Resolution: Fixed

Patch applied.
> XPath functions for RESTful BPEL: combineUrl, composeUrl, expandTemplate
> ------------------------------------------------------------------------
>
> Key: ODE-281
> URL: https://issues.apache.org/jira/browse/ODE-281
> Project: ODE
> Issue Type: New Feature
> Components: BPEL Runtime
> Affects Versions: 1.1
> Reporter: Alexis Midon
> Assignee: Matthieu Riou
> Fix For: 1.2
>
> Attachments: ODE-281_#2_xpath_functions.patch

>
> Provide 2 new Xpath functions as described in the ODE wiki:
> __combineUrl(base, relative)__
> ----------------------------------------------------
> Takes the relative URL and combines it with the base URL to return a new
> absolute URL. If the relative parameter is an absolute URL, returns it
> instead.
> __composeUrl(template, [name, value]*)__
> __composeUrl(template, pairs)__
> ----------------------------------------------------
> Expands the template URL by substituting place holders in the template, for
> example, ('/order/{id}', 'id', 5) returns '/order/5'. Substitute values are
> either name/value pairs passed as separate parameters, or a node-set
> returning elements with name mapping to value. The functions applies proper
> encoding to the mapped values. Undefined variables are replaced by an empty
> string.
> Basically a uri is always returned.
> Compliant with the URI Template spec [1].
> __expandTemplate(template, [name, value]*)__
> __expandTemplate(template, pairs)__
> ----------------------------------------------------
> Same behavior as composeUrl except that undefined variables are *NOT*
> replaced by an empty string. The corresponding expansion pattern is not
> replaced. The immediate coensquence is that the function may return a
> template.
