HttpProxyServlet has problems with complicated criteria from RestDatasourceRequest

[Blama]

Hi Isomorphic,

using v10.1p_2016-11-25 I hit this exception when sending a request from a SelectItem via RestDataSource:

Request from Developer Console Watch tab:

{
    dataSource:"T_LEADTEMPERATURE",
    operationType:"fetch",
    componentId:"isc_PickListMenu_2",
    data:{
        operator:"and",
        criteria:[
            {
                fieldName:"STARTDATE",
                operator:"lessOrEqual",
                value:"2016-12-01T11:06:25.737"
            },
            {
                operator:"or",
                criteria:[
                    {
                        fieldName:"ENDDATE",
                        operator:"greaterOrEqual",

                    {

            }

Debugging shows that before the exception value in line 613 is:

[{fieldName=STARTDATE, operator=lessOrEqual, value=Thu Dec 01 12:06:25 CET 2016}, {operator=or, criteria=[{fieldName=ENDDATE, operator=greaterOrEqual, value=Thu Dec 01 12:06:25 CET 2016}, {fieldName=ENDDATE, operator=isNull}]}]

You confirmed using another approach, so we did not rush the fix. FYI, this is fixed now across all latest versions.

Hi Isomorphic,

thank you. No, it was not important for me. Not using the RESTHandler so far.

Best regards
