After rendering the view (HtmlDialog), my Desinger's console always has this error (v5.0.8):

NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config Error during rendering of html dialog ''

On console log, I see on "request" column, it shows "/ivy/faces/instances/144.../RES_NOT _FOUND"

And, stacktrace is bellow:

java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config at org.apache.myfaces.view.jsp.JspViewDeclarationLanguage.buildView( at org.apache.myfaces.lifecycle.RenderResponseExecutor.execute( at org.apache.myfaces.lifecycle.LifecycleImpl.render( at org.apache.myfaces.extensions.validator.core.startup.ExtValLifecycleWrapper.render( at javax.faces.webapp.FacesServlet.service( at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter( at org.apache.catalina.core.ApplicationFilterChain.doFilter( at org.primefaces.webapp.filter.FileUploadFilter.doFilter( ...

But the screen is rendered well on the browsers

How can i solve it? Thanks

Can you attach the full stacktrace of the exception so that we have more information to analyse the issue?

I've got this problem while trying to use a object of a Attribute which is not initaliezed.

for example use of an value request.person.surname

in my case I needed to initialize the sub object in a script step.

hope this helps

Thanks roland, it seems your answer is correct. Maybe Ivy just initialize the sub object before using it in script steps only, while rendering the view, it doesn't.
