I'm working with a treeview control and the expand and collapse buttons (+/-) seem to dissapear every now and then.
On the development side this problem is rare whereas on staging and production it happens once or twice a day. The only solution I've found is to "refetch" the page from the server by holding "shift" + clicking refresh. It seems to only be occuring on the the tree controls. I do use on-demand node population based on expand and collapse.
Attached is a screenshot of the problem. Let me know if you need more information from me.
Thanks in advance!
