Dear XWiki Developers, When I try to load my GWT application at the edit panel, and at the edit model firebug will give me velocity parsing error. Here is the error: <a href="" onclick="document.getElementById('xwikierror1').style.display='block'; return false;">Error number 4001 in 4: Error while parsing velocity page xwiki:resources.js Wrapped Exception: Failed to evaluate content with id [xwiki:resources.js]</a><div id="xwikierror1" style="display: none;"><pre class="xwikierror"> Error number 4001 in 4: Error while parsing velocity page xwiki:resources.js Wrapped Exception: Failed to evaluate content with id [xwiki:resources.js] com.xpn.xwiki.XWikiException: Error number 4001 in 4: Error while parsing velocity page xwiki:resources.js Wrapped Exception: Failed to evaluate content with id [xwiki:resources.js] at com.xpn.xwiki.render.XWikiVelocityRenderer.evaluate(XWikiVelocityRenderer.java:122) at com.xpn.xwiki.render.XWikiVelocityRenderer.render(XWikiVelocityRenderer.java:93) at com.xpn.xwiki.render.XWikiVelocityRenderer.interpret(XWikiVelocityRenderer.java:55) at com.xpn.xwiki.render.DefaultXWikiRenderingEngine.renderText(DefaultXWikiRenderingEngine.java:269) at com.xpn.xwiki.render.DefaultXWikiRenderingEngine.interpretText(DefaultXWikiRenderingEngine.java:175) at com.xpn.xwiki.XWiki.parseContent(XWiki.java:1610) at com.xpn.xwiki.web.SkinAction.renderFileFromFilesystem(SkinAction.java:239) at com.xpn.xwiki.web.SkinAction.render(SkinAction.java:133) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:214) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:115) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.wysiwyg.server.filter.ConversionFilter.doFilter(ConversionFilter.java:152) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.web.ActionFilter.doFilter(ActionFilter.java:117) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.plugin.webdav.XWikiDavFilter.doFilter(XWikiDavFilter.java:68) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.web.SavedRequestRestorerFilter.doFilter(SavedRequestRestorerFilter.java:295) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:112) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:859) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:574) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1527) at java.lang.Thread.run(Unknown Source) Wrapped Exception: org.apache.velocity.runtime.parser.TemplateParseException: Encountered &#34;+ markerId + &#34;
