Today I wanted to add an attribute to the <BODY> element of my XPage. My goal was to generate HTML code like this:<\/p>\n

<body role=\"document<\/a>\"><\/code><\/pre>\n
After some testing I found a solution by overwriting the method encodeHtmlBodyStart<\/em>. To do this, you have to extend the class ViewRootRendererEx2<\/em>:<\/p>\n
package ch.hasselba.xpages;\r\n\r\nimport java.io.IOException;\r\nimport javax.faces.context.FacesContext;\r\nimport javax.faces.context.ResponseWriter;\r\nimport com.ibm.xsp.component.UIViewRootEx;\r\nimport com.ibm.xsp.renderkit.html_basic.ViewRootRendererEx2;\r\n\r\npublic class MyViewRootRenderer extends ViewRootRendererEx2 {\r\n\r\n\u00a0\u00a0 \u00a0@Override\r\n\u00a0\u00a0 \u00a0protected void encodeHtmlBodyStart(FacesContext fc, UIViewRootEx uiRoot,\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0ResponseWriter writer) throws IOException {\r\n\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0writer.startElement(\"body\", uiRoot);\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0writer.writeAttribute(\"role\", \"document\", \"role\");\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0writeln(writer);\r\n\u00a0\u00a0 \u00a0}\r\n\r\n}<\/code><\/pre>\n
To activate it you have to change the renderer class in the faces-config.xml<\/em>:<\/p>\n
<faces-config>  \r\n  <render-kit>\r\n    <renderer>\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 <component-family>javax.faces.ViewRoot<\/component-family>\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 <renderer-type>com.ibm.xsp.ViewRootEx<\/renderer-type>\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 <renderer-class>ch.hasselba.xpages.MyViewRootRenderer<\/renderer-class>\r\n\u00a0\u00a0\u00a0 <\/renderer>\r\n  <\/render-kit>\r\n<\/faces-config>\r\n<\/code><\/pre>\n
Now, the attribute is added correctly to my HTML code:<\/p>\n
