Using CFThrow to rethrow?

[Steve Sommers]

I was wondering if it's possible to, or if anyone has emulated a <CFRETHROW> with a <CFTHROW> call?

Here's basically what I'm trying to accomplish:

[-__cfSearching__-]

I have not used this personally, but it appears to work

<cfif myCfCatchActive>
<cfthrow object="#myCFCatch.Cause#">
</cfif>

My ears popped up, and I optimistically tried the myCFCatch.Cause method and bummer -- "Element CAUSE is undefined in MYCFCATCH"

What version of CF are you using? I'm using MX8.

[-__cfSearching__-]

Weird, I am using CF8 as well. Here is the test code I used

[-__cfSearching__-]

If perhaps you meant MX7, try using RootCause instead.

<cfif myCfCatchActive>
<cfthrow object="#myCFCatch.RootCause#">
</cfif>

[Steve Sommers]

Ah, you are right that I am using MX7 -- I have MX8 on my notebook and MX7 on my desktop - my bad. RootCause is also undefined for my MX7 test. I have not tried this test on 8 yet.

BTW, my test case is as follows:

[-__cfSearching__-]

This is close, but not quite. It does display the correct error message, but reports the error as occuring on the <cfthrow> line. Interestingly, my test case generates a java.sql.SQLException and the error line numbers are reported correctly. So apparently, not all exceptions are alike. Perhaps coldfusion runtime exceptions (ie like coldfusion.runtime.UndefinedVariableException) are handled differently.

Thanks for the suggestion. I wish it would have worked. Maybe someone from Adobe will read this and make the Cause object work for all exception types.

Anyway, I coded around this by storing the CFCatch as shown above and modifying my error display page to use this stored copy instead of the current CFCatch copy if a specific user defined error is thrown "UnhandledException.FinalGasp", which I throw if I detect this condition in my postProcess (I'm using Fusebox).
