Ben Fortuna commented on SLING-8562:
------------------------------------
[~jsedding] apologies, I should have said script not "successfully" resolved.
:) I've just written a quick test to demonstrate each of the above suggestions:
{code:java}
Testing sling scripting (ESP) with FS resource:
{properties} = [org.mozilla.javascript.EcmaError: ReferenceError: "properties"
is not defined.]
{resource} = [/content/innersource/index]
{resource.valueMap} = [undefined]
{currentNode} = [/content/innersource/index]
{currentNode.name} = [java.lang.UnsupportedOperationException at
org.apache.sling.fsprovider.internal.mapper.jcr.FsNode.getNodes(FsNode.java:517)]
{currentNode.path} = [java.lang.UnsupportedOperationException at
org.apache.sling.fsprovider.internal.mapper.jcr.FsNode.getNodes(FsNode.java:517)]{code}
It appears that "properties" is not defined, and "resource" is defined but
doesn't have a "valueMap" property.
For "currentNode" it is also defined, but any property access seems to resolve
to the same FsNode.getNodes(String) method, which is not implemented.
I did have a look at the code and it appears that for currentNode.name or
currentNode.path it SHOULD be calling a different method that is registered
with Rhino via the "jsFunction_" method prefix, but I suspect this isn't
working anymore so it falls back on the getNodes(String) method.
> Unable to resolve ESP scripts loaded from Filesystem Resource Provider
> ----------------------------------------------------------------------
>
> Key: SLING-8562
> URL: https://issues.apache.org/jira/browse/SLING-8562
> Project: Sling
> Issue Type: Bug
> Affects Versions: Scripting Core 2.0.46, File System Resource Provider
> 2.1.16
> Reporter: Ben Fortuna
> Priority: Major
>
> A simple test fails when trying to load a resource via Sling Filesystem
> Resource Provider.
> /content/sample/index.json:
> {code:java}
> {
> "sling:resourceType": "sample/page/index",
> "jcr:primaryType": "nt:unstructured",
> "title": "Sample App"
> }{code}
>
> /apps/sample/page/index/html.esp:
> {code:java}
> <html>
> <head><title>${currentNode.title}</title></head>
> <body></body>
> </html>{code}
>
> When both content and app are mounted via Filesystem Resource Provider config
> the following error results:
> {code:java}
> Internal Server Error (500)
> Exception:
> java.lang.UnsupportedOperationException
> at
> org.apache.sling.fsprovider.internal.mapper.jcr.FsNode.getNodes(FsNode.java:517)
> at
> org.apache.sling.scripting.javascript.wrapper.ScriptableNode.get(ScriptableNode.java:319)
> ...{code}
>
> Basically the javascript renderer tries to call `Node.getNodes(pattern)` to
> resolve the property `currentNode.title` but Filesystem Resource Provider
> doesnt support this method.
