I have a problem that's bugging me.

I have a grid and when i dblclick on a item I want to open a window to edit that item. Pretty standard stuff. The problem is, i want to be sure the record is up to date, because other people using the program may have changed it or even deleted it.

I could reload the store, but i only want one specific record to be checked... So i figured i would just go get the data, build another record and replace the existing one in the store but i really want to know the best way to do this

Bear in mind RESTful proxy is not an option for me, even though i don't know if the update operation works in this case ( server -> client).

EDIT: this may help somebody: all i did was copy the data and raw objects from the new record to the old one and then "commit" the changes. worked for me.

Thank you.

ExtJS 4.1

I had a similar problem and as an experiment tried

sStore.load({ id: mskey, addRecords: true });

where mskey is a uuid of a currently loaded record.

I did not remove the existing record first (as an experiment) and it updated the existing record that had the same id with the new data from the server (via the model --> REST proxy). Perfect!

I know you said you are not using a REST proxy, but this might help others who found this post searching for search terms like your topic name (which is how I got here!)

So, it looks like 'addRecords' means add or update.
