Celltree Refresh question
If I add a new node to a tree which has been previously rendered via Celltree, how do I add the node to the tree model and render the modified tree without (hopefully) reloading and redrawing the entire tree? Is an example of this process documented anywhere? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Problems selecting a Cell in a CellTree
John, thanks for the idea, but the goal is to identify a particular
cell to permit the change of a whole set of parameters when a
particular cell is selected, not just the text in the cell. I don't
want to show all the parameters in the tree, just the label for them.
The goal would be to pop a dialog box once the cell is selected to
allow the user to enter all the additional information. The tree
construct is useful because it shows the relationships between the
various nodes.

Have you tried EditTextCell? It shows readonly text, but turns into a Text
Box when you click on it. Sounds like what you want.

Re: Working in development mode in GWT with php
I have ths exact problem with another JSON application using GWT
2.0.
It works fine when compiled but the exact same code does not work in
hosted mode.
I am using SmartGWT, but do not think that is the problem...
