Hi, Assuming you are complaining about not being able to logical insert a object from Java code, let me try to explain. The problem is that your understanding of logicalInsert is not quite correct. You can only call logicalInsert from within a rule consequence. The inserted object will remain in working memory for as long as the "inserting rule" holds true. Therefore, it does not make sense to call logicalInsert from your Java program.
