A cannot be a fact and a variable at the same time. If you have, say,<br> class Box { String input;... } <br>as a Java class, you'll have to check that input != null and != "" before<br>you check that it contains characters according to a number. (This<br>
could be done in a single rule.)<br><br>But you can't simply the string against numeric limits; you'll have to<br>do a conversion into another field or, preferably, into the application<br>object.<br><br>rule checkInput<br>
when<br> Box( $inp: input == null || == "" || not matches "\\d+" )<br>
then<br> ...error...<br>end<br><br>rule convert<br>
when<br>
Box( $inp: input != null && != "" && matches "\\d+" )<br>
then<br>
insert( new Data( Integer.valueOf( $inp ) ) );<br>
end<br><br>
rule checkRange<br>
when<br>
Data( value < 0 || value > 100 )<br>
then<br>
... error ...<br>
end<br><br>And, most certainly, you don't want to have this executed at the same time.<br><br>-W<br><br>

I see what you mean. You are right, that means when the fact A is<br>
inserted , the rule engine will come up an agenda which is A()<br>
related, right?<br>
<br>
OK, let's take in another way. If A is one of a variable of a Fact<br>
say X(), then only the 3 rules evaluate the A variable of the Fact X()<br>
in the 1000 rules of rulebase. How can I only execute the 3 rules<br>
programmatically?<br>
<br>
In fact, the problem comes from the legacy window program. When we<br>
develop the old window program, we can add lots of field validation of<br>
the field by right clicking the edit box, right? Right now, we need<br>
to migrate to java-based solution and use the BRMS to store those<br>
validation rules. The above 3 rules were put in the validation rules<br>
of the edit field of the window program, and now I put these 3 rules<br>
into the BRMS and revamp the window program frontend to whatever<br>
html/GWT/ZK frontend now.<br>
<br>
If cannot get what I mean, please tell me and I try to describe again.<br>
<br>
<br>
Thank you very much and thanks for your patience.<br>
