this.valueStackFactory is null

[Håkan Andersson <ha...@evertiq.com.INVALID>]

Hi

I'm using Struts with Guice and in Struts 6.x.x I get 
NullPointerException, but it works fine in earlier versions of Struts. 
Is there anything I missed regarding the upgrade?

Do you use some plugin? If so the plugin must be adjusted to changed
architecture of Struts 2 (hence major version change from 2.5 to 6.x)
