(Updated Dec. 18, 2012, 6:59 a.m.) Review request for shindig, Ryan Baxter, Dan Dumont, Stanton Sievers, and Rich Thompson. Changes ------- Update and verify it in lastest code. Description ------- Copied from https://reviews.apache.org/r/6695/ The OpenSocial 2.0 specification now states that the old way of doing variable subsitution is now deprecated in favor of using EL syntax. Add that support to Shindig. For example, Gadget developer should be able to to use EL syntax to 1. Calculate value like ${1+2} 2. get user preference values anywhere in the gadget XML by ${UserPrefs.xxx} This addresses bug shindig-1588. https://issues.apache.org/jira/browse/shindig-1588 Diffs (updated) ----- http://svn.apache.org/repos/asf/shindig/trunk/content/samplecontainer/examples/ELInGadgetDemo.xml PRE-CREATION http://svn.apache.org/repos/asf/shindig/trunk/content/samplecontainer/examples/commoncontainer/gadgetCollections.json 1417305 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/render/RenderingGadgetRewriter.java 1417305 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/templates/DefaultTemplateProcessor.java 1417305 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/test/java/org/apache/shindig/gadgets/render/RenderingGadgetRewriterTest.java 1417305 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/test/java/org/apache/shindig/gadgets/templates/DefaultTemplateProcessorTest.java 1417305 Diff: https://reviews.apache.org/r/8184/diff/ Testing ------- Upload a Test Gadget with this patch Thanks, Zhi Hong Yang
