This is a big deal for me, because when I have to close the project just so I can edit a table that I had a filter applied to (after removing the filter) and then reopen the project again.

However I think there is a whole question here of why editing a filtered table is blocked. In my maps which are used to show generations of historical data, there can be overlapping features that you want to hide to be able to draw in different generation ones. At the moment I have to create them in a separate table then paste them. Now imagine that I need to edit, then having to make another copy of the data to make changes to it, and then paste back.

Here is a need for a paradigm shift for working with a filtered table. When a filter is created on a layer, the GUI should create a temporary copy of the table, apply the filter to it and use that copy for the displaying of data. But allowing the user to edit the real table. Or something like that.

• Put a filter onto a table
• Put the table into edit mode
• Add a new feature or change an existing one
• Save the layer
• Take the layer out of edit mode
• Remove the filter
  without apparently any repercussions.

The layer type is a shapefile.

1. What is the technical reason for the limitation being desirable
2. Is there a technical reason for the change being necessary after 2.14 but not an issue in 2.14
3. Is there a different file based layer type that does not require these limitations.

TIA

Hi,
the filter I applied wasn in Properties --> query builder (not in attribute table) because I need to see only filtered records on the canvas;
the filter applied on attribute table works fine but don't filter the shapefile in the canvas then the issues is a little bit different...

In view of the additional restrictions being applied in 2.18 and later maybe there are some questions that could be answered in another forum? Maybe they already have.

I'm not sure I understand the above.
The filter in vector properties > query builder effectively will show you only filter records and features. The second part is not clear at all. I'm also not sure if the comment fits the issue described in this ticket.

The second part is referred only to the steps described in the first post by
Patrick Dunford, because It applied a filter onto attribute table, not on layers proprierties...

I still don't understand how this is related to the original description of this issue.

I think I do. You said "This ticket can probably be closed as now the behavior is consistent", but it would be very useful for the behavior to be consistent the other way, with filtered layers always editable.

Because now it is not possible to have a filtered layer on the canvas and be able to edit its attributes. This is also what I'm looking for.

Edit: found #13292 for this.

In fact any change in snap tolerance setting don't solve the issues

this ticket isn't related at all to snapping.
