What's the dojo version in spring-js-resources-2.3.1.RELEASE.jar

[javenxu]

I'm using spring-roo-1.2.1 to draw a add order page.I'm want to put the order info field and item list in the same page with pop window edit item info.
for roo have no example similar to my requirement,I read some example in dojotoolkit.org,but I can't find the roo's dojo version‚
dojotoolkit release the version 1.5.0;1.5.1,1.5.2;1.6.2;1.7.2, but dojo not include version info in the file .

I compare the dojo js file,but no one is match.I guess may be spring modify the dojo js.

from version spring-js-resources-2.2.1 to spring-js-resources-2.3.1, spring only modify 2 row code.
I'm new to dojo and can't find suitable dojox.grid.Grid exapme can work with spring-js-resources-2.2.1

for the spring-js-resources-2.3.1.jar was realsed with the web-flow project,
could any one tell me somthing about the dojo in webflow?
