Alexander Rosenberg created VELOCITY-873:
--------------------------------------------
Summary: Subtraction without spaces results in parse error
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}
