TreeGrid

[Victor Costa Santiago]

Hello good afternoon!
Need help from you guys regarding a question / problem ...
I have an XML like this


ABC 
1 
0 
WAS 


DEF 
2 
1 
Method 


GHI 
3 
2 
Object 


JLM 
4 
3 
Object 


NOP 
5 
4 
Parameter 


QRS 
6 
4 
Parameter 


Xml This is populating a data source to a treegrid. What I needed was the
following:
1 - the tree is the look of checkbox. This item I've ever done as the
showcase but wanted to see if there's only the leaves (leafs) of parameters
have the look of checkbox.
2 - need to have the same level of nodes / leaves to be checked the other
one is how deslecionado a radiobutton. This parameter in the case of the
leaves that are there and can occur over an object there that only allow one
selection.
3 - I used the feature selection cascade but only wanted to work as follows
when selecting a level below the root of this that would be just above that
were selected in casacata and not those who are below the hierarchy, not to
disrupt the Item 2.

Is that possible? I am two days ago and found no examples or methods on the
internet that can help me.

Thanks in advance!

Ext-GWT TreeGrid indirectly calls a GWT-RPC callback? Why?

[Pandaman]

I am using GWT-RPC to populate Ext-GWT TreeGrids with data from a
server. I am using 4 callbacks to populate 6 TreeGrids. As the
callback onSuccess function modifies the TreeGrid by inserting rows,
the TreeGridView needs to render the rows. The callback class is
called MainPnlSummaryTablesAsyncCallback.

For some reason, when it needs to determine the TreeGridView's
scroller's offsetHeight via JSNI, onSuccess or onFailure is called on
another instance of the callback in the stack trace. A copy of the
stack trace I encountered is below.

Isn't this really weird? Why is this happening?

FYI I am using Ext-GWT 2.0.1 and GWT 1.7.0 and I am using hosted mode
browser to debug this, although I am pretty sure that this is an issue
for web mode.
