[Users] GeoExt.grid.featureSelectionModel problem

[Christian Mayer]

Hi Brad,

What I detected is the fact that you determine the size of your records with

var recno = grid.store.data.items.length; 


you should use

var recno = grid.getStore().getCount();


I am not sure this has any effect but maybe you could try this.

But your information "/I get the feeling its just setting to the last
record before it actually gets included in the grid?/" maybe is the
right approach. You can ensure that the feature has been added to the
store by binding to the "add-event" of the store (see [1]) and try to
perform your code that focus the last row within the listener function.

Best regards,
Christian
