I've spent the last couple of hours trying to debug a page with mapped properties.
I found a section of the faq about it: http://struts.apache.org/faqs/indexedprops.html
It says: "The signature of the "get" and "set" methods for a mapped property are different from the same methods for an indexed property. In particular, instead of an "int" for the index, there is a "String" for the key." and the example shows these methods...
But this doesnt work!!!!!!!!
That's not true; what is specified there works for the commons-beanutils tool, which is the thing that knows how to find mapped properties with introspection.
To read the field, it requires a get method like: public Map getDate() { return dateMap; }
For it to write the fields it needs a set method like: public void setDate(Map date) { this.dateMap=date; }
This may be the case if you want to use JSTL expressions to retrieve values from the map, as in
<c:out value="${myObj.date['key']" /> but it doesn't impact commons-beanutil's introspection. I know this because I've used "mapped properties" as a cheap way to parameterize date formatting, back before the JSTL and before even the Struts tags supported a 'format' attribute.
public String getFormattedDate(String pattern) {
... typical SimpleDateFormat stuff
}<bean:write name="myObj" property="formattedDate(YYYY-mm-dd)" />
