I use DeltaSpike 1.0.0 with MyFaces 2.2.4 and OpenWebBeans 1.2.2 on tomcat 7 (7.0.39). Apart from the fact that this stack performs well and has some nice extras, such as vdl.createComponent, the main advantage I see in using it is that people from those projects work together with those components. So it is easier to get support. I also use PrimeFaces and OmniFaces, but it seems to me that their development is less tightly coupled (especially for omnifaces, as it seems to me that BalusC is glassfish/weld oriented). I can send you my pom.xml if this can help you. Best regards, Ludovic | | AVANT D'IMPRIMER, PENSEZ A L'ENVIRONNEMENT. |
Re: Getting NPE when flowscope value evaluates to null.
Hi
I tried to set the null value with MyFaces 2.2.4 and it works as expected.
But trying with Mojarra 2.2.7 I get this:

Take a look your classpath, probably something is not right.

Getting NPE when Flow Scope parameter evaluates to null.
If no value is entered for firstName before “continue” on
