I'm seeing some weird behaviour with the map data type. I'm trying to
convert a list of attachments to a map of attachments. I have a map with
subtype Document. I'm using a loop to iterate over the list and add
the attachments to the map. My problem is that the first time through
the loop, the map key is always being set the the value of the variable
used in the route condition (i.e. if I start the loop at 1, the map key
is set to an int value of 1, if I start the loop at 2, the map key is
set to 2). The second time through the loop, the proper key is being
used (which is a string value) and causes a java.lang.NumberFormatException.
If I add a value to the map before entering the loop, everything works ok.
Before entering the loop I have a variable mapping of:
/process_data/@count = count(/process_data/attList)
/process_data/@idx = 0
I have a conditional route of:
/process_data/@idx < /process_data/@count
And inside the loop, I have variable mappings:
/process_data/@idx = /process_data/@idx + 1
/process_data/@attName = getDocAttribute(/process_data/attList[number(/process_data/@idx)],"name")
/process_data/attMap[@id=/process_data/@attName] = /process_data/attList[number(/process_data/@idx)]
The first iteration always results in a map key equal to the value of the idx variable.
Not sure if I'm doing something wrong, or there's a bug.
