 This is the code :-

 RAMSubCategory subCat = subCategory.createSubCategory(assetObj.getName());

session.put(categorySchema, new RAMStatusMonitor());

assetObj.categorize(subCat);

session.put(assetObj, new RAMStatusMonitor());

User Action - User creates a subcategory asset and wants that subcategory asset to get displayed in the Visual browse window.

Please help.

Thanks,
