The substitution preview in the Translator Row Editor fails if Translator is operated stand-alone. #1095

When Translator is started stand-alone (i.e., via translator.sh or translator.bat, respectively, as far as available, or as java -cp "Structorizer.app/Contents/Java/Structorizer.jar" lu.fisch.structorizer.locales.Translator) then the "Preview" button in the following dialog won't work: grafik Instead, a "silent" NullPointerException stacktrace runs into the error stream:

This is caused by:

  1. a withheld argument value in the getElementName() delegation hierarchy and
  2. missing precautions against null elements in a configuration array.

When started from Structorizer menu, however, this is unlikely to happen.
