> Key: VELOCITY-873
> URL: https://issues.apache.org/jira/browse/VELOCITY-873
> Project: Velocity
> Issue Type: Bug
> Environment: VTL in user macro in Atlassian Confluence 5.9.4
> Reporter: Alexander Rosenberg
>
> This works as expected:
> {noformat}
> ## @noparams
> #set ($list = ["a", "b", "c"])
> #set ($num = $list.size()+1)
> <p>$num</p>
> {noformat}
> However, changing it to subtraction results in a {{ParseErrorException}}:
> {noformat}
> ## @noparams
> #set ($list = ["a", "b", "c"])
> #set ($num = $list.size()-1)
> <p>$num</p>
> {noformat}
> The error message given in atlassian-confluence.log:
> {noformat}
