The site mesh decorator not working with special characters

[sabtharishi]

The site mesh decorator is applied for for generic URL pattern like,

<decorator name="wfc_template" page="wfc.jsp">
<pattern>/wf*</pattern>
</decorator>
But the decorator is not applied for specific URL like,

<decorator name="newUI_template" page="newwfc.jsp">
<pattern>/wf/xxx-flow*</pattern>
</decorator>

it seems patterns are not understood by the sitemesh when they contains special characters. In this case it is "-" hyphen between the "xxx" and "flow"
