Hello, I am having an issue where I see alot of posts but with no resolution stated. I was running Jboss 4.2.2 with myfaces 1.1.5. Everything worked fine. So I tried to bring in Seam 2.0.2 and it seems like it requires myfaces 1.2. So I upgraded myfaces to 1.2.3, but I get errors such as below when my jsp page is rendered. Caused by: org.apache.jasper.JasperException: Unable to convert string "en" to c lass "javax.el.ValueExpression" for attribute "locale": Property Editor not regi stered with the PropertyEditorManager at org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEdito rManager(JspRuntimeLibrary.java:887) I am using myfaces 1.2.3 and jsp-api 2.1 and jstl 1.2 and the myfaces tag that causes this is: <f:view locale="en"> Any pointers would be appreciated... -- View this message in context: http://www.nabble.com/myfaces-1.2.3-issue-with-jboss-4.2.2-and-Seam-2.0.2...
