Submit fails under the local host with no active remote internet connection.

[irwincohen]

I have a workspace named “test” with a database named “test” with no tables and only one page named “test.a5w”. That page has only one UX component named “test.a5cmp”. That component has only one control, a submit button. The enable condition for that control is cleared so the submit button is always active. The javascript for the submit button is standard as: {dialog.object}.submit(); The afterafterDialogValidate event has only one statement: file.append_line("c:\a5out\out1.txt", "worked"). The local host is enabled and the component submit button works in working preview. The file "c:\a5out\out1.txt” is created and written.
The page and component is then published to a local webroot sub folder named “test” and opened in a browser with the url “http://localhost/test/test.a5w” and again the submit button works as normal, the file "c:\a5out\out1.txt” is created and written.
However, in addition to the local host, I also have an active normal wireless internet connection. But when I put my computer in “Airplane” mode, the submit button no longer works. It is still enabled but the afterafterDialogValidate event never fires and the file is not written. The same is true if the computer is not in “Airplane” mode but the active internet connection is disconnected or disabled but the local host is still active.
So it seems that the submit button javascript fails when the only active server is the local host. It only works if there is an active remote connection in addition to the local host.
Other buttons using javascript functions like an alert seem to work fine with the local host, with or without a remote connection. Only the submit button fails.
I have tested this using chrome, edge and IE11 all in widows 10.
Has anyone else noticed this or can explain this. It is not a serious problem but I am curious. This may be relevant to a recent post at

Re: Submit fails under the local host with no active remote internet connection.

This is an OS or browser issue preventing network access and unfortunately there is not anything Alpha can do to work around it in any way.

There is an (older) Chrome bug regarding this at https://bugs.chromium.org/p/chromium...detail?id=8910

There are also indications that you may need to reconfigure your DNS service on the local system at https://forums.iis.net/t/1174353.aspx

Re: Submit fails under the local host with no active remote internet connection.

Irwin, there are a lot of details in you question, so maybe I'm overlooking something, but to me this sounds like the issue where the alpha ajax library refuses to communicate with the server if it "thinks" the browser has no Internet connection. And as you pointed out, this is a problem when working offline, but with your own local server. As far as I know, the ajax library funnels all calls to figure out if it is online or offline through a common function which just checks the value of "navigator.online", which is built-in to the browser. However, the common function can be set to ignore "navigator.online" and mimic being offline or online as determined by you. To override the function, go to the OnInitializeBegin client-side js event for your UX and enter one of the JS commands:

this._setSimulatedOnlineStatus('on');
this._setSimulatedOnlineStatus('off');
this._setSimulatedOnlineStatus('');

The first two are self-explanatory. The last one disables the simulated mode and causes the common function to revert back to its default behavior.

OK Rich that worked. I used this._setSimulatedOnlineStatus('on'); in the OnInitializeBegin client-side js event and that solved the problem and now the submit button works when I am using a local host and no external online connection.
Thanks,
