Hey guys, If I try and display an alarm status table on a pop up window that is docked without a header on it I get the following error: [code]com.inductiveautomation.ignition.common.xmlserialization.SerializationException: Error invoking [AlarmStatusTable]com.inductiveautomation.factorypmi.application.components.AlarmStatusTable[Alarm
