Fwd: [flexcoders] Re: AdvancedDataGrid preserve openItems after data update
Hi, I did not fully understand how did how built objects or matched items. Could you be more explicit or could you show part of your code ?

Fwd: [flexcoders] Re: AdvancedDataGrid preserve openItems after data update
OK here's what i did to keep my nodes open.
un my update function i call preventDefault() to stop the expected operations.
then i manually build using updated data my object instances
then search the original objects till i find my matching object
overwrite the orginial object with the new instance
then run a refresh() on the dataprovider.
This appears to be working for me and it is having the expected
results.so far :)

Can you post a sample in which the issues occurs?

[flexcoders] Re: AdvancedDataGrid preserve openItems after data update
Scott and Jonese:
I am currently trying to deal with the same issue. I was
actually ALMOST there, but I think I have discovered a bug in Flex.
So the problem: Keeping the AdvancedDataGrid nodes that were already
expanded, open after a filter and refresh (specifically
a 'GroupCollection' refresh).
First, I got a nice array of objects containing the 'nodes' for the
grid nodes that were opened, "adg.dataProvider.openNodes"
Next, I did the filter and gc.refresh().
The final step was to iterate through all the nodes, find out which
ones had the same "GroupLabel," and expand them
using "adg.dataProvider.openNode(node:Object)".
This is where I ran into problems. When I tried to re-open a node
using openNode, the node would expand, but the nodes below it would
not be in the right tree level (it seems as if they were stepping
down in level one by one, even though they were supposed to be all on
the same level below it). Now here is a real kicker! If I go to
click on anything in the grid after that, the display automatically
corrects itself! So odd.
If anyone has seen the same thing, or know what I'm even talking
about please let me know. Thanks!
