I’m running Jasper Studio 6.1.0 and trying to create a style template for a series of reports my colleagues and I have to write - (File/New/Style Template File). The popup shows. I enter the name. The new template appears in the editor with one entry called “SimpleStyle” SimpleStyle contains no attributes. When I select it (click on it), then in the “Properties” panel select “Style” Jasper Reports throws an error: An error has occurred. See log file for more details. java.lang.NullPointerException A look into the error log shows : eclipse.buildId=unknown java.version=1.7.0_80 java.vendor=Oracle Corporation BootLoader constants:

org.eclipse.equinox.launcher.Main.run(Main.java:1438) Is there a known solution to this issue? Ultimately I’d like to create a series of styles that inherit attributes from each other, so that we can speed up development.
