It seems that the latest version of the IntelliJ plugin (installed today) has an issue with the xml designer. It fails to show the screen.
Sorry, failed to mention I am using Windows 10, IntelliJ 2019.2.3 and latest CUBA plugin 11.3-183. Worked previously. Set up a simple project with customer entity (name & address) and edit/browse screen. Under screens select the customer-edit xml. The text works fine the designer screen fails with an ide error message (see below):
Exception in CUBA plugin (11.3.183)
ide_error.txt (2.1 KB)
Also using Java 11.0.4
Thanks for the information, here is an issue: https://youtrack.cuba-platform.com/issue/STUDIO-6872.
As a workaround, you can try to switch to Java 8: https://intellij-support.jetbrains.com/hc/en-us/articles/206544879-Selecting-the-JDK-version-the-IDE-will-run-under.
After that please check “Use JxBrowser embedded browser” option in plugin settings.
Thank you. Appreciated.
