Test case is available on VDI.
Go to Accounts Recieveable from Select in Menu
Go to Sales Commission Scheme Setup from Setups in Menu
File : com/dbz/modules/AR/dbzSalesCommissionScheme.mxml

Click on New Button then Plus (+) button,Popup will be opened and then click Plus (+) Buttonn and then attachment icon,attach any files

Whole row should be highlighted when we select a row.File Name is not highlighted in Royale

and when we click on File Name the popup should be opened to save this File

In Royale when we click on Attachment File Name nothing happens
```

frd = new mx.net.FileReference();
frd.addEventListener(org.apache.royale.events.Event.OPEN, openHandler);
frd.save(file,name);

```

this functions doesn't triggered in Royale

Start by reproducing the attachment flow on the VDI, then inspect com/dbz/modules/AR/dbzSalesCommissionScheme.mxml and the shown mx.net.FileReference usage. Done means the attachment filename highlights with its row and clicking it opens the save popup so the file can be saved.
