tag and DynaActionForm

["Poppe, Troy" <Tr...@eia.doe.gov>]

I have an <html:image> tag inside a <html:form> tag, which points to one of my
Struts Actions.  My Action utilizes a DynaActionForm, in which I have defined
several form-property entries.  One of these form-property entries, lets call it
"imageProperty" matches the property attribute of my <html:image> tag, also
"imageProperty".

However, in my Action, when I have clicked on the image generated by the
<html:image> tag, the DynaActionForm object does NOT contain an entry for the
<html:image> property attribute.

I would expect that my call to dynaForm.get("imageProperty") would return
something other than throwing an IllegalArgumentException.

Here's the HTML:

<html:form action="myAction">
  <html:image page="/img/myImage.gif" property="imageProperty" />
</html:form>

The struts-config.xml:

<form-bean dynamic="true" name="myActionForm"
type="org.apache.struts.action.DynaActionForm" >
  <form-property name="imageProperty" type="java.lang.String" />
</form-bean>

<action attribute="myActionForm" name="myActionForm" path="/myAction"
type="com.foo.bar.MyAction" validate="false">
    <forward ... />
</action>

The Action code:

....

  DynaActionForm dynaForm = (DynaActionForm) form;
  if ( dynaForm != null )
  {
    Object o = dynaForm.get("imageProperty");
  }

....

Any thoughts on what I am doing wrong here?

You should probably use something like an ImageButtonBean [1] instead of
a String. And make sure you have not set the value property [2].
