Hi all,
Does anyone have a solution to this? I have exactly the same problem. For
example:
<action name="ProductAction_*" method="{1}"
class="jp1980.actions.ProductAction">
<result
name="list">/customer/products/list_ext.jsp</result>
<result name="json_list" type="json">
products, productsTotal
</result>
<result name="error">/error.jsp</result>
<result name="success">/missing.jsp</result>
</action>
products is a List. If I specify products as the root, or specify no root
or includeParams and return everything from my action, products is returned
and populated fine in the JSON. However, if i use the includeParams as
above, products is empty when I inspect the JSON.
Thanks for reading and kind regards,
James

All,
I am having a problem returning collections (or arrays) from struts
action as JSON. All collection-type data comes back empty (map, array,
etc).
Setup:
struts.xml
<package name="json" extends="json-default">
<action name="getPayPlanGradesAjaxCall"
class="com.intellidyne.rms.action.accession.AccessionAction"
method="getPayPlanGradesAjaxCall">
<interceptor-ref name="json">
true
</interceptor-ref>
<result type="json">
true
dutyHours,
payPlanTypes
</result>
</action>
</package
Action:
public class AccessionAction extends BaseAction implements
ConversationScopeAware, ValidationAware
{
private static final long serialVersionUID = -1249579868850221888L;
private String dutyHours;
private List<String> payPlanTypes;
public String getDutyHours()
{
return dutyHours;
}
public void setDutyHours(String dutyHours)
{
this.dutyHours = dutyHours;
}
public final List<String> getPayPlanTypes()
{
return payPlanTypes;
}
public final void setPayPlanTypes(List<String> payPlanTypes)
{
this.payPlanTypes = payPlanTypes;
}
public String getPayPlanGradesAjaxCall()
{
dutyHours="12345";
payPlanTypes = new ArrayList<String>();
payPlanTypes.add("TEST1");
payPlanTypes.add("TEST2");
return SUCCESS;
}
}
JSP:
......
<button dojoType="dijit.form.Button"
label="TEST"
value="Test">
<script type="dojo/method" event="onClick">
console.debug("Getting JSON DATA");
dojo.xhrGet ({
url: "getPayPlanGradesAjaxCall.html",
handleAs: "json",
load: function(response, ioArgs) {
console.debug("Returned from the call. Response is
"+response.dutyHours);
console.debug("Returned content:
"+response.payPlanTypes);
return response;
}
});
</script>
</button>
The button does not do anything besides making AJAX call. Here is the
response in FF Fbug:
{"dutyHours":"12345","payPlanTypes":[]}
Even if I use various dojo methods (such as dojo.toJson, etc) on
response object, the collection is still empty.
I used arrays, maps, whatever. It is still empty.
The main problem I am trying to solve is how to populate one select
from something selected in another. (typical car makes/models scenario)
Please advise, your help is greatly appreciated.
Greg
