Hi,

Ruby 1.8.6  
Rails 1.2.6

I have a simple @conditions variable setup in a controller’s “list”  
method. It looks something like:

[“abbr = ? and (start\_date between ? and ?)”, “AZ”, ‘2008-08-01’,  
‘2008-08-31’]

From any given view, I pass that variable back to the “export” method  
if they want to export a list of records to a CSV file:

link\_to(  
image\_tag(‘export.png’, :alt =\> ‘Export to CSV file’),  
:action =\> ‘export’,  
:conditions =\> @conditions  
)

What I’ve noticed, however, is that it sometimes mangles the array and  
the order of the array, and I end up with:

[“2008-08-01”, “2008-08-31”, “AZ”, “abbr = ? and (start\_date between ?  
and ?)”]

I’m definitely not altered the array myself, and it doesn’t always  
happen, either. I’m completely baffled by this. What’s happening?

Thanks,

Dan
