I created a optimization for my model. the model runed and took a long time. However, I got the following error message. Does it actually indicate that OptQuest can not be invoked? java.lang.RuntimeException: Optimization is not in progress. at com.xj.anylogic.engine.ExperimentOptimization.a(Unknown Source) at com.xj.anylogic.engine.ExperimentOptimization.getCurrentReplication(Unknown Source) at goodwill.Optimization._text10_SetDynamicParams(Optimization.java:494) at goodwill.Optimization.access$9(Optimization.java:486) at goodwill.Optimization$10.draw(Optimization.java:1515) at com.xj.anylogic.engine.presentation.ShapeGroup.draw(Unknown Source) at com.xj.anylogic.engine.Presentable.drawPresentation(Unknown Source) at com.xj.anylogic.engine.presentation.Panel.e(Unknown Source) at com.xj.anylogic.engine.presentation.Panel$c.run(Unknown Source)
