Hi,
Kinda new to WW2/XWork, maybe I'm blind, so tell me if I am ;-)
Here is my problem:
We work in our database driven application with a persistence Manager that
abstracts records as objects implementing Map interface - manager is OFBiz
entity engine, for those who might know it...
So, if I want to edit a record and store the result back to db, I have to do
always the same (web environment):
1. Prepend the edit view with an initialized currentObject (a Map) in context
2. Have a jsp with a form in which inputs are presented for the entries in the
currentObject the user might change
3. Have a store action to which the form in 2. submits. Store the values
changed in db again.
The form should read values out of a Map and present them in inputs, ready to
be changed. But how do I manage to have them dispatched back to the / a Map
for the store action, including type conversion???
What I tried till now
EntityAction.java:
public abstract class EntityActions extends ActionSupport {
protected GenericValue currentObject = null; //GenericValue implements Map
public void setCurrentObject(GenericValue object) {..}
public GenericValue getCurrentObject() {..}
...
public String edit () {
// load some GenericValue from db
// or create an empty one and set it as currentObject
..
return SUCCESS;
}
public String store () {
// store the currentObject, which now should contain the edited
// values from our web form
..
if (noError) {
return SUCCESS;
} else {
// Do input again to correct values
return INPUT;
}
}
}
xwork.xml:
...
<action name="edit" class="de.aixcept.tse.action.EntityActions" method="edit"
>
<param name="entity">translations</param>
<result name="success" type="dispatcher">
<param name="location">/WEB-INF/jsp/admin/translation/edit.jsp</param>
</result>
<interceptor-ref name="defaultStack"/>
</action>
<action name="store" class="de.aixcept.tse.action.EntityActions"
method="store" >
<param name="entity">translations</param>
<result name="input" type="dispatcher">
<param name="location">/WEB-INF/jsp/admin/translation/edit.jsp</param>
</result>
<result name="success" type="chain">
<param name="actionName">edit</param>
</result>
<interceptor-ref name="defaultStack"/>
</action>
...
edit.jsp:
..
<ww:form action="store.action" method="POST" >
<ww:textfield label="English :" name="???"
value="#currentObject.get('en')" />
<ww:textfield label="German :" name="???"
value="#currentObject.get('de')" />
<ww:submit name="storeTrans" />
</ww:form>
..
I hope I could explain what I mean...
Is it possible to dispatch the form parameters back again to currentObject for
store action, including type conversion? Such as
Action:
private Long myNumber = null;
public Long getMyNumber()
public void setMyNumber(Long aNumber)
...
form:
<ww:textfield label="My Number :" name="myNumber" />
...
which will do everything automagically when parameters interceptor is in
place?
Can someone help (if anyone understood what I try to do :-) ??
Regards,
Rene
