4.2.16 [T75] - Frontview web page unavailable. Resolved

[humbe]

I reported this in this thread viewtopic.php?f=51&t=51400, but as this issue is totally unrelated to the original issue in that ticket, I'll create a separate thread.

I cannot access frontview from a windows PC. I get a frontview page where the boxes are draw, and the 3 top right buttons show (refresh, help, logout), but the content part is empty, the menu on the left doesn't exist and the lower left buttons have no text. This seems to be because of javascript errors.

I have tried Internet Explorer 8 and 9.
I have tried Mozilla Firefox 3.6.13 and 3.6.15.

From my work PC at work I can access frontview fine from an Ubuntu linux box running Mozilla Firefox. There, no javascript errors are reported in the error console.

This is the javasript error I get in Firefox 3.6.15. This seems to stop javascript processing so frontview have no content.

Error: sec_wizard is null
Source File: https://nas2/js/dialog.js
Line: 1780

And here is part of the dialog.js file:

 loadWizard: function(xmlDocument) {
      var wizard = xmlDocument.getElementsByTagName('wizard').item(0);
      var temp;
      if (NN.ProductMode == 'home' && NN.Security == 'share') {
        alert('ERROR_INVALID_SECURITY_MODE');
        NN.Security = 'user';
      }
      var pd_wizard = wizard.getElementsByTagName(NN.ProductMode).item(0);
      var sec_wizard = pd_wizard.getElementsByTagName(NN.Security).item(0);
      var ni = sec_wizard.getElementsByTagName('node'); <--- FAILS ON THIS LINE.

      var node_array = new Array();
      for (var ix = 0; ix < ni.length; ix++) {
        var local_node = new node();

        var include = NX.get_data_from_xml(ni[ix], 'include');
				if ( include && !eval(include) ) 

And here is the whole error console output when trying to load frontview:

I've tried to find the dialog.js file on the drive so I could alter the code to see if I could get something to work, but failed to find it.

I guess you have cleared your Browser-cache.

wich version is your JRE?

[humbe]

After I reinstalled T75, frontview started failing with the same error at work too.. Maybe it worked at work due to some old browser cache. Tried to clear entire browser cache now, but to no avail.

At work I'm using java 6.. 6.20dlj-0ubuntu1.8.04.1
I guess that means java 6.20.

But javascript aint java. Client side javascript is just implemented in the browsers. But I guess it may be code trying to access java that can fail some way due to java version if that is what you were thinking.

Java JRE does not affect FrontView.

Boot in Tech Support mode, give me the five digit ID from LCD/RAIDar.

With the system powered off, hold in the Reset button on the back while turning it on. When 'Boot Menu' appears on the LCD, release the Reset button, and use the Backup button to navigate the menu. When you see 'Tech Support' on the LCD, press and release the Reset button once more. After a minute or so, it will give you the ID number.

Booted in tech support as requested and sent 5 digit number to chirpa and yoh-dah, that requested it in pm earlier today. Note that there's a restrictive firewall outside of my NAS box. If this is screwing up for you connecting to it, let me know some details on how you're trying to connect.

[chirpa]

It should be rebooting, let me know if it loads up.

[humbe]

Whee.. It's up and running, and frontview is working again.. Thanks a lot

What did you do to fix it? Anything I should keep in mind to not get back into the same state again?

[chirpa]

You have an NV+ in your forum profile. Did you by chance do a config backup on the NV+, and restore that on the Ultra? That would have caused the issue I saw, invalid security mode. The NV+ supported User,Share,Domain. Share has been phased out, no longer used. The Ultra should only have User mode, but somehow it had it set to Share.

[humbe]

I can't remember having tried to save and restore settings from frontview anyways. I've been trying to set Ultra 6+ up as I want it, and have probably been looking at my NV+ config while doing so.. Though, I can't remember having touched anything but minidlna.conf and samba config. But maybe I changed something trying to get samba authentication to work.

[chirpa]

Well the situation you ran into won't happen in future firmwares, they will auto-fix themselves.

I have the same same issue and am very relieved to find a post that claimed to have been resolved, especially after going through hundreds of posts.

We are using the ReadyNAS 2100 and have the same FrontView problem with limited page loading and the javascript error after it is "done." We haven't copied/restored any configs from another device but the issue persists, even after reboots. The only change to the config we made besides the basic IP addresses and iSCSI target setups is a firmware change to 4.2.12 from what it shipped with.

How can we go about correcting this problem?
