Not sure I understand this ?

Locate in TDataset is empty. It must be implemented in descendents. 
For Pas2JS this is done in JSONDataset.

As far as I know, TWebClientDataset cannot inherit from TDataSet, it would
be empty ?

In each case, TMS Web core does not yet have a "locate" implementation, their
latest release predates the implementation of "locate".

Can you please try to reproduce the issue without using TMS Web core, with
plain pas2js ?
