Unlike "Presidents" which uses a local, modified copy of the Exhibit trunk, "Presidents2" loads from api.simile-widgets.org . *Attached, *the 35K Xar (Zip/Jar format) containing the standalone demo, comprising three documents: Exhibit.Presidents2 and data-files Exhibit.PresidentsSchemaJSON and Exhibit.PresidentsJSON. You should be able to import these into your xwiki installation and get a working demo of Exhibit. (note that since the javascript in Exhibit.Presidents2's object XWiki.JavaScriptExtension[2] loads external javascript, the server and the clients accessing must be connected to the network for this to work). *Resolved*, one issue: > One last remaining hack is that I put the following in the headers > >> <link rel="exhibit/data" type="application/json" >> href="$xwiki.getURL("Exhibit.PresidentsSchemaJSON","view","xpage=plain")" /> >> <link rel="exhibit/data" type="application/json" >> href="$xwiki.getURL("Exhibit.PresidentsJSON","view","xpage=plain")" /> >> > via the "Exhibit" space's "HTTP Meta Information" administration setting > ... This is replaced with some JavaScript residing in XWiki.JavaScriptExtension[0]: insertExhibitDataLink(window.document, "/xwiki/bin/view/Exhibit/PresidentsSchemaJSON?xpage=plain"); insertExhibitDataLink(window.document, "/xwiki/bin/view/Exhibit/PresidentsJSON?xpage=plain"); (Next version, Presidents3, will replace loading these two extra javascript files and instead put the javascript data directly into XWiki.JavaScriptExtension[0], replacing insertExhibitDataLink() calls.) *Unresolved*, the IE portability issue, an Exhibit bug?
