Re: Cannot reset buffer after response has been committed && JspViewDeclarationLanguageStrategy
I created an issue after analzing the original problem: https://issues.apache.org/jira/browse/MYFACES-3587 Should i also create an issue because disable SUPPORT_JSP_AND_FACES_EL requires to set the EXPRESSION_FACTORY? Or is it be design? 2012/7/25 Thomas Andraschko > Ah, sorry!

Re: Cannot reset buffer after response has been committed && JspViewDeclarationLanguageStrategy
Ah, sorry! I got another exception now: javax.faces.FacesException: Cannot find a valid PDL for view id null. So the third question is, isn't there any viewId == null check? 2012/7/25 Thomas Andraschko > Hi, > > i get following error if i try to open a page, which does not exist: > Cannot reset buffer after response has been committed > > As far as i can see, the JspViewDeclarationLanguageStrategy handles the > "null" viewId and if i return "false" in #isHandle, it works without > problems. > Why JspViewDeclarationLanguageStrategy handles also the "null" viewId? > > I looked at the code and org.apache.myfaces.SUPPORT_JSP_AND_FACES_EL > should disable the JspViewDeclarationLanguageStrategy, right? > If i set this context param to false, i get follwing exception on startup: > An error occured while initializing MyFaces: No javax.el.ExpressionFactory > found.

Cannot reset buffer after response has been committed && JspViewDeclarationLanguageStrategy
Hi, i get following error if i try to open a page, which does not exist: Cannot reset buffer after response has been committed As far as i can see, the JspViewDeclarationLanguageStrategy handles the "null" viewId and if i return "false" in #isHandle, it works without problems. Why JspViewDeclarationLanguageStrategy handles also the "null" viewId? I looked at the code and org.apache.myfaces.SUPPORT_JSP_AND_FACES_EL should disable the JspViewDeclarationLanguageStrategy, right? If i set this context param to false, i get follwing exception on startup: An error occured while initializing MyFaces: No javax.el.ExpressionFactory found. Please provide in web.xml: org.apache.myfaces.EXPRESSION_FACTORY Why is it required to manually set the ExpressionFactory? We use Jetty on localhost and JUEL/Tomcat on our servers. Thanks! Thomas
