shouldApplyOgnlBooleanFix

protected boolean shouldApplyOgnlBooleanFix()

Determines whether a fix should be applied to OGNL in order to evaluate Strings as booleans in the same way as Thymeleaf does ('false', 'off' and 'no' are actually "false" instead of OGNL's default "true").

Returns:

whether the OGNL boolean fix should be applied or not.
