Hi,   I am using microflow as DataSource to set Boolean attributes to TRUE/FALSE if the logged in user belongs to Particular role. But the microflow is getting called twice where in I’m receiving the below error. Additionally, one observation from my end is that – For the second time, The Object is empty and so the change object for boolean values is giving error But I don’t understand why it’s calling the flow twice. There is no refresh happening while commit of the object. Error –  com.mendix.webui.WebUIException: Exception while retrieving data for 'MyFirstModule.ReviewerUI.dataView2' on document 'MyFirstModule.ReviewerUI'     at com.mendix.webui.actions.client.RetrieveAction.$anonfun$apply$3(RetrieveAction.scala:99) Caused by: com.mendix.modules.microflowengine.MicroflowException: Change object 'Some(ExtendedOrders)' should not be null     at MyFirstModule.ReviewerUI_PendingCases (Change : 'Change 'ExtendedOrders' (ShowRBAMButton, ShowWWBAMButton)') Advanced stacktrace:     at com.mendix.modules.microflowengine.MicroflowUtil.processException(MicroflowUtil.java:83) Caused by: java.lang.IllegalArgumentException: Change object 'Some(ExtendedOrders)' should not be null     at com.mendix.modules.microflowengine.actions.mxobject.ChangeAction.execute(ChangeAction.scala:43)     at com.mendix.modules.microflowengine.actions.mxobject.ChangeAction.execute(ChangeAction.scala:12)     at com.mendix.modules.microflowengine.microflow.impl.MicroflowObject.$anonfun$execute$1(MicroflowObject.scala:32)     at scala.Option.flatMap(Option.scala:283)     at com.mendix.modules.microflowengine.microflow.impl.MicroflowObject.execute(MicroflowObject.scala:29)     at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.$anonfun$executeAfterBreakingIfNecessary$2(MicroflowImpl.scala:167)     at scala.Option.flatMap(Option.scala:283)     at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAfterBreakingIfNecessary(MicroflowImpl.scala:167)     at com.mendix.modules.microflowengine.microflow.impl.MicroflowImpl.executeAction(MicroflowImpl.scala:114)     at com.mendix.systemwideinterfaces.core.UserAction.execute(UserAction.java:46)     at com.mendix.basis.actionmanagement.CoreActionHandlerImpl.doCall(CoreActionHandlerImpl.scala:71)     at com.mendix.basis.actionmanagement.CoreActionHandlerImpl.call(CoreActionHandlerImpl.scala:48)     at com.mendix.core.actionmanagement.internal.InternalCoreAction.call(InternalCoreAction.scala:25)     at com.mendix.basis.actionmanagement.ActionManager.$anonfun$executeSync$2(ActionManager.scala:80)     at com.mendix.util.classloading.Runner.withContextClassLoader(Runner.java:19)     at com.mendix.basis.actionmanagement.ActionManager.executeSync(ActionManager.scala:79)     at com.mendix.basis.actionmanagement.MicroflowCallBuilderImpl.execute(MicroflowCallBuilderImpl.scala:38)     at com.mendix.webui.actions.client.RetrieveAction.retrieveAllByMicroflow(RetrieveAction.scala:120)     at com.mendix.webui.actions.client.RetrieveAction.$anonfun$apply$3(RetrieveAction.scala:59)     at scala.util.Either.map(Either.scala:382)     at com.mendix.webui.actions.client.RetrieveAction.apply(RetrieveAction.scala:43)     at com.mendix.webui.actions.client.RetrieveAction.apply(RetrieveAction.scala:28)     at com.mendix.webui.actions.client.RegularClientAction$Helpers$.$anonfun$liftEither$1(RegularClientAction.scala:30)     at com.mendix.webui.actions.client.RegularClientAction$Helpers$StateHandler.$anonfun$apply$4(RegularClientAction.scala:56)     at com.mendix.webui.requesthandling.helpers.StateHandling.withState(StateHandling.scala:42)     at com.mendix.webui.requesthandling.helpers.StateHandling.withState$(StateHandling.scala:39)     at com.mendix.webui.actions.client.RegularClientAction$Helpers$StateHandler.withState(RegularClientAction.scala:46)     at com.mendix.webui.actions.client.RegularClientAction$Helpers$StateHandler.apply(RegularClientAction.scala:54)     at com.mendix.webui.actions.client.RegularClientAction$Helpers$StateHandler.apply(RegularClientAction.scala:46)     at com.mendix.webui.actions.client.RegularClientAction.$anonfun$execute$3(RegularClientAction.scala:113)     at scala.util.Try$.apply(Try.scala:210)     at com.mendix.webui.actions.client.RegularClientAction.$anonfun$execute$2(RegularClientAction.scala:113)     at com.mendix.webui.actions.client.RegularClientAction.$anonfun$execute$2$adapted(RegularClientAction.scala:111)     at com.mendix.webui.requesthandling.helpers.ContextHandling.$anonfun$inContext$5(ContextHandling.scala:57)     at scala.runtime.java8.JFunction0$mcV$sp.apply(JFunction0$mcV$sp.scala:18)     at com.mendix.basis.actionmanagement.ActionMonitoring$.$anonfun$monitor$1(ActionMonitoring.scala:49)     at com.mendix.util.classloading.Runner.withContextClassLoader(Runner.java:19)     at com.mendix.basis.actionmanagement.ActionMonitoring$.monitor(ActionMonitoring.scala:49)     at com.mendix.webui.requesthandling.helpers.ContextHandling.inContext(ContextHandling.scala:57)     at com.mendix.webui.requesthandling.helpers.ContextHandling.inContext$(ContextHandling.scala:31)
