<br> There was a limitation on MVEL on using constants as keys. I know it was fixed, but not sure about the version. Which specific version of MVEL are you using? (1.3.xx)<br><br> Edson<br><br><div class="gmail_quote">

Hi all!<br>
<br>
I'm writing a rule that contains the following statement:<br>
<br>
$agreementOffer:AgreementOffer($logicalFixedNumber:configurationParameters["6410"])<br>
<br>
This results of this is not surprisingly that both $agreementOffer and<br>
$logicalFixedNumber get assigned a value.<br>
Instead of using the "magic value" 6410, I want to use ParameterId constant<br>
class, which implements the toString() to return the value.<br>
<br>
I have tried several different ways to refer to the constant but without<br>
luck. The errors says:<br>
<br>
Unable to create Field Extractor for<br>
'configurationParameters[ParameterId.LOGICAL_NUMBER_FIXED]<br>
I have also tried to extract the value of the<br>
ParameterId.LOGICAL_NUMBER_FIXED into a local variable, which I can see<br>
prints the correct value, but the error says the same:<br>
<br>
Unable to create Field Extractor for<br>
'configurationParameters[$logicalNumberFixedConstant]<br>
<br>
Do anyone understand what is happening here and what I do wrong?<br>
<br>
I'm are still on the JKD 1.4, and uses MVEL 1.3<br>
<br>
Thanks,<br>
<br>
