support for multivalued atttributes?

currently, the sdb management tool does not expose multivalued attributes at all can this support be added? we use multivalued attributed heavily to store data and not being able to see all the values for a given attribute makes this tool hard to use.

Just to let you know, we are investigating adding support for multivalued attributes.  Should have more news for you by later this week or early next week.

We have now implemented support for this and you can download the free version from the Downloads tab or the full version from the store.  See http://www.mindscape.co.nz/blog/index.php/2009/07/19/multi-value-attributes-in-simpledb-management-tools/ for more info.

you guys are awesome

I have found that multi-value attributes seem to have worked before, but now every time I Save Changes from the SimpleDB management tool, multi-value attributes are lost. This may be related to the fact that I recently upgraded to Lightspeed Pro, but I uninstalled the simpledb management tools, downloaded the current version and reinstalled. Same behavior. I can add multiple values to an attribute, but with each Save Changes it appears that they are lost, with only one value remaining.

Thanks for reporting this, Steve.  We've had a similar report from another customer and we haven't been able to reproduce the problem ourselves, but this seems to confirm that something is wrong.  We will investigate further and let you know.

We have a known issue where you need to click away from the line that you're editing (before clicking Save Changes) in order for changes to be detected.  Could you confirm that you see the problem even when you do this?  Thanks!

Is the "one value remaining" a value that was there before you started editing, or is it one of the ones you have added?  (For example, if you create a new item and apply multiple values to one of its attributes, does it end up with an empty value or with a random one of the attributes?)  Put another way, when you do a SaveChanges, is it that you're seeing your edits not take effect as a whole, or is it very specifically that attribute values beyond the first are being lost?  I'm wondering if SimpleDB eventual consistency is involved, e.g. if I'm getting lucky with my test domains while you're getting refreshed from another server which hasn't yet received your updates...

I just confirmed it is not related to eventual consistency. It is behaving as if the multi value attribute changes are not persisted. I'll give another go tomorrow to try to isolate what the edit really is doing

FYI we have just uploaded a new build of SimpleDB Management Tools which makes a couple of minor tweaks in the hope of addressing this problem.  We still haven't managed to reproduce the problem, so I'm not too optimistic, but it will at least remove a couple of avenues of suspicion.  It is available for download from the store so if you could update to that before picking this up again then that would be great.  We're sorry for the inconvenience and appreciate your help.

Here is my test result from this morning, I can reproduce the error: Testing multi values Created new record Added 2 values to one attribute seemed to be there Close the results window, re-open domain table 2 values still there Edit existing record edit attribute, click Edit Values... original value = 123456789 Add 2nd value = 888888888 Ok Ui shows 2 values Click on Save Changes Run Query, only has 123456789 Close the results window, re-open With the same attribute of existing record, Edit Values... Change 123456789 to 111111111 Add 2nd value = 222222222 Close dialog, UI shows 2 values Hit Save Changes Run Query attribute resets back to 123456789 Edit new record created above in test #1 a different attribute has value "test" Edit Values... change "test" to 'quest' add 2nd value 'guest' Ok UI shows 2 values Save changes Run query attribute now has only 1 value, reset back to "test"

Thanks for the additional info and detailed repro steps.  I just want to get a few more details about this test:

Edit existing record edit attribute,
click Edit Values... original value = 123456789
Add 2nd value = 888888888
Ok Ui shows 2 values
Click on Save Changes Run Query, only has 123456789

After exiting the Edit Values dialog, did you click on another row or in the query area before clicking on Save Changes, or was the focus still on the cell you'd just edited?

Could you re-run this test and, after OKing the dialog but before clicking Save Changes, click in the query text box?  I.e. click OK, UI should show two values, click in the query text box, click on Save Changes, click on Run Query.  And let us know whether what is showing for the edited attribute after re-running the query.  Thanks!
