> ActionMessages.getSortedProperties() needed
> -------------------------------------------
>
> Key: STR-1728
> URL: http://issues.apache.org/struts/browse/STR-1728
> Project: Struts 1
> Issue Type: Improvement
> Components: Core, Taglibs
> Affects Versions: 1.1 Final
> Environment: Operating System: other
> Platform: Other
> Reporter: Quande Ren
> Priority: Minor
>
> The <html:errors/> tag will output the standard error information, the error
> order is defined by the order of properties in the validation.xml.
> However, the <html:errors/> is not smart enough. I want to have my own error
> output tag like <mytag:errors/>. I still want to keep the same order for the
> properties. but the ActionMessages.properties() returns unsorted properties.
> there's no way to get the sorted properties.
> I suggest that we add another method called ActionMessages.getSortedProperties
> (), the code can be like this:
> public Iterator getSortedProperties()
> {
> if(this.messages.isEmpty())
> return Collections.EMPTY_LIST.iterator();
> ArrayList keys = new ArrayList();
> for(Iterator i = this.messages.keySet().iterator(); i.hasNext(); ){
> keys.add(i.next());
> }
> Collections.sort(keys,new Comparator() {
> public int compare(Object o1, Object o2) {
> ActionMessageItem v1=(ActionMessageItem)messages.get(o1);
> ActionMessageItem v2=(ActionMessageItem)messages.get(o2);
> return v1.getOrder()-v2.getOrder();
> }
> });
> return keys.iterator();
> }
