[jira] Commented: (VELOCITY-743) The character ":" if present
within the curly braces of a variable throws exception
[ https://issues.apache.org/jira/browse/VELOCITY-743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929588#action_12929588 ]
Jarkko Viinamäki commented on VELOCITY-743:
-------------------------------------------
I think the regexp for allowed reference names should be the same in both formats (with and without curly braces). Otherwise it's inconsistent. So -1 for this RFE idea.

> Key: VELOCITY-743
> URL: https://issues.apache.org/jira/browse/VELOCITY-743
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.6.2
> Environment: JRE 6, Apache tomcat 6.0.18
> Reporter: Vinay
> Priority: Minor
>
> 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?
