I am using GWT and need history and using:
<iframe src="javascript:''" id="__gwt_historyFrame" style="width:0;height:0;border:0"></iframe>
But can I change __gwt_historyFrame to any other name AAAAA? Is it possible like below:
<iframe src="javascript:''" id="AAAAA" style="width:0;height:0;border:0"></iframe>
Here is some good documentation on the GWT History: http://developerlife.com/tutorials/?p=232
and Google's documentation on the host page: http://www.gwtapps.com/doc/html/com.google.gwt.doc.DeveloperGuide.Fundamentals.HostPage.html
Giving the following code example:
<!-- Include a history iframe to enable full GWT history support -->
<!-- (the id must be exactly as shown) -->
<iframe src="javascript:''" id="__gwt_historyFrame" style="width:0;height:0;border:0"></iframe>
Sounds like the iframe must have id="__gwt_historyFrame" and cannot be changed to "AAAAA" or anything else.
You would have to build your own version of GWT with a custom implementation of HistoryImplFrame. And as other replies have stated, there really isn't a good reason to do this.
If you use the MVP architecture presented by Google, you won't need to change it in order to handle history. I don't see why you would want to change it but this look like a GWT Defined variable that you shouldn't change.

I am trying to understand what kind of web applications Apache Wicket is suitable for, and it seems to be page based from what I have seen. How can it be used to make single page web apps as well?
At our company we have 3 SPA built on Wicket. They all work :) Basiclly our structure is:
<html>
<head>
</head>
<body>
<div wicket;id="menu">
<!-- navi links -->
</div>
<div wicket:id="main">
</div>
</body>
</html>
And we replace the main panel and it's inside panels effectivly getting an SPA.
Ajax support in Wicket 6 is very good.
Yes, its basically for page based webapps. So, it can also be used easily form single page web app.
I suggest just reading this short example of Hello world
After that, you can easily edit your equivalent of HelloWorld.html and HelloWorld.java to make really easy HTML in Java.
I am trying to integrate facebook comments into my website (I tried to do it several months ago but there didn't seem much support about and I couldn't fathom it). The comments are showing and I managed to get the comment to show on my facebook wall under the individual post/item they were meant for but unfortunately it is posting the same comment under every post. You can see the box working here: http://www.roomfor5.co.uk/item/6726
The website is php based and the code I am using is: " title="" url="" width="600" publish="true" >
I have also used this code without success: " width="600" publish="true" >
I know it's something to do with the xid attribute but I am stumped as to why it is duplicating:(
Hi when looking at the view source of your page I see this:
<fb:comments
xid="http://www.roomfor5.co.uk-<?=str_replace('/','-',$_SERVER['REQUEST_URI']);?>"
num_posts="2"
width="600"
publish="true" >
</fb:comments>
So the fb:comments tag is not getting rendered out fully.
Also on the rendered page, it says you haven't specified the url. while there is a malformed xid= attribute, you really should have a url= attribute. See https://developers.facebook.com/docs/reference/plugins/comments/
Warning: this comments plugin is operating in
compatibility mode, but has no posts yet.
Consider specifying an explicit 'href' as
suggested in the comments plugin documentation
to take advantage of all plugin features.
EDIT:
For http://www.roomfor5.co.uk/item/6726, you have
<div
class="fb-comments"
data-href="http://www.roomfor5.co.uk"
data-num-posts="5"
data-width="600">
</div>
The data-href attribute should be http://www.roomfor5.co.uk/item/6726 not http://www.roomfor5.co.uk
If you click 'View source' you'll see the rendered HTML:
<fb:comments xid="http://www.roomfor5.co.uk-<?=str_replace('/','-',$_SERVER['REQUEST_URI']);?>" num_posts="2" width="600" publish="true" >
It looks like you're trying to specify a unique xid for the page but the server-side script is behaving like plain text.
I'm working on using the fb registration plugin on my sites. Sometimes a site doesn't support iframes. Is there another version of this script below that works without iframes or is there a workaround?
<iframe src="https://www.facebook.com/plugins/registration.php?
client_id=113869198637480&
redirect_uri=https%3A%2F%2Fdevelopers.facebook.com%2Ftools%2Fecho%2F&
fields=name,birthday,gender,location,email"
scrolling="auto"
frameborder="no"
style="border:none"
allowTransparency="true"
width="100%"
height="330">
</iframe>
thanks for any help
I don't understand what you mean by the idea that a site 'doesn't support iframes', but to answer your question, the Registration plugin is only available as an iFrame and i'm not aware of any other way to use it.
There's no reason you couldn't implement the Registration plugin's functionality yourself using the regular APIs if you needed to for some reason. The registration plugin just optimises a particular use-case ('sign up for a site with the possibility of using Facebook account information') and makes it faster to implement.
Yes there is. You can use the XFBML version of the plugin. This allows you to not only do what you are asking but to validate custom fields. This is what I choose to use on my application. However, I am not sure if fb is going to deprecate this or not come Jan 1st. Considering there is no replacement, it would be a little messed up if they did. For information on how to use and implement this see this link:

