- * Following code is a replacement for above line. In the case of multiple values, it
- * presents the user with a dialog containing a list from which he can select the value
- * he wants. However it is being commented out for now because of several problems, namely
- *
- * 1. There is no easy way to put localizable strings for the title and message of
- * the dialog without introducing a .properties file which currently doesn't exist
- * 2. Using blank title and messages as shown below have a problem because a zero-length
- * title is being displayed as some garbage characters (which is why the code below
- * has a title of " " instead of ""). This is a separate bug which will have to be
- * investigated further.
- * 3. The current wallet tables present alternate values for items such as shipping
- * address -- namely billing address and home address. Up until now, these alternate
- * values have never been a problem because the preferred value is always first and is
- * all the user sees when doing a prefill. However now he will be presented with a
- * list showing all these values and asking him to pick one, even though the wallet
- * code was clearly able to determine that he meant shipping address and not billing
- * address.
- * 4. There is a relatively long delay before the dialog come up whereas values are
- * filled in quickly when no dialog is involved.
- *
- * Once this feature is checked in, a separate bug will be opened asking that the above
- * problems be examined and this dialog turned on
