expandAll/collapseAll does not work

[nenadmaricic]

I changed Demo/simple.component to support expandAll/collapseAll. But when treeModel.expandAll/collapseAll is called nothing happens. Seems that node statuses are correct because when node content (not expander) is clicked, it expands/collapses. Any idea how to solve this ?

Hi, some code updates are forgotten to be pushed to github. Now it should be the latest.

I also add a throttle logic for viewport update in one event loop.

BTW, it could be performance headache if you expand large scale tree. But it will work now.

I have a similar issue. Clicking on the expander does nothing, then if I click the label of the expander, the section is expanded. It looks like a ChangeDetectionStrategy.OnPush issue.

Ok so I found a workaround for the issue by adding a (expand) event listener:

onExpand() {
        // workaround for the category not expanding
        setTimeout(() => {});
    }

@lucipacurar it would be easier to solve your problem if you could provide a reproducible example
