BA 6.6 evaluation error in loop

Options

‎03-31-2009 09:37 AM

Hi,

I'm trying to validate data using Blaze Advisor rule repository from Java.
My SRL function :

 

try
{
    apply Representative_Ruleset();
    aCount is an integer initially gGoodsItems.count;
    aIndex is an integer initially 0;
    while (aIndex < aCount) do
    {
        apply GoodsItems_CommodityCode_Ruleset(aIndex);
        apply GoodsItems_Packages_Marks_Ruleset(aIndex);
        aIndex = aIndex + 1;
    }
}
catch a Throwable with
{
    it.printStackTrace();
}

 

It throws a NdServiceSessionRuntimeException in the while loop on exit of the first apply.
Exception disapears if both "apply" in the loop are commented.

 

Full exception trace :

 

com.blazesoft.server.base.NdServiceSessionRuntimeException: Service session Id number 39.
Service 'Decision Services'. Server 'Decision Services' on host 'yyyy'.

Re: BA 6.6 evaluation error in loop

I don't think it has anything to do with the loop. It looks like there is some object that is being manipulated by your ruleset in such way that its hash code changes. As a result, it cannot be found and deleted from the working memory or something along these lines.

 

Check your Java class code to see how the hashCode()/equals() methods are implemented and try to make the object's hash code immutable for the duration of the rule session.

Also for classes that like to change their hashcode there is a way to tell Blaze that they cannot be trusted. Just search for "NdUserDefinedMutableJavaValueClasses.properties" in Blaze HTML documentation.
