TreeGrid Store question
Currently working on a proof of concept with Ext-GWT. Current usability scenario involves using the TreeGrid to manage add/edit/delete (using a context menu) of a Hierarchy model using the TreeGrid control. The TreeGrid uses lazy loading to load the children using a loader.
We ran into a couple of issues with the above functionality with the TreeGrid.
1. Using a row editor on the tree grid, we could not calculate the right row to show the edit part -
the above method does not work when one the other parents above in the TreeGrid is expanded. The not so ideal workaround is to use a pop-up form.
2. How does the method treeGrid.getTreeStore().getModifiedRecords() handle records(model) that have been removed ? Is there anyway to ask the record if it was an add/update/delete ?
If any of my questions are unclear, please feel free to ask for more information.

Did you ever get anything figured out with question 1. I am currently having the same issue when calculating the index. Any input would be appreciated.
