[rules-users] jaxb generated fact loaded into Guvnor throws errors when using the ' is contained in the comma separated list' operator

[Sreeram.Vadlamudi at wellsfargo.com]

Hi Mike,

Thank You for your responses.

My apologies.

I did miss copying the closing bracket.the issue still exists though . I suspect whether the way the code has been generated by jaxb has anything to do with it.

In the xml, the field is all upper case as
<xs:element type="xs:string" name="ACTIVITYCODE"/>

I see that JAXB generated the code as follows.

@XmlElement(name = "ACTIVITYCODE", required = true)
    protected String activitycode;

  /**
     * Gets the value of the activitycode property.
     *
     * @return
     *     possible object is
     *     {@link String }
     *
     */
    public String getACTIVITYCODE() {
        return activitycode;
    }

    /**
     * Sets the value of the activitycode property.
     *
     * @param value
     *     allowed object is
     *     {@link String }
     *
     */
    public void setACTIVITYCODE(String value) {
        this.activitycode = value;
    }

rule "Row 1 dds"
           ruleflow-group "None"
           dialect "mvel"
when
factClass : FACTCLASS( ACTIVITYCODE in ("A", "B"))

Unless you have copied and pasted incorrectly, the rule should read:-
3.      |       rule "Row 1 dds"
4.      |           ruleflow-group "None"
5.      |           dialect "mvel"
6.      |           when
7.      |               factClass : FACTCLASS( ACTIVITYCODE in ("A", "B") ) \\<0--- note closing bracket
8.      |           then
9.      |               factClass.setRATE( "5.25" );
10.     |       end

There is a closing bracket missing in the generated DRL.

This is a bug. Please raise a JIRA and assign to me and I'll fix for 5.3.0.Beta1.

With kind regards,

Hello ,

I am using 5.2.0.CR1 version of Guvnor .

I have a jaxb generated class loaded through the model jar into Guvnor to be used as a fact in the Guided Decision Table editor.

When I use a field ACTIVITYCODE  of type String from the JAXB generated class  with  ' is contained in the comma separated list'  operator, I get compilation errors.

Unable to Analyse Expression ACTIVITYCODE == "A" || ACTIVITYCODE == "B": [Error: no such identifier: ACTIVITYCODE] [Near : {... ACTIVITYCODE == "A" || ACTIVI ....}] ^ [Line: 1, Column: 1]

But when I use equal to operator to compare value to just a string value, it compiles fine.

This rule fails.

3.      |       rule "Row 1 dds"
4.      |           ruleflow-group "None"
5.      |           dialect "mvel"
6.      |           when
7.      |               factClass : FACTCLASS( ACTIVITYCODE in ("A", "B")
8.      |           then
9.      |               factClass.setRATE( "5.25" );
10.     |       end

The below rule compiles fine.


3.      |       rule "Row 1 dds"
4.      |           ruleflow-group "None"
5.      |           dialect "mvel"
6.      |           when
7.      |               factClass : FACTCLASS ( ACTIVITYCODE =="A")
8.      |           then
9.      |               factClass.setRATE( "5.25" );
10.     |       end

Is this issue being caused by jaxb generated class? If so, is there a way to fix this problem?

When I use a regular pojo that is not jaxb generated, the

is contained in the comma separated list'  operator works fine.

Can someone provide any direction or thoughts on this?

Thanks,

Ram
