Loading icon not visible
I am using AsyncTree to load the children of a node on demand. However, the "async load image" is not visible. What should I do to make this image visible when the child nodes are being loaded.
Similarly, when the TreeGrid is loading the data, I am not seeing the "Loading" image. I set the tree.setLoadMask(true).
I must be missing something very basic. Can any of the experienced ExtGWT members help?
