MessageBodyWriterSupport implementation not used in collection resource methods

[Ray Conner]

I have extended MessageBodyWriterSupport to provide custom JSON
output. Otherwise, I'm using the scaffolding generated by the jaxrs
plugin.

The custom writer works great for the response to POSTing a new item
(POST to http://..../app/item), and for GET on a specific item (GET
from http://...../app/item/<id>). But it is not being used when I GET
all items (GET from http://...../app/item).

I might very well have something misconfigured.

grails version 2.0.3
jaxrs plugin version 0.6

Additionally, and this is very strange, the presence of the MessageBodyWriterSupport implementation causes GORM to not properly load items from the database. My items have a Map property (mapping strings to strings, as detailed in the grails manual: ch. 5, "Maps of Objects"). The elements of that Map property are not loaded properly by Item.get(id) or Item.findAll(), long before the MessageBodyWriter should even be involved.

I'm getting inconsistent results on this problem with the Map property. It might be something that only happens in IntelliJ. My bad for posting this without more rigorous testing.

Can you please open a ticket and attach a failing test or example app?

Thanks,
Martin

Martin,

Maybe this weekend, life is a bit hectic right now. Corporate IP won't let me attach the app having a problem, but I should be able to create a minimal app exhibiting the behavior.

Turns out the Map problem is a grails/GORM bug.

Kind of funny since a coworker tracked that down and told the story to the rest of us. It's only been a month and had already forgotten.
