CFSAVECONTENT in CFAJAX calls

When a multiline string is returned from a CF function used with CFAJAX, the engine seizes on the line breaks. This is easy to work around using ReReplace():

<cfset MyReturn = ReReplace(MyReturn,"[#CHR(10)##CHR(13)#]","","ALL")>

There is a second issue with CFSAVECONTENT specifically, in that the core CFAJAX include has this in it:

<cfsetting enablecfoutputonly="yes">

which means you need to add CFOUTPUT tags around your content inside the CFSAVECONTENT tag.

<cffunction name="TestSaveContent" returntype="string" output="true">
<cfset var MyReturn = "">
<cfset var MyString = "Hello">
<cfsavecontent variable="MyReturn">
<cfoutput>
<p>#MyString#</p>
<p>Goodbye</p>
</cfoutput>
</cfsavecontent>
<cfset MyReturn = ReReplace(MyReturn,"[#CHR(10)##CHR(13)#]","","ALL")>
<cfreturn MyReturn>
</cffunction>
