source.remote.hostFilter

Raised by

The grid (core)

Since

1.16.0

What happened

A hostFilter is application logic the grid cannot serialise, so it cannot be sent to a server. Applying it locally would filter only the rows already fetched, which makes the count, the totals and the scroll length all describe a different set from the one on screen - so it is not applied at all.

The fix

Express the narrowing as a declarative filter condition the source can send, or pass whatever the server needs through config.context.
