Hi Jakov
We can't replicate the case. After calling
table.setClearOnRemove(true);
page.removeTable(id);/
the table should disappear and trailing updates should be ignored.
If we understand well, the problem happens to you when you call those lines while the previous table is still loading. We also tried simulating this case, but we didn't notice any update from the previous table mixed with updates from the second one.
We need more details on your case.
Are you using Web Client Library version 4.3?
If you, for testing, only issue
table.setClearOnRemove(true);
page.removeTable(id);/
without adding the new table, can you see the table complete loading?
Does the table loading take 30 seconds because of bandwidth restrictions? Or because of CPU overload on the client? Or because of slow data generation by the Data Adapter?
Can you exclude any issue in the Data Adapter, perhaps mixing updates for different items?

After further tests we could replicate the case
and recongnize it as a Web Client Library bug.
Trailing updates pertaining to the previous association for the screen table are not filtered out correctly. This may affect any kind of screen table and subscription mode.
We'll make a patch available as soon as possible.

Hello all,
a patch for the problem described in this thread is available.
If you are using the Lightstreamer Web Client v.4.3 build 1346 and think you are in the situation described below, you may want to apply the provided patch:
On the Master Push-Page, if you call addTable() more times while using the same "id" parameter, there exist cases where the last updates pertaining to the previous subscription life are delivered as part of the new life. An example of this is if you define a screen table through your HTML cells, bind it to a Lightstreamer table, then remove the Lightstreamer table and add a new one in order to chnage the group name. If this is done in rapid sequence, the latest updates pertaining to the old group could be displayed after the new group has been subscribed to.
If you find yourself in this kind of scenario and you are using Lightstreamer Web Client v.4.3 build 1346 (previous version are not affected by this issue), please contact support@lightstreamer.com to get the patch.
