Forgive me if this one comes through a second time but I seem to be having a few difficulties getting my mails to go through.

Hi Guys,

I've decided to bite the bullet and try and move up to 4.01 but I'm having trouble getting the rules to compile. I have the following drl

/*******************
Code type rules
********************/
package au.com.codeprotechnology.online.ejb3.logic.common

import au.com.codeprotechnology.online.bi.exception.ValidationError
import au.com.codeprotechnology.online.ejb3.logic.constants.CodeTypeConstants
import au.com.codeprotechnology.online.persistence.ejb.core.CodeType

expander common.dsl

rule "Code type is mandatory"

    when
        The code types type is null or empty
    then
        Send the message that the code types type is mandatory
end

rule "Long name is mandatory"

    when
        The code types long name is null or empty
    then
        Send the message that the code types long name is mandatory

end

rule "Short name is mandatory"

    when
        The code types short name is null or empty
    then
        Send the message that the code types short name is mandatory

end

rule "Short name too long"

    when
        The short name for the code type is too long
    then
        Send the message that the code types short name is too long
       
end

rule "Sort order is mandatory"

    when
        The code types sort order is null or zero
    then
        Send the message that the code types sort order is mandatory

end


With the corresponding dsl

But I keep getting the following errors when trying to build the package

unknown:14:36 Unexpected token 'val'
unknown:14:60 Unexpected token ')'
unknown:14:61 Unexpected token '.'
unknown:14:71 mismatched token: [@106,457:458='==',<75>,14:71]; expecting type THEN
unknown:23:36 Unexpected token 'val'
unknown:23:60 Unexpected token ')'
unknown:23:61 Unexpected token '.'
unknown:23:71 mismatched token: [@171,723:724='==',<75>,23:71]; expecting type THEN
unknown:33:37 Unexpected token 'val'
unknown:33:61 Unexpected token ')'
unknown:33:62 Unexpected token '.'
unknown:33:72 mismatched token: [@236,995:996='==',<75>,33:72]; expecting type THEN
unknown:53:37 Unexpected token 'val'
unknown:53:66 Unexpected token ')'
unknown:53:68 Unexpected token '=='

These are the errors from PackageBuilder. Used to work fine with 3 and I can't see any drastic differences between this and your examples in the documentation.
