Re: Problem with map-based property in ActionForm

[Scott Van Wart]

Hmm... I tried a number of variations.  The example in the documentation 
you listed seems to include the bean as <jsp:useBean.../> as opposed to 
me implicitly using the myForm bean declared by <html:form action...>.  
I noticed the error message mentions 
'org.apache.struts.taglib.html.BEAN' rather than the MyForm class.  The 
variations I tried included "getKey( String key )", and "getValues( 
String key )", but neither worked.

I'm going to try something a little different to isolate the mapped 
property.  Rather than accessing the property directly I'll try 
extracting the map first:

<c:set var="values" value="${myForm.values}" />

Thanks for the info though, very valuable.  I think the problem with my 
last idea was the whole form->map->key which might need to be shortened 
to form->key, but I'll let you know how I make out.

Thanks,
 Scott

See: http://struts.apache.org/1.2.9/faqs/indexedprops.html

I think it remains for you to provide a method a la:

 public Object getKey(String key) {
 return values.get(key);
}

Subject: Problem with map-based property in ActionForm

I have an action form defined like this:

public MyForm extends ActionForm {
  private Map<String, String> values = new TreeMap<String, String>();
  public Map<String, String> getValues() { return this.values; }
  public Set<String> getKeys() { return this.values.keySet(); }
}

  and in my JSP,

<c:forEach item="key" items="${myForm.keys}">
  <html:multibox property="values(${key})" 
value="first">First</html:multibox>
  <html:multibox property="values(${key})" 
value="second">Second</html:multibox>
  <!-- ... -->
</c:forEach>

When I access the page, I get the following error:

"No getter method available for property permissions(1) for bean under 
name org.apache.struts.taglib.html.BEAN"

  Is this the right way to access map properties in a bean?  Any ideas?

Thanks,
  Scott
