TreeGrid fireEvent UmbrellaException

I'm getting this exception after I'm adding a number of child nodes for a parent node. I've seen this to happen here

You should post your code causing this exception.

[Colin Alworth]

That doesn't help - some of the samples are built like that, but don't produce this error. Actual running code will allow us to either find the issue, or point you in the right direction to fix your code.

Hi Colin,

I already found the reason for that exception. I constructed my tree node class in a not proper way.

Now those errors are gone, but I'm thinking why in a treeGrid I can't sort ascendent or descendent my tree grid columns. I also see that in DP5 examples sort operation is doing nothing also.

Also RowNumberer is not working well for TreeGrids.

Tnx !

Could you explain how you fixed it? Looks like I have a quite similar problem...
