Looks like it might be a Mojarra issue.

mvn clean jetty:run -Pmojarra40 FAILS

mvn clean jetty:run -Pmyfaces40 PASSES

Even with MyFaces 4.0 its kinda slow to react but does end up sorting.

Its also strange its not happening on the Showcase because your code looks identical to the Showcase?

It happens using every template (ultima etc.) demo application on the primefaces site. Get Outlook for Android<https://aka.ms/AAb9ysg>
