Bug(?) CFMX return value functions

[JorritJ]

Hi,

I think I have found some sort of bug when you directly output the returned
value in a function. ColdFusion seems to insert a whitespace before the
returned value to a string.
Here's an example:
The first image is broken because the image adds a whitespace between
"159x120/" and the image name. Setting it to a variable first seems to work.
Any idea's?



<cffunction name="fnReturnImage">
<cfreturn "159x120_box_cfmx7">
</cffunction>

<cfoutput>
Direct output: <br>
<img
src="http://www.macromedia.com/images/shared/product_boxes/159x120/#fnReturnImag
e()#.gif">
<cfset imageSrc = fnReturnImage()>
Set to a var first: <br>
<img
src="http://www.macromedia.com/images/shared/product_boxes/159x120/#imageSrc#.gi
f">
</cfoutput>

It's well documented (on these and other forums, anyhow ;-), and "expected
behaviour" (that's not to say it's not *crap* expected behaviour).

Add output="false" to your <cffunction> tag.

Put output="false" in ths cffunction tag and it will fix it!



<cffunction name="fnReturnImage" output="false">
<cfreturn "159x120_box_cfmx7">
</cffunction>

<cfoutput>
Direct output: <br>
<img
src="http://www.macromedia.com/images/shared/product_boxes/159x120/#fnReturnImag
e()#.gif">
<cfset imageSrc = fnReturnImage()>
Set to a var first: <br>
<img
src="http://www.macromedia.com/images/shared/product_boxes/159x120/#imageSrc#.gi
f">
</cfoutput>

Argh! Yes it sounds logical if you think of it.
Why didn't I think of this! :(

The folowing code works as well (without the output="no" option). So it is
expected behavour!



<cffunction name="fnReturnImage3"><cfreturn "159x120_box_cfmx7"></cffunction>
