Question about Storage.system.queryItems

Hi,

I've been testing the Kiva scenario. I have used the following FlexScript to find all items in the FloorStorage.But I could only find one item (actually there were five in FloorStorage ).

When i redefine the query parameter inside 'find Item'activity (From [Any Item] to [WHERE item.slot.slotItems.length > 0 ]). It can find all items correctly.

I'm so confused about this .Please help.

Thanks a lot.

I'm pretty sure the Find Item activity only finds one item by default - there is a clue to this in the manual where it states that when there is a list of queries it will stop evaluating them when the first item is found.

Sorry, I may not express clear.

The problem is not the Find Item activity.It's that when I modify the Find Item query, the label activity(allitems) gets a different value.

And I get the allitems label value from the following FlexScript :

Please see the model for details.

Thanks! I would provide any extra info if needed.

I could also replicate the issue without using the Find Item activity. Simply calling queryItems with the "Limit1" flag and an empty query string (which is what Find Item does, at least the manual says so) will cause the next queryItems command with an empty string to also only return one item.

It seems like a bug where the empty query strings somehow lead to the flag not being properly cleared.
