I'm trying to use the Primefaces-Extensions library in a Liferay JSF Portlet that is already using primefaces 4.0.

When I include any pe component, e.g a <pe:timer>, I get this error:

javax.faces.view.facelets.TagException: /html/editDoc/myProjects.xhtml @32,39 <pe:timer> Tag Library supports namespace: http://primefaces.org/ui/extensions, but no tag was defined for name: timer
at com.sun.faces.facelets.compiler.CompilationManager.pushTag(CompilationManager.java:304)
at com.sun.faces.facelets.compiler.SAXCompiler$CompilationHandler.startElement(SAXCompiler.java:255)
at com.sun.faces.facelets.compiler.SAXCompiler.doCompile(SAXCompiler.java:423)
at com.sun.faces.facelets.compiler.SAXCompiler.doCompile(SAXCompiler.java:399)
at com.sun.faces.facelets.compiler.Compiler.compile(Compiler.java:124)

The only component I've managed to use without crashing is pe:ckEditor, which is however rendering as an inputTextarea (no toolbox etc)

I probably did something wrong setting up the primefaces-extensions library, but I don't know where to look.

I'm using: Liferay 6.2.2 ce primefaces 4.0 primefaces-extensions 1.2.1 (I guess this is the proper version to work with pf 4.0)

About the steps I followed: (I had a perfectly working pf 4.0 setup)

  • Added libs in [portlet docroot]/WEB-INF/lib/ :

    • primefaces-extensions-1.2.1.jar
    • resources-ckeditor-1.2.1.jar
    • commons-lang3-3.1.jar
    • gson-2.2.4.jar

  • Added xmlns:pe="http://primefaces.org/ui/extensions in xhtml file's namespaces

I had the same problem to solve it, you should have 3 jars: commons-lang3-3.1.jar gson-2.2.4.jar primefaces-extensions-2.1.0.jar

!!! you can find in the internet other version of PFE 3..., don't use it, because it's not compatible with the other jars
