xml DataSources and DMI

[pferraiolo]

I am having a problem using an xml DataSource bound to a serverObject. The DataSource looks like this:

<DataSource
ID="searchObject"
dataFormat="xml"
serverType="generic"
addGlobalId="true"
recordXPath="//SearchObject"
>
<fields>
<field name="Id" type="text" hidden="true" primaryKey="true" />
<field name="SearchTarget" hidden="true" type="text" required="true" />
<field name="Name" type="text" title="name" required="true"/>
<field name="DisplayString" hidden="true" type="text" />
</fields>
<serverObject ID="searchObjectHandler" lookupStyle="new" className="com.daylight.port.shared.dmi.SearchObjectDMI" />
</DataSource>

This is bound to a ListGrid:

isc.ListGrid.create({
ID: "mySearches",
width: "100%",
height: "125px",
autoFetchData: true,
alternateRecordStyles:true,
showAllRecords:true,
selectionType: "single",
cellHeight:22,
// canEdit:false,
useAllDataSourceFields: true,
dataSource: "searchObject"
}),
The add method on the DMI server object looks like this:

public String add(HttpSession session, Map<?,?> values) throws Throwable {
log.info("procesing SearchObjectDMI add operation");
ObjectManagerFinder finder = DayportObjectManagerFinder.getFinder(session);
PersistentObjectManager pom = finder.getObjectManager(session);
String searchTarget = (String)values.get("SearchTarget");
SearchManager manager = SearchManager.getSearchManager(session);
SearchObject search = manager.newSearch(searchTarget, pom);
return search.toXML(false);
}

When I execute the saveData() method on the ListGrid:

mySearches.addData({SearchTarget: node.SearchType}, "setSearch(data)");

where node.SearchType is bound to a valid value, I get the following error in the server log:

Please advise me as to what I might be doing wrong.

Remove these settings:

dataFormat="xml"
recordXPath="//SearchObject"

They don't apply to DMI.
