I had a trivial Durandal app working, paused to prototype a capability in an html page related only by the fact that it resides in the same folder, and then returned to the Durandal app only to find that while the shell is constructing the menu, views don't seem to load or at least render. The # url changes but that's it.
I've previously seen this when I had broken JS in a view or in shell.js, but I've tried stripping the routing table down to the home view which is basically static html with an empty view, and it's still happening.
The question is not so much "why are my app views showing blank" as "how does one go about troubleshooting this". There's no barfing, just a white silence. I'm not fond of guessing games and I can't believe a framework so well thought out lacks a strategy for troubleshooting.
Yes, I've seen the http://durandaljs.com/documentation/Debugging.html page. Debugging is switched on in my main.js but I don't know how to proceed from here.
So, where does one normally start when this happens? Some logging seems in order but I have no idea where to put it.
I marked the applicationHost div like so
<div id="applicationHost">
<div style="margin: 100px;">Hello, I haven't been replaced yet.</div>
</div>
and it vanishes right after shell calls router.activate()
OK, I found the specific problem, it was a bad binding in shell.html - the name of a binding target changed and the binding needs to be updated.
But the question of how to find this stuff remains. My app is trivially simple. "Inspect everything and hope you notice any problems" is not going to work on a complex app.
In the absence of any advice I'm starting to think that the only available strategy is to make only incremental changes with constant regression testing.

Ok this may be a vague question but I have an issue recognizing a webelement in one module (tab) but works completely fine in another tab. This is the same webelement. Everything seems to be same. It's the same form on the gui side with same properties and values.
Now this is another weird part, I can add one to the object repository but when I go to the other tab and try the same qtp becomes extremely slow. The + sign for adding it to the repository appears but when I click it, it gives me a message saying this object cannot be added to the repository.
The Web app uses extJS if that matters and this is a high level webelement that has a constant html id. I'm just puzzled as to why it works in one module but not the other.
There are also some subtabs where you can click on this form. Those work fine but when it comes to capturing this element the issue persists.
Any hypothesis as to why this is happening?
Okay it looks like it works when I took off the visible identification and just identifying it by the html id. I still don't get why taking the visible made a diff but it works.
I am building a site in Joomla (unfortunately) for a client. I have installed a template that uses Bootstrap as its basis, with some integration with Joomla, called H5BPTB. The problem I'm having is that when I visit the homepage on a small screen, and toggle the responsive navbar, it works fine, however after logging in, the navbar will open once, then close, but then no longer responds unless I refresh the page.
I read a few references elsewhere on stackoverflow to this being a problem with missing CSS transitions in the .collapse class in Bootstrap CSS. I checked and they are not missing. I also read another answer that suggested that it was a problem with some other Javascript overriding support.transition in the Bootstrap JS. I also can't find a reference to that in any other JS file. Is there anything else this could be?
Also I should add that the navbar works perfectly well in IE, but not in Firefox or Chrome.

I'd recommend just trying to update your Bootstrap files in the theme. They're both on version 2.1.1 and as far as I've seen looking around some people have had similar problems with earlier Bootstrap version.
The files you're looking to change are:
http://avantgardeinternational.eu/templates/h5bptb/css/bootstrap.min.css
http://avantgardeinternational.eu/templates/h5bptb/css/bootstrap-responsive.min.css
http://avantgardeinternational.eu/templates/h5bptb/js/libs/bootstrap/bootstrap.min.js
If that doesn't work, I'd try just looking around and making sure that some scripts aren't conflicting, that could just mean disabling all but the Bootstrap JS. Then seeing if it works fine.

Edit: Just attempted this, changing the CSS messed with the styles a bit, and it still didn't work. I don't think it loaded the JS into the page properly though, I'll try that now...
Edit 2: So after giving this a shot, I've concluded there is only one explanation now... I've observed the difference between the page when you're logged in and logged out. When you log in there are various other bits of JS that load into the page.
One of these must be overriding Bootstraps collapse methods, thus stopping it from working. There are a few extra scripts that load when you're logged in and some more styles. It might be working trying to remove these and then trying it again.
So I'm having a problem implementing a date_picker into a facebox. In a normal view, the date_picker is placed perfectly and works great. However, when the view is placed into a facebox, the calendar is placed outside of the facebox, and switching between months and years is messed up.
This image is how I would like it to look in the facebox.

However, this is how it looks like in the facebox.

Thanks for any help
P.S.- I'm using the Code Igniter Framework if that has anything to do with it.
The problem is most likely caused by the fact that facebox copies the html, thereby duplicating all element ids within. This is not standards compliant and causes incorrect binding of event listeners.
See Bishoy Labib's writeup.

The problem: In VS2010, I have a form with a broken design view. It's breaking on a couple of Atalasoft imageviewer controls.
The weirdness: Took me some time to figure this out, but if I go into the forms designer.vb file, and comment out everything regarding these controls, save, uncomment, and save again, the form design view loads perfect. NOTE: I'm not changing anything. Just commenting/uncommenting portions of the designer and saving.
The form design view continues to work fine until I do any of the following:
close the form design view and the designer.vb file and try to view again.
close the solution and reopen.
After doing either of these things, it's back to square one and I have to comment/uncomment/save to view the form designer again.
I'm on Win7, 64 bit. I have worked on this app in the past with no issue. The app builds and runs just fine. It's just a VS form design view issue, and I'm flummoxed.
I'd love to hear any thoughts on how I can solve this. If I can provide any more specific info, please let me know.
I've seen this happen rarely, when something odd gets into the designer file for a form and the designer can't figure out how to display things anymore. A third-party control being part of it could be indicative of some bug with that control's designer-related code.
One thing to try might be re-creating the form in question from scratch, and see if that fixes it. Perhaps something inadvertently got fubared. Also see if there is anything out there with others having designer problems with the same control(s) in question.
Sorry can't offer more direct help; maybe someone else has experienced something more closely related.
In Visual Studio, you can expand and collapse code without using regions, for example in a code-behind page you can collapse methods, etc... And in an ASPX page you can collapse tags, tags, etc...
It's useful when you have a long page and you want to focus your development on a specific part. What's cool about it too is that you can close the file and reopen it and the state of the expanded/collapsed blocks is saved exactly as you left it.
Except in one instance. That state is not saved for tags in ASPX pages, where it would be most useful.
I know there are some good plugins out there for VS but I couldn't find one that addresses this issue.
Has anybody got a solution?
Before you mention custom controls, they are not always convenient or feasible when trying to keep a page short and I don't consider this a solution to this problem.
Looks like this issue will stay unresolved at this time.
I opened a bug report on Microsoft Connect, if this issue is important to you please vote it up!
