I am using tree component as dropdown factory for combo box. When i open dropdown, it doesn't have vertical scrollbar and all the root nodes are getting displayed correctly(in closed mode). Now if i try to open any node, i am getting vertical scrollbar as the child nodes are more. Now the problem is if scroll down, some of the nodes(labels) are not getting displayed but i am able to see the icon. If i keep on scrolling bottom to top and top to bottom, some of the nodes are showing labels and some are not(It is inconsistant).
I have not used any custom item renderer for tree control. I used my custom dataDescriptor which i have implemented from ITreeDataDescriptor. Also I tried extending DefalutDataDescriptor, but no luck.
