Uncaught TypeError: Cannot read property 'pq_detail' of undefined

[nuno.nogueira]

I get the error:

Code: [Select]

Uncaught TypeError: Cannot read property 'pq_detail' of undefined
When refreshing the data in the table.

It happens when the table is empty: I have no idea why this error is now being displayed now but it seems the table isn't properly refreshed when the table is empty.

Thanks for helping!

I should add that when deleting the last row of the table I get:

Code: [Select]

Uncaught TypeError: Cannot read property '0' of undefined

Is it a master detail grid?

When refreshing the data in the table.

Which one? master or detail

when deleting the last row of the table I get:

master or detail?

could you include a little test case?

[nuno.nogueira]

It is both (when deleting the last row of detail, you delete also the last row of the master).

In my application, I have new data per month (controlled with the links at the bottom "somar" and "subtrair".

When opening an empty month (for example Abril-2014) the table doesn't refresh and the error starts breaking the code.

Have a look at:

Your url is broken.

Have you copied the code to expand first row from the demo. You should check the length of data before expanding the row.

Code: [Select]

  if (data && data.length) {
     data[0]['pq_detail'] = { 'show': true };
  }

Hi,

The link isn't broken, but this forum is cutting part of the text.
You may see the example here: http://www.portal-gestao.com/or%C3%A7amento.html#

Go to an empty grid, clicking in "Somar" at the bottom and see the error.

I am not expading any rows.

This error is breaking the code,

I can see the error.

What does somar do. It looks like it refreshes the whole grid. What is the code of this function.

[nuno.nogueira]

It adds a month and refreshes the grid with the data of that month.
Subtrair deducts a month.

Here's the function being called:
[code]function mudaMes(acrescenta) {
      var dataCorrente = new Date(hoje.getFullYear(), hoje.getMonth() + acrescenta, 1);
      $('#mescorrente').html("Este m

In attachment you may see the code:

[paramvir]

your issue may be related to the wrong way you are refreshing the grid. You should not pass the whole constructor object while refreshing the grid.

Instead of that just pass the postData option and call refreshDataAndView

[nuno.nogueira]

It is related with the month change event, it seems.

I now get the error:

Code: [Select]

Uncaught TypeError: Cannot read property '3' of undefined
When changing the month to April.

This is the code I'm now using:

Code: [Select]

var obj = {
            dataModel: {
                postData: {
                    mesSelect: mes,
                    anoSelect: ano
                }
        };

        var $objOrcamento = $("#tabela").pqGrid(obj);
        $objOrcamento.pqGrid("refreshDataAndView");

}

Also  tried:

Code: [Select]

$.ajax($.extend({}, ajaxObj, {
            data: {
                mesSelect: mes,
                anoSelect: ano
            }
        }));

But it tells me that ajaxObj is not defined, although I moved it out of any functions.

I'm afraid to say it's still incorrect way to pass options to the grid.

Please go through the documentation on how to pass postData after initialization.

http://paramquery.com/pro/api#option-dataModel-postData

I also tried:

Code: [Select]

$( "#tabela" ).pqGrid( "option", "dataModel.postData", {mesSelect:mes, anoSelect:ano});

Which returns exactly the same error:

Code: [Select]

Uncaught TypeError: Cannot read property '3' of undefined
Although the request is sent to the server and returns:

Code: [Select]

{"data":[]}
Because there is No data for this month (April), which is correct.

The error is thrown only when the table is empty!

[nuno.nogueira]

Hello,

Can you help with this? How am I supposed to refresh the table?

Code: [Select]

$( "#tabela" ).pqGrid( "option", "dataModel.postData", {mesSelect:mes, anoSelect:ano});
Which returns an empty data JSON file. OK.

And:

Code: [Select]

$("#tabela").pqGrid("refresh");
Or:

Code: [Select]

$("#tabela").pqGrid("refreshDataAndView");
That does not refresh the main grid and returns the mentioned error in the details'.

[paramvir]

Could you use dev version of js and find out the line where exactly its throwing the error.
