Hi,
We're using SmartGWT 4.1 Power Edition (v9.1p_2014-06-04).
I'm facing a problem regarding DataSources with cacheAllData set to true and ListGridField using such data sources as optionDataSource.
Scenario:
- 2 users connected to the application.
- 1st one performs an update operation on cached data source.
- 2nd user client is notified of operation (with our own push system), which triggers call to DataSource.invalidateCache()
- 2nd user refreshes a grid with a field having this DS set as optionDataSource
=> Change isn't taken into account.
This problem seems to affect only ListGridFields: performing a refresh on a ListGrid that uses this DS, or displaying a SelectItem with this same DS triggers the following request:
When DS is used only as optionDataSource on a ListGridField, refreshing the parent ListGrid doesn't trigger cache reload.
Issue can be reproduced with all operations (add/update/remove).
DataSource definition:
Client code that handles data changes notifications:
Did I miss something in client-side cache configuration? Or is there a special setup for ListGridField?
Thanks in advance for your help
