gallardo.
