I just attempted to upgrade my dev environment from jqGrid 3.6.4 to 3.6.5, and found that the new version results in no rows being displayed on any of my grids. There are no errors being returned by jqGrid; the grid and its associated pager are simply blank. I'm returning the data to the grid in a JSON format, if that makes any difference.

Has the format the grid is expecting back for JSON records changed?

For now, I have simply reverted back to 3.6.4, and everything appears to be working as well as always.

Thanks,

I know it's no help to you, but I've got the same issue upgrading from 3.6.2 to 3.6.5. Also using JSON. No data displayed.

There's clearly a serious breaking change somewhere!

This is my code that works beautifully in 3.6.2 (it's requesting the data correctly and getting exactly the same JSON data that works with 3.6.2):

Hello,

@Inara – I'm not sure what is going with this, but if you send me a link to the problem I maybe can help.

Also which version of jQuery is used?

Best Regards

Tony

Tony,

Thanks for catching that trailing comma (it was being auto-generated by one of our code tools), but it doesn't appear to be what was causing the issue. I removed the comma in question, and the grids are still loading blank, with no associated error messages. The older versions of jqGrid (3.6.4 or less) seem to work with or without the comma in place, and the new versions fails with or without it in place.

Regards,

Matt

Hello,

Can you write by hand a simple grid – not generated from some code and test with the new version.

I feel that some not accepted chars are send to the grid configuration which causes this problem.

Tony,

I created a very simple, single-column grid, as follows:

Hello,

Better provide a link to the problem. If possible do not include the min version, but the development one.

Thank you

Tony,

Unfortunately, I do not have a public webserver available to host a demo file on at this point in time. Is there any chance you could provide the source for v3.6.4 so I could run some tests comparing the two? I have the min version of 3.6.4, but not the source.

Thanks,

Matt

After a long debug/trace session with firebug, I finally found the source of the issue. It appears that the jqGrid 3.6.5 only supports strictly formatted JSON, with quotes around the name and value of each key. I tested flipping back and forth between 3.6.4 and 3.6.5 and dropping/adding the quotes in each to confirm that this was the problem. To use my example from above, the return data must be formatted as follows for jqGrid 3.6.5:

Hello,

First of all thank you for this investigation.

The Long Story (for 3.6.5):

In order to support JSONP correct we switch from complete ajax event to success one.

This causes to overcome jqGrid parse function.

In the success event jQuery makes his own validation for the json object and if the json format returned from the server is not correct
