On table reload, "Uncaught TypeError: Cannot read property 'yadcf_data_0' of null"

[EMTurano]

I updated to the latest stable release of YADCF, and the latest versions of DataTables and Editor. This error doesn't always occur when the table is reloaded, only some of the time.

Not sure to which version your refering as latest stable, but try the newst from repo, and if still happens provide a link to the page so I can check it there

Updated to the latest beta. A few notes:

-This issue only occurs when an item on the table is deleted, and the page is reloaded.
-When an item is edited, it is successfully edited.

From my quick check it seems that there is a different error before the one you reported

see console log:

Object {action: "remove", data: Object}
With JSON:
Object {data: Array[0]}
With action:
datatables.include-footer.1668b7.js:formatted:53397 remove
Uncaught TypeError: Cannot read property '0' of undefined
rowID=row_3147

Then after doing page refresh indeed your reported issue appear, its very easy to fix that error on yadcf side- (null check for the json coming back on table loading, BUT I never seen a scenario in which the json is coming back as null, so If you want I can add that null check on yadcf, but itd sure doesn't look healthy, IMO you should also find out why the json comes sometimes as null.

Could you point me in the direction to find out why it’s coming back as null? It doesn’t always do that, but it does sometimes when the page is reloaded.

I would go and check your server code and try to debug and find out why it doesn't return a proper data

[EMTurano]

I wanted to send another issue your way. When DataTables Responsive is used and hidden rows are shown, fields with using YADCF and select options show all the options instead of only the selected option. You corrected this in a beta, but it seems to be back:

@Xcellere , if you reproduce it on the showcase page (second table) http://yadcf-showcase.appspot.com/DOM_Ajax_Multiple_1.10.html please do an open a new issue, if you can tell in what version it did work and since what version it has stopped please mention it too,,,

[vedmack]

replaced uncaught message with console.log (just in case)

@vedmack the test for undefined won't be hit for me. I'm seeing the json parameter return as null instead of undefined. My scenario is that the datatable is populated after the table is painted. The initial json return is empty so that the datatable has no rows.

Sending a PR changing === into == is shorter than the above post :) If not, I will commit it in the following days

fixed in 0.8.9.beta.18
