[jira] [Commented] (WW-5125) forbidden name attribute values (size,
clone...?) in using the default theme
[ https://issues.apache.org/jira/browse/WW-5125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17329350#comment-17329350 ]
Yasser Zamani commented on WW-5125:
-----------------------------------
Thanks very good catch! Looks like we must try if [faq_simple_map|https://freemarker.apache.org/docs/app_faq.html#faq_simple_map] is applicable with backward compatibility. That being said it's a Freemarker behavior: "When I list the contents of a map (a hash) with {{?keys}}/{{?values}}, I get the {{java.util.Map}} methods mixed with the real map entries. Of course, I only want to get the map entries." from mentioned link above.

> Affects Versions: 2.5.26
> Reporter: Patrice DUROUX
> Priority: Major
> Fix For: 2.5.27, 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".
