PrimeFaces 5.3 with MyFaces 2.2.12

[surajit.pal]

Hi,
I am using PrimeFaces 5.3 with MyFaces 2.2.12 and Spring Webflow 2.4.4.RELEASE. During runtime, I am getting the following error:

I am not using mobile tags in my application. So, I don't have any clue why it is trying to call org.primefaces.mobile.event.system.CalendarResourceListener.processEvent

I don't have any calendar component in this page. So, don't have any clue why is it happening. Any help would be greatly appreciated.

[tandraschko]

This should never occur - maybe its related to Spring WebFlow but the renderkitId of the current view must not be null!
However you can try 6.1.RC1 - I also fixed this possible NPE for the upcoming RC2.

[surajit.pal]

Hi,
Thanks for your prompt response. I tried with 6.1.RC1 and got the same error. I'll correct a statement I made in the previous post. I said I didn't have any calendar component in that page. In fact, I do have a calendar component in the page. When I remove it, the error goes away. So, it is caused by calendar component.
But I am getting a new error for dataTable given below.

My dataTable has rowKey defined and the application works without any issue with v 3.4.2. It seems the newer versions are not compatible with Spring Webflow. Let me know if there is any workaround available. Otherwise, migrating from Spring Webflow to pure JSF 2.2 would be a substantial effor.
Thank you.

[tandraschko]

PrimeFaces doesn't have an "extra support" for WebFlow. Its up to WebFlow to integrate in JSF and PrimeFaces is compatible with JSF 2.0-2.3.

Please try to debug whats the reason for this exception in your case.