Is it possible to implement the Facebook like and share functionality for "liking" the comments of other users on a website? Does every comment has to have a permalink?
I have asked the question on Facebook developers forum, and they have come back to me with this response. Basically, the functionality that is required is not available.
http://forum.developers.facebook.net/viewtopic.php?pid=316205#p316205
Intro:
You will need individual like buttons for every comment, and as #Fnatte says you can then reference them to the comment by giving it an ID like #com1,#com2etc...
The best way to achieve this is through a for loop (I imagine you are pulling from a DB) that will iterate through and add the relevant code for the like button and implement the URL based on the comment it is pulling,
The Code:
You have 2 options, <iframe>:
<iframe src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fexample.com%2Fpage%2Fto%2Flike&layout=button_count&show_faces=false&width=90&action=like&font=segoe+ui&colorscheme=dark&height=21" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:90px; height:21px;" allowTransparency="true"></iframe>
This is VERY slow, especially if you have a lot of comments loading at the same time, it does mean you don't need to import their JS library though,
Then there is the FB JS SDK:
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script><fb:like href="http://example.com" layout="button_count" show_faces="false" width="90" font="segoe ui" colorscheme="dark"></fb:like>
This I would argue is a more eficcient way of doing things, but it does require a bit more time and effort - but will be well worth it.
The script of course can be imported only once in the head and then used multiple times throughout the page (perfect for what you need).
The URL to like is based on both the URL in the address bar and the ID that you have assigned to the code (e.g. #comment1) so the URL you are liking looks like this: http://mypage.com/page#comment1

Good luck and I hope this helps!

updated, hope this help
I have never done it myself but you should probably check out http://developers.facebook.com/docs/guides/web#plugins.
It looks like you would need a unique link for each comment.
You could try including a fragment identifier in every URL like:
http://domain.com/article1#comment1
http://domain.com/article1#comment2
Facebook has rolled out a new version of the comments plugin which supports advanced functionality such as "liking" and replying to other comments. In addition, replies to a comment made on Facebook.com are now pushed back to the comments plugin (hosted on another site.)
How to enable:
Add the migrated attribute:
<fb:comments xid="YOUR_XID" migrated="1"></fb:comments>
OR use the href attribute instead of xid for future comments boxes
<fb:comments href="YOUR_CANONICAL_URL"></fb:comments>
References:
New <fb:comments>
Legacy <fb:comments>
According to the Facebook developer roadmap, it will soon be possible to put iframes inside page tabs but it's not yet available. I came across this Store Locator on Coach page which uses an iframe to display a Google map inside a tab :
http://www.facebook.com/Coach?v=app_168904438199&ref=ts
Looking at the source code, I see the map really is inside an iframe. How is this possible?
in STATIC FBML pages you CAN'T USE IFRAMES - no matter what FBML code you put in there, facebook have specifically made the code not work in in business page/tab static fbml pages - my guess is so they can prevent people setting up Amazon stores or other content that uses IFrame (spammers and spyware often use iframes) - the updates are in their 2010 wiki - so it's probabley also a security thing.
I frames can still be used on developers canvas pages apparently but the customer has to click on an image for it to activate rather than the iframe automatically loading - again this is probably a security issue to prevent driveby downloads - where zwinky and similar toolbars are forced onto people computers in the background via iframes without their knowledge.
However some say it does work although you need a user to click on it before it works. if you can live with that then go for it.
<a onClick="outside_location.setInnerFBML(location_two);" style="cursor: pointer;"><center>→our website</center></a><div id="outside_location"> <fb:iframe width="730" height="400" frameborder="0" src="http://www.fborder.com/" /> </div>
<fb:js-string var="location_two"> <fb:iframe width="730" height="600" frameborder='0' src='http://www.fborder.com/' /> </fb:js-string> <script type="text/javascript" charset="utf-8"> var outside_location = document.getElementById('outside_location'); </script>
check out this post. people have got it to work. and some say it wont work for the obvious reasons. such as security and so on. but give it a go regardless.
