colReorder.order() issue with columnDefs.data()

MichaelBrade

Hi, if I initialize my table with colReorder, using a columnDefs for all columns of a specific object:

    columnDefs: [ {
          targets: "attr",
          data: function(data, type, value, meta){
            var api, col;
            if (type === 'set') {
              console.warn("setting values not supported!");
              return;
            }
            api = meta.settings.oInstance.api(true);
            col = meta.col;
            try {
              col = api.colReorder.order()[meta.col];    // because here it crashes during init
            } catch (e$) {
              console.log("not yet");
            }
            
            return this$.getAttribute(data, col);
          }
        ...

then I get a crash because colReorder is initialized after data() is called, i.e., the preInit event is fired after data(). Is that intentional? My workaround is the try {} catch () {} above but this is not a nice solution.

Also, talking about this, why do I need to call colReorder.order() at all? I would change the API so that meta.col is the original column index, not the currently rendered column. Only then colReorder would be transparent to use.

Hi Allan, any comment on this? Are you busy with other things and this has a low priority, or do you need more information, or...?

As I wrote, IMHO the ideal solution would be to change the meta.col argument to be independet of ColReorder in columnDefs.data() and columnDefs.render().
