Hi All,
My question is in regard to submitting a JSP form that contains form
fields displayed by iterating over a hashmap.
I have defined a DynaActionForm in my Struts-config file in which, besides
numerous String properties, I have one hashmap.
<form-bean
name="profileform"
dynamic="true"
type="org.apache.struts.action.DynaActionForm">
<form-property
name="...."
type="java.util.String" />
<form-property
name="userFields"
type="java.util.HashMap" />
</form-bean>
Using the "profileForm.set()" method in my ShowAction for displaying the
fields in my JSP form is working fine, including for the hashmap:
ShowAction code Fragment:
HashMap userFields = new HashMap();
[...builds a dynamic set of user field names and field values...]
profileForm.set("userFields", userFields);
JSP code fragment:
<logic:iterate id="userField" name="profileform" property="userFields">
<tr>
<th align="left">
<bean:write name="userField" property="key"/>
</th>
<td align="left">
<html:text name="userField" property="value"/>
</td>
</tr>
</logic:iterate>
Whereas the theory behind handling the String form fields ("dynamic"
setters and getters) seems very straightforward, I don't understand how
the dynamic form handles the hashmap fields (if it is handling them at
all?) on submit. How do I access the edited hashmap field values for
updating my business objects within the SaveAction?
Copying from the successful processing of the form String fields, I have
tried in the SaveAction:
HashMap userFields = (HashMap)profileForm.get("userFields");
but NullPointerExceptions thrown while trying to access 'userFields' lead
me to believe that I am not getting my desired results.
Any guidance would be greatly appreciated.
Thanks,
Susan
