Yasser Zamani updated WW-5125:
------------------------------
Priority: Minor (was: Major)
> forbidden name attribute values (size, clone...?) in <s:textfield> using the
> default theme
> ------------------------------------------------------------------------------------------
>
> Key: WW-5125
> URL: https://issues.apache.org/jira/browse/WW-5125
> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.5.26
> Reporter: Patrice DUROUX
> Priority: Minor
> Fix For: 2.6
>
>
> Hi,
> It is easy to reproduce running an (empty) action resulting a simple JSP page
> like this:
> {code:java}
> <%@ taglib prefix="s" uri="/struts-tags"%>
> <!DOCTYPE html>
> <html lang="en">
> <head>
> </head>
> <body>
> <h1>Struts bug2</h1>
> <s:textfield theme="simple" name="clone" />
> <s:textfield name="clone" />
> </body>
> {code}
> The first textfield is rendered but the second throws an exception like:
> {code:java}
> SEVERE: Error executing FreeMarker template
> FreeMarker template error:
> Getting the number of items or listing the items is not supported on this
> method+sequence (wrapper: f.e.b.SimpleMethodModel) value, because this value
> wraps the following Java method, not a real listable value: public
> java.lang.Object java.util.HashMap.clone()----
> Tip: Maybe you should to call this method first and then do something with
> its return value.
> ----
> Tip: obj.someMethod(i) and obj.someMethod[i] does the same for this method,
> hence it's a "+sequence".
> --------
> FTL stack trace ("~" means nesting-related):
