Better handling of PivotTable misconfiguration #3823

Closed knstvk closed 4 days ago

knstvk commented 3 weeks ago

Jmix 2.4.0

Add a pivot table to a view and connect to a data container:

<pvttbl:pivotTable dataContainer="operationsDc"/>

You will get an NPE at runtime:

java.lang.NullPointerException: Cannot invoke "java.util.Map.entrySet()" because the return value of "io.jmix.pivottableflowui.kit.component.model.PivotTableOptions.getProperties()" is null
    at io.jmix.pivottableflowui.kit.component.JmixPivotTable.lambda$performUpdateItems$5(JmixPivotTable.java:829)

This is what a user will do when using the component for the first time. Let's handle this error and show something more friendly than NPE.
