mapping UI. It seems like there is a bug that you have found: file it over the normal issue process <a href="http://www.axonivy.com/ch-en/bpm-services-bpmn-20/bpm-support-bpm-service/">http://www.axonivy.com/ch-en/bpm-services-bpmn-20/bpm-support-bpm-service/</a> A demo project is required.</p> <p>To work around the problem. Try to use another context data class. Just close all opened process editor instances try to create the new Html Dialog with another DataClass of your choice. If that doesn't work, open explicitly a very simple DataClass and open the new wizard afterwards.</p>Reguel WermelingerWed, 15 Jun 2016 15:20:00 -0400https://answers.axonivy.com/questions/1800/ai-designer-unable-to-open-or-create-a-dialog-form/1812
