Wt

I having problems with the "lazy loading" of items in a WTreeView.
When the model is significantly changed (many items removed / added) the loading ceases to work and items stop. With CSS, this causes the "Loading" graphic to display and never close.

Replacing WTreeView with WTableView runs the same code ok.

A minimal sample is attached:

• When the page initially loads the items scroll ok.
• Now click the button at the top forcing the model to be rebuilt (all items removed and re-added).
• The scrolling now stops at around item 150.

Am I doing something wrong here, or is it a bug?

ps. It looks similar to this from 11 years ago, but now cases seem to have reversed (WTableView works, WTreeView doesn't): https://redmine.webtoolkit.eu/boards/2/topics/3733?r=3968
