WoWInterface - [TBC Beta] Expand Interface Category

Found solution after posting. Needed to assign the hidden variable for the subpanels before calling InterfaceAddOnsList_Update.

I used to be able to do this on an older version of the game, but i'm running into issues on the TBC beta client.

I'm trying to collapse/expand a category through code.

Here is example code to create a category with one subcategory.

Code:

panel = CreateFrame("Frame")

panel.name = "Test Category"

InterfaceOptions_AddCategory(panel)



local subpanel = CreateFrame("Frame")

subpanel.name = "Sub Category"

subpanel.parent = panel.name

InterfaceOptions_AddCategory(subpanel)

Here is my code for trying to expand the category.

Code:

panel.collapsed = false

InterfaceAddOnsList_Update();

The "expand/collapse" button updates, but the subcategory visibility is not actually being updated here.

I also tried with

Code:

InterfaceCategoryList_Update();

Any ideas on how I can achieve this?
