subcategory not showing up in the catalog schema hierarchy

Didn't you just append another question about not being able to create a subcategory?

So it this question no longer of use?

Actually, the subcategory is getting created but the error occurs in the refreshing the category schema.

getRAMSession().put(categorySchema, new RAMStatusMonitor());
But, I noticed that the sub-directory is created but does not show up in the catalog schema hierarchy, however if I go and create an asset under that sub-category, then the sub-category shows up.

But, this is not desirable. I need the sub-category to be displayed on the catalog hierarchy when it is created. I should be browse to that sub-category.

Hope that clarifies the doubt.
