With the assistance of Philippe Riand<\/a> I was able to shorten the original idea<\/a> of canceling a partial refresh to a single SSJS function.\u00a0 By setting the HTTP header „X-XspRefreshId<\/em>“ to „@none<\/em>“ it is possible to get the same result as in the posting before, but there is no „Dojo hack“ required.<\/p>\n

function cancelPartialRefresh(){\r\n   var response = facesContext.getExternalContext()\r\n      .getResponse();\r\n\u00a0\u00a0 response.setHeader(\"X-XspRefreshId\", \"@none\");\r\n\u00a0\u00a0 response.reset();\r\n\u00a0\u00a0 response.commitResponse();\r\n\u00a0\u00a0 facesContext.responseComplete();\r\n}<\/pre>\n
To use this function you just have to call it.\u00a0 Here is the same example like in the previous posting:<\/p>\n
<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<xp:view xmlns:xp=\"http:\/\/www.ibm.com\/xsp\/core\">\r\n   <xp:button value=\"Label\" id=\"button1\">\r\n      <xp:eventHandler event=\"onclick\" submit=\"true\"\r\n         refreshMode=\"partial\" refreshId=\"label1\">\r\n      <\/xp:eventHandler>\r\n   <\/xp:button>\r\n   <xp:br\/><xp:br\/>\r\n   <xp:label id=\"label1\">\r\n      <xp:this.value>\r\n      <![CDATA[#{javascript:\r\n      function cancelPartialRefresh(){\r\n         var response = facesContext.getExternalContext()\r\n            .getResponse();\r\n         response.setHeader(\"X-XspRefreshId\", \"@none\");\r\n         response.reset();\r\n         response.commitResponse();\r\n         facesContext.responseComplete();\r\n      }\r\n\r\n\u00a0     var ajax = new com.ibm.xsp.ajax.AjaxUtil();\r\n      if( ajax.isAjaxPartialRefresh(facesContext) == true){\r\n         cancelPartialRefresh();\r\n         return; \/\/ stop execution of SSJS code\r\n      }\r\n      java.lang.System.currentTimeMillis();}]]>\r\n      <\/xp:this.value>\r\n   <\/xp:label>\r\n<\/xp:view><\/pre>\n
I have added the code to the XSnippet Contest<\/a>. Here is the link to the XSnippet: http:\/\/openntf.org\/XSnippets.nsf\/snippet.xsp?id=cancel-partial-refresh<\/a><\/p>\n
