Getting/Reading values in callback

[yathish.venkatesh]

Isomorphic,

I am invoking a method using a data source and trying to get the data from this DMI through callback as shown Below.

        DataSource dataSource = DataSource.get("dateRange");
        DSRequest dataRequest = new DSRequest();
        dataSource.fetchData(createCriteria(), new DSCallback() {
            @Override
            public void execute(DSResponse dsResponse, Object o, DSRequest dsRequest) {
                Record r = dsResponse.getData()[0];
                String userName= r.getAttributeAsString("userName");
                String host = r.getAttributeAsString("host");
            }
        }, dataRequest);

In my DMI, i am actually setting the data by creating an object of class UserInfo as shown below.

UserInfo objUserInfo = new UserInfo();
objUserInfo.setUserName("ABC");
dsResponse.setData(objUserInfo);
return dsResponse;

public class UserInfo {
    private String userName;
    private String host;
 public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }
 public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }
}

I tried all getAttribute functions to retrieve user names, but none of them are giving me the correct user name and host.

Let me know how can i achieve this.

Take a look at the RPC tab in the Developer Console. If those getAttribute() calls aren't working it probably means you are returning blank data.

I had a look at RPC tab. It says the status is successful.

dsResponse.setData(userInfo); Here i have 2 properties set in userInfo object.

How can i check getAttribute() calls are working fine or not in RPC tab?

Post the actual contents of the RPC tab here.

RPC Request tab

{
    "actionURL":"http://127.0.0.1:8888/MarketIntelligence/sc/IDACall", 
    "showPrompt":false, 
    "transport":"xmlHttpRequest", 
    "promptStyle":"cursor", 
    "bypassCache":true, 
    "data":{
        "criteria":{
            "USERNAME":"sg206965", 
            "PASSWORD":"Sabre123"
        }, 
        "operationConfig":{
            "dataSource":"dateRange", 
            "repo":null, 
            "operationType":"fetch"
        }, 
        "appID":"builtinApplication", 
        "operation":"dateRange_fetch", 
        "oldValues":{
            "USERNAME":"sg206965", 
            "PASSWORD":"Sabre123"
        }
    }
}

Response-Raw tab

[
    {
        queueStatus:0, 
        isDSResponse:true, 
        invalidateCache:false, 
        status:0, 
        data:{
        }
    }
]

Do i need to set cache true?

As suspected, you are not sending data back. Show your DataSource definition - have you actually declared the fields you are trying to send back? See also DataSource.dropExtraFields.

[yathish.venkatesh]

<DataSource ID="dateRange" table="CLIENT_VALID_DATES" serverType="sql" dbName="Oracle" showPrompt="false" qualifyColumnNames="false">
    <field name="userName" type="text" required="false" title="userName"/>
    <field name="host" type="text" required="false" title="host"/>
    <serverObject lookupStyle="new" className="com.sabre.apd.mi.smartgwt.server.SsoUser"/>
</DataSource>

This is my DataSource. Let me know what is wrong!!

The only problem with any of the code shown here is that you should technically call setData() with your UserInfo object contained in a single-element List. If that's not the issue, work toward a standalone test case we can run to see the problem.

[yathish.venkatesh]

Did you mean the object of UserInfo should have only one data member as a list/Map??

As of now, i have two data member(userName and host)
