RFC 6901 op:replace & arrays

[ArkadiuszRaj]

In json file I have an array with 4 strings.

"OBJECTS":{
                    "IMAGE":{
                        "ENABLED":true
                        ,"FILE": [
                            "JPEG"
                            ,"PNG"
                            ,"TIFF"
                            ,"FITS"
                        ]
                    }

I am applying patch (op:replace) which shall replace array with new content, this time 3 strings.

{"op":"replace","path":"...","value":["PNG","TIFF","FITS"]}

As result array has still 4 elements, last one "survived" patch operation

"OBJECTS":{
                    "IMAGE":{
                        "ENABLED":true
                        ,"FILE": [
                            "PNG"
                            ,"TIFF"
                            ,"FITS"
                            ,"FITS"
                        ]
                    }

I think whole array shall be replaced.

Can you provide a complete example for both the value and the patch?

Hi Niels,
First of all Happy New Year!
Since I was misled, i.e. the patch path parameter is generated and uses the array expansion, there is no error in the code. Sorry for the confusion!

[{"op":"replace","path":"/PREVIEW/IMAGE/AVERAGING","value":15},
{"op":"replace","path":"/PREVIEW/IMAGE/RESCALE","value":1},
{"op":"replace","path":"/PREVIEW/INTERVAL","value":30},
{"op":"replace","path":"/REPORTER/CONFIGURATION/PREVIEW/OBJECTS/IMAGE/FILE/0","value":"PNG"},
{"op":"replace","path":"/REPORTER/CONFIGURATION/PREVIEW/OBJECTS/IMAGE/FILE/1","value":"TIFF"},
{"op":"replace","path":"/REPORTER/CONFIGURATION/PREVIEW/OBJECTS/IMAGE/FILE/2","value":"FITS"}]

Happy new year to you, too!
