Error description
Custom facelet library throws an exception if the library XML file contains null render-type element ("<renderer-type />"). This results in a parsing error of the TagLib XML and custom tags will not work. Example of an empty renderer-type tag: <tag> <tag-name>myinput</tag-name> <component> <component-type>com.test.MyInput</component-type> <renderer-type /> </component> </tag> This causes the following exception: Caused by: java.lang.Exception: Value Cannot be Empty at org.apache.myfaces.view.facelets.compiler.TagLibraryConfigUn marshallerImpl$LibraryHandler.endElement(TagLibraryConfigUnm arshallerImpl.java:395) at org.apache.xerces.parsers.AbstractSAXParser.endElement(Unkno wn Source) ... This appears to be expected based on the code in TagLibraryConfigUnmarshallerImpl. Need to modify the MyFaces code to continue on without the Exception.
