column sortBy and locale settings

[petercr4]

We're using built in column sorting on a datatable. We noticed that sort order is wrong for some slavic words which are always in the end of list.

We checked locale settings on the server and clients. It's correctly set to Slovenian (sl_SI). Encoding is UTF8.

Any idea what else could be checked?

you could debug the compare in our WrappedBeanComparator2 class. It should not be a problem of our sorting. Because simple standard String compare performed for String object.

Thanks Ilya for hint. Seems like problem is really with using standard String compare which is not good enough for non English languages. I made some manual sort on collections and instead of using code below

int i=o1.name.toUpperCase().compareTo(this.name.toUpperCase());

which doesn't work well, I used:

// get locale settings for collator
Collator myCollator = Collator.getInstance();
int i = myCollator.compare(o1.name.toUpperCase(), this.name.toUpperCase());

which works as supposed.

So collator should be used for sorting strings. Here is a good article on this subject:
