Created attachment 334 [details] The error when the "Save Test Cases" button is clicked I encounter a problem when I try to generate test cases with Yggdrasil on the last Uppaal version. Indeed, this message appears when I click on the "Save Test Cases" button, there is an "Caught unexpected java.lang.NullPointerException". At first, I was thinking that the problem comes with my modelling. But there is the same problem with every others models, including the tutorials. If I use the same model under the 4.1.19 version, the test generation works fine.
fix released in 4.1.23
