java.lang.NullPointerException

Mirth Project | Nick Rupley | 2 years ago
  1. 0

    The Channel Writer is actually returning null when the channelList variable is null. This was "needed" before because the channel ID was grabbed from that list. However with MIRTH-2961, the ID comes directly from the text field, so there's no need to use channelList anymore. This is noticeable now with the resource ID changes. When you load a channel for the first time, and the first destination isn't a Channel Writer, but then you switch to a Channel Writer, you'll get the following exception: {code}Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mirth.connect.client.ui.ChannelSetup.saveDestinationPanel(ChannelSetup.java:1133) at com.mirth.connect.client.ui.panels.connectors.DestinationSettingsPanel.updateQueueMessages(DestinationSettingsPanel.java:135) at com.mirth.connect.client.ui.panels.connectors.DestinationSettingsPanel.setProperties(DestinationSettingsPanel.java:83) at com.mirth.connect.client.ui.panels.connectors.ConnectorPanel.setProperties(ConnectorPanel.java:164) at com.mirth.connect.client.ui.ChannelSetup.generateMultipleDestinationPage(ChannelSetup.java:3124) at com.mirth.connect.client.ui.ChannelSetup.destinationSourceDropdownActionPerformed(ChannelSetup.java:2840) at com.mirth.connect.client.ui.ChannelSetup.access$38(ChannelSetup.java:2818) at com.mirth.connect.client.ui.ChannelSetup$31.actionPerformed(ChannelSetup.java:2497) at javax.swing.JComboBox.fireActionEvent(JComboBox.java:1260) at javax.swing.JComboBox.setSelectedItem(JComboBox.java:588) at javax.swing.JComboBox.setSelectedIndex(JComboBox.java:624) at javax.swing.plaf.basic.BasicComboPopup$Handler.mouseReleased(BasicComboPopup.java:835) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:290) at java.awt.Component.processMouseEvent(Component.java:6516) at javax.swing.JComponent.processMouseEvent(JComponent.java:3320) at javax.swing.plaf.basic.BasicComboPopup$1.processMouseEvent(BasicComboPopup.java:499) at java.awt.Component.processEvent(Component.java:6281) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4872) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4698) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4492) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at java.awt.Container.dispatchEventImpl(Container.java:2273) at java.awt.Window.dispatchEventImpl(Window.java:2719) at java.awt.Component.dispatchEvent(Component.java:4698) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:735) at java.awt.EventQueue.access$200(EventQueue.java:103) at java.awt.EventQueue$3.run(EventQueue.java:694) at java.awt.EventQueue$3.run(EventQueue.java:692) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:87) at java.awt.EventQueue$4.run(EventQueue.java:708) at java.awt.EventQueue$4.run(EventQueue.java:706) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:705) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91){code} Doing a check in saveDestinationPanel would fix it, but we should also get rid of the null check in ChannelWriter since it's no longer necessary.
