| jbe/bsw@0 | 4 It is MANDATORY to call this function once in each filter of a WebMCP application. Calling execute.inner() calls the next filter in the filter chain, or the view or action, if there are no more filters following. Code executed BEFORE calling this function is executed BEFORE the view or action, while code executed AFTER calling this function is executed AFTER the view of action. |
