about omitNullMapValuesInResponse

[xml-leo]

SmartClient Version 8.0

in DMI#fetch
just return dsResponse.data = List<Map<String, Object>>

that map contain key/value pair with null values

I just try to set omitNullMapValuesInResponse=true, or omitNullMapValuesInResponse=false, but that entry with null value in that map can not pass to client

I would like the response showing as below, but how can I do it ?


//isc_RPCResponseStart-->[
{
queueStatus:0,
isDSResponse:true,
invalidateCache:false,
status:0,
data:[
{
status:"Y",
port:null, <-----this entry can NOT show ????

Hello Isomorphic, I was just trying the omitNullMapValuesInResponse attribute, but id doesn't seem to work.

Please try this test case in the #fetchOperationFS sample:

isc.ListGrid.create({
    ID:"dsListGrid", 
    width: "100%",
    height: "100%",
    dataSource: "supplyItem" 
}).fetchData(null, null, {omitNullMapValuesInResponse: true});

the response doesn't contain null values.

[Isomorphic]

Omitting (which means leaving them out) null values is exactly what your code is saying to do.

[claudiobosticco]

oh, sorry for being dumb :-(

I meant to post a test case with omitNullMapValuesInResponse:false, as:

isc.ListGrid.create({
    ID:"dsListGrid",
    width: "100%",
    height: "100%",
    dataSource: "supplyItem"
}).fetchData(null, null, {omitNullMapValuesInResponse: false});

where the response still doesn't contain null values.

If this is the supplyItem from the Showcase, the data is not provided as Maps. It's from SQL, and we don't retrieve nulls from SQL.

[claudiobosticco]

thanks, I didn't think it wasn't a valid setting for SQLDataSources.

[Isomorphic]

It's a valid setting for any DataSource. However, for SQLDataSources, the Maps that are retrieved from SQL already lack nulls. If you had a custom response with your own Maps and they had nulls, they would be preserved.
