Edson, I sent this reply to you directly a week ago but it timed today
(now).<br>
<br>
I have no idea what is causing this so it's pretty much impossible for
me to create a self contained test. I can send you an installer for our
application with instructions so you can replicate the problem. I
couldn't post it in public.<br>
<br>

Can you provide a self contained test to reproduce the problem and
attach it to a JIRA? I will fix it.<br>
<br>
Thanks<br>

I am seeing the same ReteTuple.get( Declaration ) NPE when I run the
app with both 4.0.7 jars.<br>
If this is a known bug, it appears not to have been fixed in this
version.<br>

yes, the error in a test would stop the build process. Use the skip
option I mentioned in my other e-mail.<br>

After the build, you can find the jars in:<br>
<br>
drools-core/target<br>
drools-compiler/target<br>
<br>
Their version must always match or you will end up with other
problems.<br>

Nope, only source code. <br>
Problem is 4.0.x will be released as 4.0.7, and if your specific
problem is fixed and you are not able to test before the release, it
will have to wait <a moz-do-not-send="true" href="http://4.0.8."
target="_blank">4.0.8.</a><br>
<br>
All you need to build drools is java, maven and ant. Can you set
this up?<br>

<div bgcolor="#ffffff" text="#000000">Glad to hear
that.
However, I am not set up to do my own drools build
and it looks like the link you sent is for the source. Is there a set
of jars for 4.0.x that I can test from? Here is what I am using now:<br>
<blockquote>antlr-runtime-3.0.jar<br>
core-3.2.3.v_686_R32x.jar<br>
drools-compiler-4.0.4.jar<br>
drools-core-4.0.4.jar<br>
mvel14-1.2.21.jar<br>
xstream-1.2.2.jar<br>

I believe this is fixed already. Can you try it out and let us know?<br>

I am getting this exception after the debugger shows execution has gone

ReteTuple.get(Descriptor). I believe the descriptor argument is null.
Can anyone suggest why this might be happening and what I can do to
