jQuery Grid Plugin - jqGrid

Hi, everyone.

I've just noticed some odd behaviour (well, unexpected to me, anyways) regarding subgrids and grouping. If I put in grouping code:

        grouping: true,
        groupingView : {
            groupField : ['currency'],
            groupSummary : [true],
            groupColumnShow : [true],
            groupText : ['<b>{0}</b>']
        },

into my config block, then the subgrid doesn't work - it doesn't show the + column beside each line. If I take that out, though, the subgrid works just fine. Is there a limitation to this, in that it's a one-or-the-other situation?

Also, is there a way to have two user-defined footer rows? If I can do that, I can safely turn off the grouping and the first problem becomes a non-issue.

Thanks!
