[P2][Sourcing][Regression][Platform Table]: After scrolling and applying filter , the rows rendered are not correct

[I543348]

Is this a bug, enhancement, or feature request?

Bug

Describe your proposal.

When table with pageScrolling is enabled with pageSize say 20 or 30.
On scrolling to 2nd page , the data loads with next set of rows.
Now at this state, filtered rows are not getting displayed in the table

Observation: datasource model is getting updated correctly with filtered rows, but the view is not updated.
Expectation: The table has to render correct rows based on filter no matter on which page we are.

Can you handle that on the application side

No

Which versions of Angular and Fundamental Library for Angular are affected? Please, specify the exact version. (If this is a feature request, use current version.)

Angular: 15
Core /platform: 0.43.17

If this is a bug, please provide steps for reproducing it; the exact components you are using;

1. Use the stackblitz
2. The table example has 60 rows with pageSize= 30, now scroll to get 2nd page data (next 30 records)
3. Now click on button "Filter Results"
4. Observe that rows are not filtered based on data source

Pls note this issue works fine in 0.41.1-rc.7 but not working in 0.43.17 , hence regression

I think view is not getting updated based on dataSource of the table in this case.
The filtered results works fine when user is not moving to other pages other than 1st page,

The datasource swapping should not cause this issue, but it causes, I agree. But also, this is not how rows should be filtered. You should set filters on provider and that's how it should update the items which are rendered, not entirely swapping out the full data source

Verified on NGX stackblitz using 0.43.18 and the issue seems to be fixed.
Thanks.

Hi @N1XUS , This issue #11002 is again replicable after fix for #11057, pls find the stackblitz link

Here pls follow below steps to reproduce the issue

Use above stackbliz
Click on filter results button
