Datatables _fnSetObjectDataFn function does not store array types correctly

[jimjaeger]

Fix for _fnSetObjectDataFn required to handle storing of array types correctly.
Already open a forum entry. Also I already fixed it on a local branch. If you give me rights for branch upload I can provide the fix to you.

• arrayNotation = aLast.match(__reArray);
  +var join = arrayNotation[0].substring(1, arrayNotation[0].length-1);
  +var r = val.length > 0 ? val.split(join) : [];
• data[ aLast.replace(__reArray, '') ] = r;
• data[ aLast.replace(__reArray, '') ] = val;

Thanks. Could you give me a link to the forum thread please? Does it give details on example data showing the issue as it was?

Pull requests can be sent to the master branch here and I'll consider them for inclusion.

Unit tests are something that DataTables is currently lacking for these methods, although they are inbound.

I found it here.

If you could please link to a test case showing the issue that would be great.

Hi,

here is an example of data for testcase:
{"total_rows":104,"offset":0,"rows":[ {"id" : "myid", "doc" : {"tags" : ["tag1"],"_id" : "myid", "_rev" : "3-188272" } }]

sample table config:

var table = $('#dataTables-projectmetadata').DataTable({
responsive : true,
paging : true,
fixedHeader : true,
stateSave : true,
sAjaxDataProp: 'rows',
rowId: 'id',
"ajax": "/api/metadata",
"columns": [
{ "title": "ID", "data": "id" },
{ "title": "Tags", "data": "doc.tags[, ]", "defaultContent": "" }
]
});

After I modify the entry the new value is now {"id" : "myid", "doc" : {"tags" : "tag12","_id" : "myid", "_rev" : "3-188272" } }

from array to string ....

I guess I have to create a branch and send a pull request after my changes, but I have not access rights to create a branch.

Thanks! Let me look into it, but in the short term I would recommend using:

{ "title": "Tags", "data": "doc", render: 'tags.[, ]', "defaultContent": "" }

That takes the array setter out of the equation.

I already fixed it for me and it works for array and non array values. If you give me branch permission I can provide the fix.

Thanks - going to close this thread in favour of the PR you opened - #83. I'm just working my way through e-mails and forum stuff from the weekend so it will be a little while before I can respond there, but I'll review it shortly.
