> Hi All,
> I'm new to Apache and open-source projects in general. So please bear with me.
> This one looks like a bug:
>
> {code:java}
> public class JsonPatchTest {
> ...
> @Test
> public void testReplacingObjectAttribute() { JsonObject object =
> Json.createObjectBuilder()
> .add("foo", Json.createObjectBuilder()
> .add("baz", new JsonStringImpl("1")))
> .add("bar", Json.createObjectBuilder()
> .add("baz", new JsonStringImpl("2")))
> .build(); JsonPatchImpl patch = new
> JsonPatchImpl(PROVIDER, new JsonPatchImpl.PatchValue(PROVIDER,
> JsonPatch.Operation.REPLACE,
>
> "/bar/baz",
>
> null,
>
> new JsonStringImpl("3"))); JsonObject patched = patch.apply(object);
> assertNotNull(patched);
> assertNotSame(object, patched); JsonObject o =
> patched.getJsonObject("foo");
> assertNotNull(o);
> assertEquals(new JsonStringImpl("1"), o.getJsonString("baz"));
> o = patched.getJsonObject("bar");
> assertNotNull(o);
> assertEquals(new JsonStringImpl("3"), o.getJsonString("baz")); //
> fails here
> assertEquals("{\"foo\":{\"baz\":\"1\"},\"bar\":{\"baz\":\"3\"}}",
> toJsonString(patched));
> } @Test
> public void testReplacingArrayElementAttribute() { JsonObject
> object = Json.createObjectBuilder()
> .add("foo", Json.createArrayBuilder()
> .add(Json.createObjectBuilder().add("bar", new
> JsonStringImpl("1")))
> .add(Json.createObjectBuilder().add("bar", new
> JsonStringImpl("2"))))
> .build(); JsonPatchImpl patch = new
> JsonPatchImpl(PROVIDER, new JsonPatchImpl.PatchValue(PROVIDER,
> JsonPatch.Operation.REPLACE,
>
> "/foo/1/bar",
>
> null,
>
> new JsonStringImpl("3"))); JsonObject patched = patch.apply(object);
> assertNotNull(patched);
> assertNotSame(object, patched); JsonArray array =
> patched.getJsonArray("foo");
> assertNotNull(array);
> assertNotSame(object.getJsonArray("foo"), array);
> assertEquals(2, array.size());
> assertEquals(new JsonStringImpl("3"),
> array.getJsonObject(1).getJsonString("bar"));
> assertEquals(new JsonStringImpl("1"),
> array.getJsonObject(0).getJsonString("bar")); // fails here
> assertEquals("{\"foo\":[{\"bar\":\"1\"},{\"bar\":\"3\"}]}",
> toJsonString(patched));
> }
> ...
> }{code}
> Basically I'm trying to do this:
> {code:java}
> { "action": "replace", "path": "/bar/baz", "value": "3"}
> {code}
> to this:
> {code:java}
> {"foo":{"baz":"1"},"bar":{"baz":"2"}}
> {code}
> and I get
> {code:java}
> {"foo":{"baz":null},"bar":{"baz":"3"}}
> {code}
> instead of
> {code:java}
> {"foo":{"baz":"1"},"bar":{"baz":"3"}}
> {code}
> Similarly when I do
> {code:java}
> { "action": "replace", "path": "/foo/1/bar", "value": "3"}
> {code}
> to this:
> {code:java}
> {"foo":[{"bar":"1"},{"bar":"2"}]}
> {code}
> and I get
> {code:java}
> {"foo":[{"bar":null},{"bar":"3"}]}
> {code}
> instead of
> {code:java}
> {"foo":[{"bar":"1"},{"bar":"3"}]}
> {code}
>
> The problem seems [to be
> in|https://github.com/stohu/johnzon/commit/515d363b8c55f0ba0835bda18f58dd545c0eb637]
> the removing method in JsonPointerImpl. The enclosed patch passed all the
> tests.
> (based on commit 515d363b8c55f0ba0835bda18f58dd545c0eb637 on master)
