Bug: GeoExt.data.FeatureStore in Synchronizing FeatoreStore with Vector Layer

[Shadin]

There is something wrong in GeoExt.data.FeatureStore ,

I followed this example to load WFS vector features into a grid.
http://geoext.github.com/geoext2/examples/grid/feature-grid.html

It works once, then fails many times, then suddenly works once again ... and so on.

Hi @Shadin , sorry for being so late.

Could you provide some details about what is going wrong?

A complete failing example including the HTML would be super helpful.

Thanks.

Hi Mark, hi Shadin,

I've just changed the vecLayer to get data from a WFS. Using a BBOX strategy works great, but soon as the user starts editing, the features disappears from the map (but not from the grid). Zoom out to see the features again, but there is something wrong with the synchronization.
I'm sending the link to a working example where the synchronization apparently does not work.

Comments are welcome.
Thanks,
Jorge

Hi,

The synchronization fails when editing, even with the GeoJSON layer.
To replicate the problem, just add an insert control and soon as the user enter a new feature, the synchronization is lost.

Jorge
