I am building a version 5.1 (.bpmn file extension) rules-flow diagram using the Eclipse plugin. I am writing rules based constraints (as opposed to code constraints), and I would like to call a static Java method from some of my constraints. If I was working in a .drl file, and I wanted to call a static method in my LHS, I could use one of the following, in the import section of the file: import static my.package.MyClass.SomeStaticFunction or import function my.package.MyClass.SomeStaticFunction If I open a constraint, and open the "Imports editor", I can add imports for classes. If I add the first import above to this dialog, and save the .bpmn file, when I open the Imports editor again, I have the following: import static and no reference to the function. If I add the second import above in the same place, when I save and reopen the dialog, the import function line is completely gone. I can't see any reference to the function in the .bpmn file opened in a text editor, either. Is this the expected behavior? If so, how can I call a static Java method from my constraint? Do I have to reference the full package path of the method? Can I only do this from a Java code constraint? The documentation is silent on the topic of importing a function for rules constraint, although it says the format is the same as the LHS of a rule in a .drl file. I'm using Drools version 5.3.0.Final. -- View this message in context: http://drools.46999.n3.nabble.com/Import-static-or-function-in-rules-flow...
