getItemsREST Error: Internal Field Name

[MikeS]

SPJS Charts Timeline (and other charts) throws an error related to the Field Internal Name assigned by SharePoint 2013 for a date field. SP assigns a Field Internal Name for Date Fields differently depending on the field name. See Figure 1. When date fields begin with a number the Field Internal Name generated by SP does NOT match the entered Display Name. These Field Names then throw an error in SPJS Charts. See Figure 2.

However DFFS has no problem working with these internally generated fields (see Figure 3). Why is SPJS throwing these errors? I cannot redo the entire list with date fields that contain only alpha characters. Would using a straight JavaScript solution in SPJS Charts provide a way forward? What would that look like?

Very happy with DFFS and want to use SPJS Charts if this issue can be resolved.

SPJS Charts v. 7.0.0.5

Thanks for you help,
Mike

Hi,
This is a problem with field names starting with “_”. Is this error occurring when using the fields in a filter?

If it’s in a filter, prefix the field name with “OData_”, but if it’s in the Datatable fields, I need to fix it in code.

The fields that throw the errors are used in the Datatable fields (see Fig. 4). A code fix would be very appreciated. I’ll be happy to test it for you.

v7.0.0.8 of SPJS Charts released Sept. 20 fixed the error from date fields beginning with an underscore. Nice job Alexander. Thank you.
