6280 Midlet Upgrade fails with 'Operation Failed' - Bluetooth related

[richtea]

Environment:
------------
- Nokia 6280
- 12Mb free space
- midlet is 276kb, unsigned, run OK

WORKS:
--------
If I download the midlet onto the 6280 (instead of Bluetoothing), and then upgrade via a second download, the upgrade works as expected - with the appropriate checks about version is higher, and application source doesn't match, keep data yes/no.

FAILS:
-------
However, if the initial midlet was Bluetoothed onto the 6280 (instead of being downloaded), I get an 'Operation failed' error on trying to upgrade, when the jad is downloaded.

Can anyone explain why a downloaded midlet works, but a Bluetoothed one doesn't.

"Both the JAD and JAR must come from the same source as the original MIDlet suite."

Might it be to do with Bluetooth having a 'default/different domain?
If so, I would expect it to pop up a check - not fail.

One last little twist: if I download by Bluetooth but DON'T actually run the midlet, it upgrade again works. Not useful, but it may help the explanation.


Thanks in advance...

No idea either.

I have the feeling, the JAD is matched to the old JAR – however, I never debugged this and have given up to send a JAD+JAR to a Nokia Series 40 3rd Edition via Bluetooth when there is already a copy the MIDlet. Either just the JAR or delete the old MIDlet before. Everything else is too mysterious for me.

Of the new version, rename the JAR and the relative path to it in the JAD. When it works then, we all know the cause.

I skimmed quickly through the S40 Java installer design document, but I did any references to this kind of situation. I need to go through the doc again with more time in hand to find an answer. Maybe later this week.
