Issue Description:

Under non-executable model and mvel dialect, when modify-block is placed inside a block like if-block in RHS, the modify does not work correctly (rules to be fired by property reactivity are not fired).

    if (<condition>) {
        modify(<fact object>) {
            <property> = <value>
        }
    }

Acceptance Criteria:

TBD

Additional Information:

Test cases may include more variants of modify/update with statement blocks.
Configuration combinations:

• non-exec-model and exec-model
• java dialect and mvel dialect
• modify and update
