Rule name length hard limit of 60 characters?

[David Weir]

Using drools 6.2.0-final.

If I create a rule with a name longer than 60 characters, I get this error:

  text=[ERR 105] Line 916:8 required (...)+ loop did not match anything at input ''], Message [id=2, level=ERROR, path=<MY_RULES_FILE>, line=922, column=0

The docs say that "Best practice is to keep rule names relatively short, i.e. under 60 characters." 

This seems like a suggestion, not a hard limit.

Is this a hard limit?

David.

I have a similar problem when I have this condition:

    not( 

    State( state == "5eb9e666d579a46a7b633cf9c54f0513-4feb219ba036e807162ad9e165a38c32" )   ) 

I get this error:

  text=[ERR 105] Line 922:23 required (...)+ loop did not match anything at input ''], Message [id=3, level=ERROR, path=<MY_RULES_FILE>, line=924, column=0

So is there a mysterious 60 character limit floating around?

never mind. problem caused by unmatched "

Hi David,

where did you read that sentence about keeping rule names short? I cannot find it in our docs.

Javadocs on org.drools.compiler.lang.api.RuleDescrBuilder.name(String n)

I’m building my drl files programmatically and came across this little nugget:

The name of the rule. Best practice is to keep rule names relatively short, i.e. under 60 characters.

Parameters:
