gb.web.gui application jam druing the execution

Description
-----------

Hello,

A bug occured during the execution of one of my project - Web Application (gb.web.gui).

At certain moment, when a Message Box should be displayed into the Web Page, the 3 little points appear indiquing a delay, but the Message box never appears and the 3 little points still running in the page.
To bypass this step, I had to refresh the Page by the Refresh button (F5) of the Browser, and after that the correct Message.Box is displayed, as it should be.

In my application there is a WebTable connected to a Result object (~1360 rows) (connected to a Memory Sqlite3 DB).
When the Webtable display the first rows on screen 1 −> 100, it works as expected, no 3 little points appear on screen, but when the last rows of the WebTable are displayed on screen, most of the action by the user in the Web Application is impacted by a certain latency and raise the 3 little points.

On my understanding, it seems that if a WebTable display last rows of a Result, any changements into the Web Page for a refresh of those rows, cause a latency, and maybe a bug.

I attach the screenshot showing the error in the Javascript library (Web Page side).

I hope it will be enough information because if you ask for a little projet to reproduce the issue, it will be really complicate... (25000 lines of codes...)

Than you

Olivier
