Nathan Bubna updated VELOCITY-743:
----------------------------------

    Component/s: Engine
       Priority: Minor  (was: Major)
     Issue Type: Improvement  (was: Bug)

Sorry, this is intentional.  The colon is not a supported character in references.   It will certainly never be considered a valid reference character for standard $reference notation.

I'll leave this open as an RFE though, since i suppose it would be possible to increase the scope of legal reference characters in formal ${reference} notation.

For now, your best bet is probably to add the context to itself:

context.put("ctx", context);

and then do $ctx.get("EPL_JOBTITLE:varB_EPL") to give yourself more character freedom.

>          Issue Type: Improvement
>          Components: Engine
>    Affects Versions: 1.6.2
>         Environment: JRE 6, Apache tomcat 6.0.18

> I am trying to write a template that is customized like this
> -----------------------------------------------------------------------------
> <hi>
> <variable1> ${EPL_JOBTITLE:varB_EPL} </variable1>
> <variable2>${SPL_EMPLOYEENUMBER:varA_SPL} </variable2>
> </hi>
> -----------------------------------------------------------------------------
> Now the ${EPL_JOBTITLE:varB_EPL} is custom parsed and replaced with the appropriate values in the context.
> However, as soon as the Template is loaded by the velocity engine I get a 
> Template Parse Exception : 
> Encountered ":varB_EPL}\r\n\r\n\r\n" at MY Script - 1\Test this.vm[line 1, column 15]
> Was expecting one of:
>     "}" ...
>     <DOT> ...
> How is the ":" character an invalid one within braces ? Shouldn't it be supported within a variable name?
