ListGrid.showRowNumbers and grouping by two columns

[claudiobosticco]

v8.2p_2012-04-04/PowerEdition

I see that showRowNumbers:true, coupled with a grouping with two columns, i.e. modifing #columnOrder sample by adding to 'countryList':

showRowNumbers :true,
groupByField:['continent', 'countryName']

makes the row numbering to reset for every 'upper level group', as in the attachment.

Is there available a way to have the numbering not resetting, like in a single column grouped grid?

In this case it's best to create your own rowNumbering column if you want that specific behavior.
