Hi,
My vCO plugin has impelemented inventory, it works perfectly in vCO client, but in web operator, whe I try to expand the tree structure to the second level, exception is thrown (it has no problem expanding to the first level), the log is pasted below, seems like a problem for converting the objects, can someone please let me know how can an inventory works well in vCO client, but malfunctions in web operator, where is the difference?Is there extra work that needs to be done to make it work in web operator? Thanks in advance.
