type="cite">Hello,<br>
<br>
Please give me advice for best way storing global variables.<br>
<br>
global java.lang.Integer res;<br>
global java.lang.Integer res2;<br>
...<br>
<br>
I've several number of rules. One rule has variable initialization e.g.:<br>
<br>
...<br>
rule "AmountsAreNotNull" salience 20<br>
when<br>
< conditions ><br>
then<br>
...<br>
res = new Integer(a.compareTo(new BigDecimal(25)));<br>
res = (res == -1)?0:res;
<br>
res = (res == -1)?0:res;<br>
res2 = new Integer(a.compareTo(b));<br>
res2 = (res2 == -1)?0:res2;<br>
...<br>
end<br>
<br>
The values of these variables are proper and equal 1<br>
<br>
Then next rule has comparing for res|res2 values, but they have lost
their values (res == null and res2 == null)
<br>
<br>
rule "CompareValues" salience 10<br>
when<br>
res:Integer(intValue == 0)<br>
res2:Integer(intValue == 0)<br>
result:List()<br>
then<br>
result.add(Boolean.TRUE);<br>
end<br clear="all">
<br>
What decision you can advise me to save variables value between rules?<br>
Thanks.<br>
