> Template parsing of expansions can't handle map expressions
> -----------------------------------------------------------
>
> Key: TAP5-1605
> URL: https://issues.apache.org/jira/browse/TAP5-1605
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.3
> Reporter: Robert Zeigler
> Assignee: Robert Zeigler
>
> 5.3 introduced map support into the property expression language in the form:
> {'foo': 'bar'}.
> Expansion parsing chokes on the syntax, however. It uses a reluctant regular
> expression to find the closing brace:
> private static final Pattern EXPANSION_PATTERN =
> Pattern.compile("\\$\\{\\s*(.*?)\\s*}");
> Which means that the use of a map inside an expansion prematurely terminates
> the exansion:
> ${echoMap({"foo": "bar"})}
> The regex finds the first } and the expression evaluates as:
> echoMap({"foo": "bar"
> Which is clearly incorrect.
