GenericConversionService ignores converters for arrays [SPR-7462]

[spring-projects-issues]

Dave Syer opened SPR-7462 and commented

GenericConversionService ignores converters for arrays: if you add a converter for an array type it is ignored at runtime. The conversion service instead tries to be clever and looks for a converter for the element type in the array. It might find one, but even if it does, it would be the wrong default choice of converter because there is an exact match between the target type and an existing converter.

Dave, what exactly failed for you there? I added unit tests for a Converter<String[], Integer[]> and a Converter<String, Integer[]> - and both work for me... against the latest Spring 3.0.4 snapshot at least.

I tried Resource[] and a custom Service[] interface. Try something non-primitive?

I tried a custom Converter<String[], Resource[]> - works for me as well. I'm afraid you'll have to provide a failing test case against the latest 3.0.4 snapshot...

Dave, any luck in reproducing this in a unit test against the latest 3.0.4 snapshot?

This was a problem in an older 3.x (up to 3.0.1). Seems OK with 3.0.4 (and I thin with 3.0.2).
