Databound datasource extension: issue with data property

Hi all,

I currently try to develop a datasource extension that consumes another datasource and manipulates it. So I built a dataBuffer extension according to the developers guide, added a property of Type ResultCellSet and a corresponding getter/setter. Now I would expect a Data-Runtime-JSON being passed to this getter/setter after selecting data.

Defenition of property:

<property

     id="inputdata"
     type="ResultCellSet"
     title="Input Data"
     group="DataBinding">
    <option name="includeFormattedData"  value="true"/>
    <option name="includeMetadata"  value="false"/>
    <option name="fillMetadataProperty"  value="true"/>
    <option name="maxCells"  value="500"/>
</property>

The issue is that with the above configuration my inputdata getter/setter will never be called and (with assigned datasource) a warning shows up in the error log saying:

The component "DS_3" does not have a data source. In this case, data-bound properties cannot use the "fillMetadataProperty" option.

Now, when I change the properties configuration so that includeMetadata ist true and fillMetadataProperty is false, the inputdata getter/setter gets called but only with a selection string instead of the expected Data-Runtime-JSON.

Example of selection string being passed:

{"(MEASURES_DIMENSION)":"0D_NWI_NSAL","0D_NWI_RCOD":"80503"}

Does anyone experienced this behavior as well? Could this be a bug in the sdk?

Kind Regards

Tim

More Information:

I searched the scn and did not found anything about an issue like this.

Then I imported the scaling datasource extension from the sdk examples, logged the input of data getter/setter and got a selection string, too, instead of a Data-Runtime-JSON, resulting in a malfunction of the extension.

Moreover I tried multiple combinations of different options of the property, different datasources and Design Studio versions 1.5 and 1.6.

I never got an Data-Runtime-JSON.
