Interesting Bug With Query Columns
 By Raymond Camden
An interesting bug (not a ColdFusion bug, but a user bug) cropped up in a discussion last week in the ColdFusion IRC channel.
Unfortunately I don't remember his IRC name, but after we worked together on this for an hour or so, he was kind enough to send me a real nice and simple code sample to replicate the issue.
So let's back up a bit and talk about what he saw. The user had a web service that returned a structure. Before he actually used it as a web service he did his testing locally like so:
As you can see, the function creates a query and then copies values to a structure. His real code was obviously a bit more complex. So he then switched to using a web service:
And something odd occurred. This is the output from running both his local and remote tests:
As you can see - the remote call returned a structure of arrays - not a structure of simple values. Why? While I can't answer why one method returned different data then the other, I can point out the problem with the code in the method. Notice how he copied the values from the query:
What helped diagnose this issue was inspecting the data he had in MyStruct. When he examined the particular Java class when invoked remotely, he saw that it was a QueryColumn (I don't have the full class name in front of me, but that is the approximate name), not a simple value as he would have expected.
