DataSource not sending start/endrow in 13.1

[mathias]

Hey just upgraded to 13.1 13.1-p20250110.

Summary:
We have a Timeline calendar that has problems problems loading data after we've upgraded.

It seems that in 13.0, the request contains start row and end row, but not in 13.1.
This results in the DSRequest included with the DMI call has a startrow of 0, and an endrow of -1.

The DSRequests in the network debug looks basically the same except for that in 13.0 it has the

<startRow xsi:type="xsd:long">0</startRow><endRow xsi:type="xsd:long">4000</endRow>

and it's missing after we upgraded to 13.1

The 4000 comes from setting

setDataPageSize(4000);

on the TimeLine.


Is this a known thing? Am i doing something wrong? Happy to provide more details if you need it.

Would be great with some feedback asap, it's keeping us from upgrading.

Cheers

In 13.1, we added fetching based on visible date-ranges and, as part of that, changed the default value of Calendar.dataFetchMode to "basic", so that all events in the accessible range are client-side.

We'll revisit whether this is necessary in Timelines but, in the meantime, setting dataFetchMode to "paged" on your Timeline should revert to the behavior you expect.

OK, thanks for quick response.
