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 on
ly 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.</p><div class="table-wrap"><table class="confluenceTable"><tbody><tr><th colspan="1" rowspan="1" class="confluenceTh"><p>Old Expression</p></th><th colspan="1" rowspan="1" class="confluenceTh"><p>New Expression</p></th></tr><tr><td colspan="1" rowspan="1" class="confluenceTd"><p>foo/blah</p></td><td colspan="1" rowspan="1" class="confluenceTd"><p>foo.blah</p></td></tr><tr><td colspan="1" rowspan="1" class="confluenceTd"><p>foo/someMethod()</p></td><td colspan="1" rowspan="1" class="confluenceTd"><p>foo.someMethod()</p></td></tr><tr><td colspan="1" rowspan="1" class="confluenceTd"><p>../bar/blah</p></td><td colspan="1" rowspan="1" class="confluenceTd"><p>[1].bar.blah</p></td></tr><tr><td colspan="1" rowspan="1" class="confluenceTd"><p>@baz</p></td><td colspan="1" rowspan="1" class="confluenceTd"><p>not directly supported, but #baz

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 "[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 on
