Hello,

using: Isomorphic SmartClient Framework (v8.2p_2012-07-30/PowerEdition Deployment 2012-07-30)

I have a listgrid in my system, and it has the fetch operation: joinEverythingExceptPresence (see below)

When I do the following:
1. Set a filter in one of the headings
2. Update any field in the filtered record (inline)
Then ==> The stacktrace on bottom of this page shows. This doesnt happen in all grids in my system (i have multiple 'similar' setup grids).

The data is correctly saved to the server, but continuing editing other rows, or changing the filter gives all kinds of strange things. Effectively, refreshing the page is the only solution for the end user.

I tried without the cacheSyncOperation, to no avail (since the stacktrace appears to be related to cache updating).

I know this is not a standalone test case (pretty hard to create one at the moment), but could you already say something about this ? Could you give any hints to what to do next to pinpoint this problem further?

Oh yes, it happens both in Dev mode, as well in production mode on all browsers.

Update: it seems that a filter is not even necessary to trigger the problem.

I'm currently stripping the grid from fields etc. in a test version to see if i can isolate the problem.

I found it.

There was some external cellSavedHandler that called invalidateCache(); on the same datasource as the grid.

This caused these caching conflicts i think. Will look for solution on the matter, since it seems the invalidateCache was abused to refresh another widget.

hi Sytematic,

I am using Smart-gwt version 2.4 and smart-gwt 2.5. I am facing the same error. Can you tell me the solution over this problem?

Hello. As a way of debugging this, I would suggest, make sure you out-comment/remove all the invalidateCache() calls that act on that datasource through your whole application.

It's hard to say 'this is wrong' with your information, but invalidateCache() can break things if you misuse it (as I did).

Hope that helps.
