Hi Andres

I’ve checked in version 4.0.1 and I have the same issue. When I checked the help it says:

“About Trees Created as Shared Components

Previous releases of Oracle Application Express supported the creation of trees as Shared Components. Although existing trees are still supported, Oracle Application Express no longer supports the creation of trees as Chared Components.

Oracle Application Express now supports the generation of a jsTree tree region. jsTree is a javascript based, cross browser tree component. It is packaged as a jQuery plugin.”

I’m not sure what version these were removed in, however, looking at version 4.1 it appears trees are back! So you will need to upgrade to APEX 4.1 if you want to create a new tree.

Hello Sarah,
Thank you very much, your postings are very interesting. I have a problem following your instructions. I can’t create the Tree from the Shared Components pages. In the “Navigation” Region it only shows Tabs, Lists, Breadcrumbs and Navigation Bar Entries.
Do you have an idea why this is happening?

Best regards,
Andres

Hi Nilesh

Page 0 isn’t a page that is viewed through the application front-end, instead everything that’s on page 0 is displayed on every page in the application. So if you’re trying to view page 0 you’re not likely to see anything.

If you’ve created the region and P0_TREE_ROOT on page 0 as described in the post, then these should be displayed on any other page in your application.

Hope this helps.
