Svein commented on TAP5-2489:
-----------------------------
I think you are focusing on the internal coding of the component. I thought
that @Parameter.required() was a constraint for the users of the component.
From the external point of view the parameter is not required, and normally
should never be set on call to the component. A better way is to override the
message:<STRING>. Internally the parameter is required, otherwise the button
will not have any information.
The solution for IntelliJ is to check if the @Parameter.value is set in its
analysis of the usage of the component.
if (required && value == null) then "Analysis error in IntelliJ"
If you agree, should I report this to Jetbrains/IntelliJ, or would you like to
do that?

> Having value = "message:core-palette-available-label" and value =
> "message:core-palette-selected-label" then @Parameter(required = false) is
> better! My IDE gives me error when selectedLabel or availableLabel is skipped.
