JXTemplate often fail a method call without giving any error
------------------------------------------------------------

                 Key: COCOON-1978
                 URL: https://issues.apache.org/jira/browse/COCOON-1978
             Project: Cocoon
          Issue Type: Bug
          Components: Blocks: Templating
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Simone Gianni


When calling a method on an instance in JXTemplate, if that method does not exist (or JX cannot
find the proper method based on parameters), it fails without any error. IMO it should raise
an error, or at least should raise it in dev mode, because not having a debugger it takes
hours to figure out why it's not working.

As an example, take a JX and try to call a method that does not exist :

<jx:set var="any" value="${obj.getSomethingThatDoesNotExist(cocoon.request)}"/>

Any will simply be null. Moreover, even if "any" is then used :

${any.getSomethingElse()}

Again it will fail without any error, resulting simply in an empty string, making it even
harder.

Being a non compiled language already makes it difficult to make sure calls are correct, having
this "silent fail" behavior makes it even harder, and if you add also the non typized nature
it can make it a nightmare.

Anyway, I don't know if there is a way to fix this in cocoon or if it is a Jexl design problem.
