Re: [rules-users] NullPointerException when updating a fact

So far I have stuck with 5.3.0. It's not perfect, but I have found it pretty good and reliable. I think that 5.4.0 was a reasonable improvement, but I haven't used it in anger. For me, there wasn't enough improvement in it from 5.3 to merit spending time on an upgrade, so I was waiting for 5.5.0. Maybe others could chime in on that one. I did spend time upgrading my 5.3 project to 5.5.0, because it looked so promising. But I encountered several critical bugs which meant that large chunks of Guvnor functionality just didn't work. I fell back to 5.3.0 again. I'm really hoping to see 5.5.1 before too long, but I think that it has been "a couple of weeks away" for the past 6 months, so I'm not holding my breath. :) Given the extent of change in 6, I wouldn't recommend going anywhere near it unless you're just tinkering with it in your own time to see where things are going. I'm doing that myself at the moment, but it's hard work given the lack of documentation or books. I suspect that we'll be hit by a big wave of books on it before long! So I guess that if I was starting a new project for a client, I would probably go with 5.4.0.Final. Steve On 30 Jul 2013, at 15:18, schenka7 <eugen.berenstein(a)gmail.com&gt; wrote:
