To add to Wolfgangs response, you are missing <br>
<br>
public static final int HIGHROADS = 4 <br>
in the Assignment class, also since you are updating Assignment in
the rule actions you should either put NO-LOOP on each of the rules,
or you could use a "trick" to set "lock-on-active" on a package
level (see uploaded xls). With the also uploaded test, the results I
am getting are:<br>
*****<br>
Knowledgebase read<br>
All rules fired<br>
Status: 0<br>
Message: Heavy snow and cold. Medium clearance on main roads<br>
*****<br>
and you can also see the generated DRL (using SpreadsheetCompiler).
Checking the generated DRL of your decision table is useful for
debugging in the future.<br>
<br>
Hope this helps ;)<br>
<br>
Thanks.<br>

Join C8:F8 and change the contents to<br>
a:Assignment() and w:Weather<br>
all conditions deal with Weather - they'll be inserted into the
last pair of parentheses that will be added to Weather. (The "and"
is redundant as it is implied for patterns at the outermost level.
There should be a single Assignment fact, and I guess there is
only one Weather.)<br>
<br>
I would not add an update(a) to each individual action; another
ACTION column with $param; in row nine and "update(a)" in all rows
below lets you remove the repeated "update(a)" from H9:J9. (But
this is, perhaps, a matter of taste.) <br>
<br>
Cheers<br>

PS: Regretfully, this set of rules is going to be late for this
winter ;-)<br>

Hi all,<br>
<br>
I am a brand new user of the Drools-tools and am not quite
comfortable with<br>
the tools yet. The current problem I am having, is caused by
an "Unknown<br>
parsing error" in a decision table.<br>
<br>
>From past experience, I guess I have made a syntax error
somewhere in the<br>
file. However, I am not able to detect the error myself.
Probably it is a<br>
quite simple mistake, caused by a combination of inexperience
and<br>
neglectance :-).<br>
<br>
I figured I could use an extra pair of eyes and was hoping
that some<br>
friendly community member could help me out on this.<br>
<br>
I will annex the table as well as the java code that contains
the java<br>
classes (the table isn't callad from the code yet).<br>
