Hi,
I m a little bit confused about the struts 2 set and property tags with
scope attributes. I ran the following test consisting of setting struts
variables in each stack and retrieving it through s:property tag.
You can see that the Page variables only be retrieved through the $ jsp
specification character; furthermore isn t that a little fuzzy for the jsp
developer to retrieve a value seeing the result of the test ?
What about making s:property working such $ jsps specification tag (adding
it the actions operations access) and resolving in all stacksw/scope ? Is
there something I m missing ?
