Weird transaction issue with implicit struct (and possible array)

[Jeremy Tan]

I have the following 2 files.

mycfc.cfc

<cfcomponent  output="false">

          <cffunction name="set" output="true" returntype="void">

                    <cfargument name="text1" type="string" required="true">

                    <cfargument name="something" type="any" required="true">

                    <cfdump var="#arguments#">

          </cffunction>

</cfcomponent>

mycfc.cfm

<cfscript>

          test = {firstName="Bob in line 2"};

          i=1;

          transaction {

     new mycfc().set(Text1:"hello",something:"Bob in text");

     i++;

     new mycfc().set(Text1:"hello",something:"Bob in text again");

     new mycfc().set(Text1:"hello",something:test);

     new mycfc().set(Text1:"hello",something:{firstName="Bob in line 9"});

     test2 = {firstName="Merry"};

     writeDump(var=test2,label="line 11" );

     new mycfc().set(Text1:"hello",something:{firstName="Jenny"});

     i++;

     new mycfc().set(Text1:"hello",something:{firstName="Jenny 2"});

          }

          writeDump("i = #i#");

</cfscript>

If you run the mycfc.cfm, you will notice 4 weird things here.

1) new mycfc().set(Text1:"hello",something:test); should output "Bob in line 2", but is replace with "Bob in line 9"

2) my dump with label="line 11" is missing.

3) duplication of "Jenny 2", even you remove the writedump, you still get double "Jenny 2".

4) writeDump("i = #i#"); will give you "i = 2", which should be i = 3

This problem only happen when using transaction. It is happen to both CF9 and CF10

You shouldn't use the colon to separate argument name=value pairs.  It's undocumented, use = instead

     new mycfc().set(Text1:"hello",something:"Bob in text");

should be

     new mycfc().set(Text1 = "hello",something = "Bob in text");

Apart from that I couldn't say for the other strangeness you're experiencing.  I've seen problems using inline structures being passed as arguments, try creating them as variables and passing those instead

The colon _is_ documented and supported in CF10.

Thanks duncancumming.

I just found a workaround for that issue. That is if I don't use the argument name, the problem go away...

<cfscript>

          test = {firstName="Bob in line 2"};

          i = 1;

          transaction

          {

                    new mycfc().set("hello", "Bob in text");

                    i++;

                    new mycfc().set("hello", "Bob in text again");

                    new mycfc().set("hello", test);

                    new mycfc().set("hello", {firstName="Bob in line 9"});

                    test2 = {firstName="Merry"};

                    writeDump(var=test2, label="line 11");

                    new mycfc().set("hello", {firstName="Jenny"});

                    i++;

                    new mycfc().set("hello", {firstName="Jenny 2"});

          }

          writeDump("i = #i#");

</cfscript>

I had a look at this, and it's a variation of a bug we (Duncan: you and I) experienced a while back, and that Brad Wood helped me lock down to a decent repro case. I blog about this current example - with links to various bugs and older blog posts - here: http://adamcameroncoldfusion.blogspot.co.uk/2013/02/another-serious-struct-literal-syntax.html

It's more serious (well: less of an edge-case, anyhow) than this example makes it look.
