Datatable with subview problem

Hi, I have a datatable with 2 subview.
It works fine if I open a branch and then close it before opening an other branch, but if I open a branch and then I open another branch without closing first the open branch, there is a strange behavior where all the rows of the first open branch disappear.

Here is a snippet with my code:

Here is another snippet with only 1 subview, but the problem stay the same:

To see the problem just click on the first row and then click on the second row without closing the first one.

I guess I am doing something wrong on the subview binding…
Can you help me?

Thank you.

I found the problem, you can’t give an ID to the subview datatable. If you do it, when you open the second subview, this will replace the previous subview.
