Re: [dali-dev] JPQL query plans?

[Neil Hauge <neil.hauge@xxxxxxxxxx>]

Hi Tom,

I updated the bug to respond to most of your questions.  Adding 
validation and code completion for JPQL queries would indeed be great 
features, but do present some challenges.  It is possible that 
validation could be accomplished by hooking into a given runtime to 
provide at least basic query validation.  There are some possibilities 
here with leveraging EclipseLink for this functionality, or plugging 
into a given runtime through some extension mechanism. 

Code completion is the most challenging, given that a custom JPQL parser 
may need to be built for this purpose, which is a huge effort.

So, we are open to the idea of supporting these features, and are 
welcoming any contributions in this area. : )  Currently this support 
isn't planned for our 2.0 release.  You may want to enter some bugs for 
these in bugzilla.
