> Parsing regression in Velocity 2.3
> ----------------------------------
>
> Key: VELOCITY-961
> URL: https://issues.apache.org/jira/browse/VELOCITY-961
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 2.3
> Reporter: Éamonn McManus
> Assignee: Claude Brisson
> Priority: Minor
>
> The following template parses correctly with Velocity 1.7:
> {noformat}
> $child.typeName()#if($child.isRepeated())[]#end{noformat}
> But with 2.3 it gets an exception:
> {noformat}
> org.apache.velocity.runtime.parser.TemplateParseException: Encountered "[" at
> velocityParsingBug[line 1, column 42]
> Was expecting one of:
> "\u001c" ...
> "\u001c" ...
> "||" ...
> "|" ...
> "(" ...
> ")" ...
> <ESCAPE_DIRECTIVE> ...
> "]]#" ...
> <WHITESPACE> ...
> <NEWLINE> ...
> <SUFFIX> ...
> <STRING_LITERAL> ...
> <INTEGER_LITERAL> ...
> <FLOATING_POINT_LITERAL> ...
> <DOT> ...
> "{" ...
> "}" ...
> "\\\\" ...
> "\\" ...
> <TEXT> ...
> <INLINE_TEXT> ...
> <EMPTY_INDEX> ...
> "{" ...
> "\u001c" ...
> <WHITESPACE> ...
> <NEWLINE> ... at
> org.apache.velocity.runtime.parser.StandardParser.parse(StandardParser.java:198)
> at
> org.apache.velocity.runtime.RuntimeInstance.parse(RuntimeInstance.java:1341){noformat}
> I think the template is correct and should work with both versions.
> I was able to work around the bug like this:
> {noformat}
> $set ($squares = '[]')
> $child.typeName()#if($child.isRepeated())$squares#end{noformat}
