Bug 1218812

Description of problem:

In decision tables we can provide parameters separated by comma and refer to it using the directives $1, $2 etc. However, when trying to get the value $10 it will never work with error or compiling to a bad DRL.

Version-Release number of selected component (if applicable):
N/A.

How reproducible:
Always.

Steps to Reproduce:
1. Create a Spreadsheet decision table
2. In the field action, use the mentioned syntax and try to access the 10th parameter:

System.out.println($10)

3. Provide 10 values:

"One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten"


Actual results:

Error:

Rule Compilation error Syntax error on token "0", delete this token

Expected results:

Print to the 10th parameter.

Additional info:

if we do not use quotes on the parameter, it will not have any error, but will compile to a bad DRL.

Action:

System.out.println("$10")

Value:

One,Two,Three,Four,Five,Six,Seven,Eight,Nine,Ten

It will compile to:

rule "ParamTest"
	// Test parameters more than 9
	when
	then
		System.out.println("One0");
end
