Lars Trieloff updated SLING-789:
--------------------------------

    Attachment: SLING-789.patch

This patch extends SlingScriptHelper with an retrieve method that works just like the include method but returns a String. The implementation of this method creates an ServletResponseWrapper to record the output stream and to make it available as a String return value.

> I have a use case where I want to create a script that takes the output of another script and admonishes it. For the simple case where I just want to add some content before and after the original script SlingScriptHelper.include is sufficient, but if I have to deal with the output, e.g. to add additional escaping, it would be helpful to be able to redirect the response body of one script into a String variable of another script, just like the import tag in JSTL does.
