findclass match on empty string
We have this code:
findclass [findstr [HTTP::uri] "FeReqHdlg=" 10 "&"] $::FEserverClass
When the findclass command runs, looking up the empty string in the indicated class, it always returns the first member of the class, rather than also returning an empty string.
I was hoping to verify whether this is expected behaviour before we open a Support case.

- It sounds like this is not behaving as expected. If you search a class for a null string, it shouldn't spit back the first entry.

Mind posting the version you are seeing this behavior on deb? Is it all versions? - 9.2.3 is the version my customer is using, and I have no insight into what other versions may be affected.
I have opened a case, waiting for a CR , will post it when I get it so you can watch the release notes for the fix.
In the meantime, you just need to validate any variable value you want to push into findclass. My customer coded around the issue by checking for null string and replacing with "-":set FEHandler [findstr [HTTP::uri] "FeReqHdlg=" 10 "&"] if { [string length $FEHandler] == 0} { set FEHandler "-" } ...[findclass $FEHandler $::FEserverClass]...
/deb - Good point. Can't remember why they took that approach, but it seemed to make sense at the time...
CR68074 (for Sonoma) and CR68076 (targetted for 9.3.0) have created to track this issue.
/deb - Good to hear, thanks for the update.
