Problem with Reload callback

tcardinal

I have a method which uploads data to the server using Ajax and returns a json object on success that says whether to reload the table or not. The object returned is:

{"reload": true, "afterReload": "updateOnReload"}

The afterReload value can be any function name with the right signature.

The important part of the method is

table = $("mytable").DataTable();

//repsonse is the parsed json

if (response.reload) {
   table.ajax.reload(function(json){eval(response.afterReload(table)});
};

this works as expected and the function called is as follows

function updateOnReload(table) {

 if (!table.rows().count()){
    table.button("big_step:name").disable();
    table.button("filter_step:name").disable();
 }
 else {
    table.button("big_step:name").enable();
    table.button("filter_step:name").enable();
 };
};

The issue I am having is that table.rows().count() is not returning the correct count - it seems to call the row count prior to loading the data, rather than after.

any ideas?

I update the callBack function to take the json and this is the json prior to the reload.

We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

Cheers,

I'll set it up and send you login details. probably Mondy

strange this one. It is all fine on the test server, just seems to be an issue on my dev machine. I'll leave this open for a bit, just in case it raises it's head on the test box.
