Hi John, Currently there are two types of ESB editors in DevS 3.7.1. 1. Tree structured ESB editor (deprecated) 2. Drag and drop ESB diagram editor (recommended)
Deprecated tree structured ESB editor is outdated and we are not maintaining it.(We are removing this deprecated editor in next DevS 3.8.0 release). You are getting saving issues/design to source switching issues with old editor because it's outdated. So the solution here is to open ESB config files using recommended ESB editor by just double clicking on the config file. (Double click event will trigger config file to open in the recommended ESB diagram editor.) Using other options such as Right click on config file --> "Open With" --> ESB Editor, use "Ctrl" + "Shift" + R to open config files, will result to open config files in deprecated ESB editor. It seems mentioned *java.lang.NullPointerException *exception is not the root cause for the issues. Please attach the full error log($workspace/.metadata/.log) to check the actual error. Thanks, Viraj.
