The defect only happens (on my machine) if the target folder is outside of any project; or possibly within an unrecognized / broken project folder. For testing, I recommend to close all project so that the Wizard will allow to enter the target location folder manually. Reporter - please give a more specific scenario for reproduction. I've fixed the NPE in the case project is null, but that does not fix the workflow in the Wizard: it assumes that the user works with projects and tries to display schemas available in the project (or globally). Fixed in jet-main#71323628f199
Integrated into 'main-silver', will be available in build *201407170001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/71323628f199 User: Svata Dedic <sdedic@netbeans.org> Log: #242796: avoided NPE when creating XML which does not belong to any project
