```
    Writes the given form load resource as JSON into the given writer. This will dump the full tree; use inlineValuesAsJson(SlingHttpServletRequest, Writer, String, int) for controlling the node depth.
    Can be used in JSPs to inline JSON for javascript code, for example:
```
 var data = <% FormsHelper.inlineValuesAsJson(slingRequest, out, "."); %>;
 
```
    which might result in:
```
 var data = { "jcr:primaryType": "nt:unstructured", "property" : "value" };
 
```
    If the path cannot be found, an empty object "{}" will be written. Any exception will be passed to the caller.
    The underlying form load resource must be based on a JCR Node. The path is relative and allows to specify subnodes. It cannot point to JCR properties, please use getValue(SlingHttpServletRequest, String, String) or getValues(SlingHttpServletRequest, String, String[]) for them.
    Parameters:
    
    request - the current request
    
    out - a writer, such as a JspWriter, to write the JSON into. Will automatically be flushed before and after.
    
    path - an absolute node path or a node path relativ to the current form load resource. Use "." for the resource node itself.
    
    Throws:
    
    RepositoryException - if some jcr error happened
    
    JSONException - if writing the json failed
    
    java.io.IOException - if there was a problem with the writer
