Using Parameters

    Parameters in Properties of Components

    When you have defined, for example, a FILTER_EXPRESSION (parameter) which means a filter expression, you can use ${FILTER_EXPRESSION} instead of defining the filter expression in each Filter.

    CTL2 expressions can be used as a parameter value, see Parameters with CTL2 Expressions (Dynamic Parameters).

    Using Parameters in CTL

    If you use parameters in CTL, you should get their value via getParamValue("MyParameter"). Be careful when working with them, you can also use escape sequences for specifying some characters.
