Éamonn McManus updated VELOCITY-961:
------------------------------------
Description:
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> ...
"{" ...

"\\\\" ...

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}
