Warehouse Management

Здравствуйте! Я установила Warehouse Management на ADempiere 3.5.4. Но при создании Inbount/Outbound Rule появляется ошибка,сама система ничего не говорит,а вот Eclipse выдает следующее:
-----------> GridTable.saveWarning: Error - [11] -----------> MTable.getClass: No class for table with it entity: WMRule [11] -----------> MRule.save: Set Org to 0 [11] -----------> MRule.save: beforeSave - MRule[0-null] [11] java.lang.NullPointerException at org.compiere.model.MRule.beforeSave(MRule.java:204) at org.compiere.model.PO.save(PO.java:1986) at org.compiere.model.GridTable.dataSavePO(GridTable.java:1831) at org.compiere.model.GridTable.dataSave(GridTable.java:1190) at org.compiere.model.GridTab.dataSave(GridTab.java:903) at org.compiere.apps.APanel.cmdsave(APanel.java:1915) at org.compiere.apps.APanel.actionPerformed(APanel.java:1604) at org.compiere.apps.AppsAction.actionPerformed(AppsAction.java:286) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source)
