Aha! Finally got to the bottom of this one by creating a little
test suite for myself. Turns out that, besides ConvertUtils being
awesome, there is a dichotomy.
The conversion from String[] => int[] works as expected.
The conversion from int[] => String[] is some quirky shit.
Basically, int[] => String[] looks for some format like {1,2,3} as a
string and makes that into a String[] array, so it takes a String
and makes a string array. To me, this is not really the right
converter at all. Here is the issue, my model returns an int[]
array of industryIds. My form has a select box which is
LabelValueBean collection which takes an array of String[]. So when
copyProperties takes my model bean to populate the form bean, it
turns a nice int array like
int[] industryIds = {2,8,9,2};
into
String[] industryIds = {null,I,null,fd54d6}
As you can see, this will certainly not populate the form correctly.
So now I am digging into adding my own converter. I will get back
to you when it is done.
