With expression like \[WW:0\] ... \[WW:3\] etc. WebWork will cut the stack and still returned back a CompoundRoot object. To get the top of that particular stack cut, use [0].top |

Besides the examples and descriptions given above, there are a few major changes in the EL since WebWork 1.x. The biggest one is that properties are no longer accessed with a forward slash \(/\) but with a dot (.). Also, rather than using ".." to traverse down the stack, we now use "\[WW:n\]" where n is some positive number. Lastly, in WebWork 1.x one could access special named objects (the request scope attributes to be exact) by using "@foo", but now special variables are accessed using "#foo". However, it is important to note that "#foo" does NOT access the request attributes. Because XWork is not built only for the web, there is no concept of "request attributes", and thus "#foo" is merely a request to another object in the OgnlContext other than the root. |
