This issue has to be fixed in two steps

1. Fix NumberFormatter - Done - I just pushed fix and it should be available with build 28
2. Fix labelFunction - I will try to get back to that on tomorrow or on Wednesday

@aharui I have implemented labelFunction handling in item renderer in following way, but it doesn't work and I think it may be a compiler issue.

1. I have created DataGridColumnICollectionViewModel for AdvancedDataGridColumnList which holds columnIndex
2. AdvancedDataGridView sets columnIndex
3. DataItemRendererFactoryForICollectionViewAdvancedDataGridData sets columnIndex in AdvancedDataGridListData using created model
4. AdvancedDataGridListData provides all data in item renderer to call labelFunction

I'm assigning my labelFunction like that:
<mx:AdvancedDataGridColumn dataField="ci_Code" headerText="Code" width=".40" labelFunction="fn_FormatGrid" />

For some reason it's not being called from item renderer. It looks like some anonymous function without any params in debugger. I'm attaching example with build based on my branch.

@alinakazi , @pashminakazi I just pushed changes which should fix this issue. Note that there were also fixes on compiler sight, so make sure that you have also fresh version of that one.

@pashminakazi any update on this ?

Example : https://paste.apache.org/pdbn4

@pashminakazi but your example itself is invalid - do you see that ? You are providing data source with strings:
new ArrayCollection(["24236482.324234", "23424.435","42344.23423"]);

and later you are trying to reach item with property item.ci_Code <- This property doesn't exists at all. Remove property item.ci_Code and it will work.
fmtAmount.format(item);

Or provide proper data source:

new ArrayCollection([{ci_Code : "24236482.324234"}, {ci_Code :"23424.435"},{ci_Code :"42344.23423"}]);

To me issue is resolved. Function is launching properly and formatter was also fixed.

Issue has been resolved Thanks
