Proper aggregated file sizes [message #647629]

Hi

I'm creating a report with a table that lists the size of a bunch of files. These files vary greatly in size between KBs and GBs. Their size is given to me in bytes. Currently I format the file sizes into correct KB/MB/GB units with the Expression Builder.

But I also want a sum of the file sizes at the end of the table. I have created a Aggregation in the end of the table that sums the file sizes in bytes together. But I want that aggregation to also display correct units in either KB, MB or GB. I have noticed that the Expression Builder behaves differently for aggregations so I can't use the same solution for them.

In the aggregate items onCreate script use the setDisplayValue function
like:

//get the value
var myval =this.getValue();
//modify it and
this.setDisplayValue(myval +"Kb")
