|
|
* 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
