This should probably be defined in resources.grd rather than above so that it
gets translated properly.

[kcarattini, 2014/09/11 00:08:29]

Does this get exposed to the user? I thought it was an internal error message
(maybe Ben can clarify). This was how it was done in the example Ben sent to me.

That's basically right - these are developer facing, not user facing, and are
not translated.

Good to know, thanks!
