I am trying to learn and develop with Bonita BPM. Last week i discovered a bug in UI designer. I can install Bonita Studio, create flow-charts etc. but when i open UI Designer, it doesn't contain any widgets, only tabs container and form container. When i tried to create custom widget i get this error.
My OS was Turkish and in Turkish language capital i letter is "I" but in english it is "I". I noticed this part of error, "org.bonitasoft.web.designer.model.widget.PropertyType.CHOİCE". There is a char in this code that doesn't supported by software. So i changed my language to EN then UI Designer started to show all widget and i was able to create my custom widgets. But this is a bug, it could cause other problems.
Windows 10, Ubuntu 16.04
