CellTree: Changing the default "no data" message for empty nodes

[aarnott]

Is there a way with the CellTree to change the default "no data"
message when a tree node is empty?

Maybe I'm taking the wrong approach, but I am using an RPC to load the
children of a particular node once it is opened and when the loading
is happening, the node shows the "no data" message. I'd prefer to
change the message to something like "Loading..." :-). Otherwise, I
can always add a child cell that has the loading message and then
remove it when the real children are loaded, but that seems clunky.

It appears that there is not.

 

Pretty disappointing, I was hoping to use CellTree in my new project... thought in my case I do not want the message at all, which is also not possible.

Which is actually fixed (will ship in 2.5.0-rc2)

Hi Thomas

 I am using 2.5.1 GWT version. I would like to modify the Empty message in cell tree. If it has been fixed can you please let me know what the fix and how do I modify the hard-coded message. Any help will be greatly appreciated.

The issue links to the change: https://code.google.com/p/google-web-toolkit/source/detail?r=11095

There's a CellTree.CellTreeMessages interface with the constants. It's standard GWT I18N so you can provide translations the usual ways. You can also extend (or even implement) the interface and pass an instance to the CellTree constructor.
