Error
The method setVar(String) in the type DataTableTag is not applicable for the arguments (JspValueExpression)
while using
Tomcat: 6.0.16
JSF: Sun's JavaServer Faces implementation (1.2-b20-FCS)
Cause
The root cause of this issue is, the definition of the "var" attribute of the dataTable tag in "html_basic.tld" does not match with signature of "setVar" method on com.sun.faces.taglib.html_basic com.sun.faces.taglib.html_basic.DataTableTag class.
The definition of "var" in the tag lib file is a "deferred-value" of type "java.lang.String"
which tells that JSP compiler that this is a "ValueExpression", hence it generates the following code
setVar(new org.apache.jasper.el.JspValueExpression("/HelloWorld.jsp(12,1) 'currentItem'",_el_expressionfactory.createValueExpression("currentItem",java.lang.String.class))
where as, the DataTableTag class expects setVar(String).
Workaround
Use a previous stable build. I used "jsf-1.2_07-b03-FCS".

Thanks, this has saved me a great deal of grief, the problem is version 1.2-b20-FCS is the default one that is shown when I get forwarded to the jsf download page. I downloaded version 1.2_09-b02-FCS, but that was still broken. I downloaded jsf-1.2_07-b03-FCS and it worked as you said. I wonder if any one has raised this with Sun yet!
where would I go to get that version of JSF? I am having the same problem with the current version
Muchas gracias, me salvaste!
thanks a lot, you save me!
Thanks a lot, jsf-1.2_07-b03-FCS is a solution, but i have another solution which is to change your web server to glassfish.
But the first one is better
jsf-1.2_07-b03-FCS:
