#...# expression leaves superflous space behind for the first #

hi there

I run CF 9.01 and have a nasty white space problem:

I populate a form field like this:

---

... value="#application.utils.FormatTS(now())#" ...

---

This leaves behind in the source code generated the followng:

----

value=" 2011-01-22 03:34:03"

---

The empty space later generates a problem. I have observed this bug throughout all versions of CF. One can avoid this in all situation where one can concatenate strings like in "some test" & application.utils.FormatTS() ... this will not geneate the empty space.

CF's IsDate () returns NO if the space is there ...LSIsDate () returns YES ... inconsistent behavior IMHO.

BTW: The function FormatTS () does NOT generate the leading space. It is the way how CF generates the code

BTW: I know that I can get rid of the space with trim() ... however, it's a mess to be forced to do so in ALL processing of such constructs ...

Any remedy known for this? Or any reason WHY CF does it like this? How can I seduce it not to generate suc code?

Thanks

Martin

    Are you positive? Because that certainly is the most likely cause. Check the cffunction and make sure you have set output="false".

    Yes, I am sure

    This is the cfc wth the method

    ---

    <cfcomponent output="false">


       <cffunction name="FormatTS" access="public" returntype="string" hint="Returns a timestamp formatted as yyyy-mm-dd hh:mm:ss">

          <cfargument name="Timestamp"           type="any"    required="yes">

          <cfargument name="Date_Time_Separator" type="string" required="no" default=" ">

          <cfreturn (arguments.Timestamp gt "" ? DateFormat (arguments.Timestamp, "yyyy-mm-dd") & arguments.Date_Time_Separator & TimeFormat (arguments.Timestamp, "HH:mm:ss") : "")>

       </cffunction>

    ---

    Howerver, I see that I can also set output="false" in the method. I was not aware that this MUST be done ... cause obviously, when doing so, the superfluos space does disappear .... so, your comment helped. Strange, I don't understand the difference right now .. anyway.

    You need to specify output="false" on the function too.

    (Update: I responded via email before I saw your edit.)

    The documentation says it controls whether "the entire function body is processed as if it were in a cfoutput tag...". (and functions do not inherit the setting of the parent cfcomponent tag). I cannot say I always understand how certain code ends up creating the whitespace in the first place. But as it is easily fixed, I never spent that much time investigating.
