problem with aggregate count

[steev]

I'm trying to get the number of items in a group:

grpsum["Central","vfs.fs.size[/repository,used]","count","0"]

this eventually becomes 'not supported' and i'm not sure why.

this works fine, however:

grpsum["Central","vfs.fs.size[/repository,used]","last","0"]

I'm left scratching my head at where I went wrong.

Aggregate items are tricky. If even one item in the group becomes unsupported for any reason, the aggregate item also becomes unsupported.
