Dutch language with JS Validation doesn't work

With Chronoforms_J1.5_V4_RC1.9 installed the JS Validation Language selection doesn't work correct. When selecting, french, italian, german the validation error's appear correct (in that language). When selecting dutch (nl.js) it reports in english. It does not select the english (en.js) file, but uses it's internal english strings. The selection has a bug, it does not select the dutch (nl.js) file but probably no file at all.

Workaround is choosing an other language and renaming the dutch (nl.js) file so it appears to be the selected language.

Update> Found the bug. The dutch language file (\components\com_chronoforms\js\formcheck\lang\nl.js) contains a corrupt keyword. Edit this file, the first line should be: "formcheckLanguage = {"

Everything works fine after editing this file!

Thanks for sharing!!🙂
