Hi,

I used the example to develop a custom action, although I'm not sure I've followed it exactly I did get it working. If you could use a browser with proper debugging support (Safari, Google Chrome or Firefox with Firebug), you can tell where it's going wrong.

If you check the following and report back I'm sure I can give a more detailed answer:

Is the client side JavaScript file loaded?

Is a request being made when the action is clicked?

Are the correct parameters sent along with the request?

What is the response of the request being made?

If you use Firefox with Firebug you'll see the requests in the Firebug console and can see exactly what's being posted and returned.
Regards,

Michael

I have the same problem, I applied the example step by step but the custom action link does not do anything?
Any idea?

* Is the client side JavaScript file loaded?
    * Is a request being made when the action is clicked?
    * Are the correct parameters sent along with the request?
    * What is the response of the request being made?

1-yes client side js is loaded i see when i display the page source code
…
<script type="text/javascript" src="/share/components/documentlibrary/backup-action.js"></script>
…

2-there is no response(client ore server) being made when I clicked

3-here is my documentlist.get.config.xml   file

…
      <actionSet id="document">
         <action type="simple-link" id="onActionDownload" href="{downloadUrl}" label="actions.document.download" />
         <action type="action-link" id="onActionDetails" permission="edit" label="actions.document.edit-metadata" />
           …
   <action type="action-link" id="onActionBackup" permission="edit" label="actions.document.backup" />
      </actionSet>
…
‍‍‍‍‍‍‍‍‍

4. here is my backup-action.js

I'm sorry but you failed to correctly answer the question… I asked if it's being loaded, not if it's being referenced. If you use a modern browser you can check the resources section whether the file was loaded, otherwise you can paste the url into your address bar and see if you can reach the file (which doesn't assure it's being loaded, but at least means it's loadable). If you're not able to check any of these, add an alert statement to the script, if it fires then it's being loaded.

If no request is triggered, then I'd assume something is wrong in the client side script, so also check for javascript errors that get triggered when you try to invoke the action.

Michael

Re: Share 3.2 Custom Example - Not working

dark_rider — Sun, 16 May 2010 15:14:19 GMT

It loads, I see alerts and I use firefox, when i clicked the backup-action.js the source appears.

Sould I reinstall the alfresco and apply the steps again?
Thanks your help

Re: Share 3.2 Custom Example - Not working

mycroes — Sun, 16 May 2010 17:52:30 GMT

No, I'm guessing the guide is bugged, not your install. I followed the install myself and also ran into some issues, however it's been a while ago and I don't remember the exact issues I ran into… One thing that comes to mind is that the server side javascript file should be named backup-action.json.js. If you use firebug you can see the server response to the request being made by the client, which also contains errors if there are any. If you could look those up that might provide more useful information.

Michael

mikeh — Sun, 16 May 2010 18:22:56 GMT

It's likely because you're still using the pre-v3.2 "getRecord()" style when the wiki article states not to for v3.2 onwards. http://wiki.alfresco.com/wiki/Custom_Document_Library_Action#Action_JavaScript

Check the "Note for V3.2" section.

Thanks,
Mike

P.S. If you find a wiki article is "bugged" please find the time to correct it - that's what a wiki is all about!

I am trying to solve this problem last 2 days , I could not find the bug :?

Re: Share 3.2 Custom Example - Not working

mycroes — Mon, 17 May 2010 08:27:40 GMT

dark_Rider: a new set of questions:

Is the client side javascript being executed when you click the action? (Use firebug and breakpoints or something similar that verifies it's being executed)

Is a request being made to the server from the client side javascript? (Use firebug, keep console open and the request should show up when you click the link)

What is the response of the request? Is it a JSON encoded error? Does any message trigger in the client when the response is returned? Again, use firebug

Does the backup action create any files at all?

Up to now you haven't really provided enough information for anyone to figure out where the problem is. I think the missing .json in the filename contributed to the problem, however it doesn't seem to be the only issue…

Michael

http://wiki.alfresco.com/wiki/Custom_Document_Library_Action

I am also unable to get it working. A confusion on the tutorial is this:

To ensure both these files are served to the web browser, you need to add two lines (and a suitable comment is recommended) to the documentlist.get.head.html presentation template. Question: Is the document we edit documentlist.get.html.ftl or documentlist.get.head.ftl?

First there is no file like this: "documentlist.get.head.html". And yes, the question: which file should we edit?
If this is a tutorial for beginners, can someone please tell us what we should do?
I am trying many things but still it does not work. (I see the Backup icon, but when I click nothing happens.)
For now, I don't need to learn every detail about what is happening behind the scenes. I want to be able to write simple web scripts quickly first.

If this tutorial is updated, it will be really good for beginners. It is really painful to apply all the steps and see that it does not work. Any help is appreciated.

It says documentlist.get.head.ftl right where you quoted. You should add the two lines to that file. Also, it's a wiki, if you notice stuff like this please fix it (i.e. if it works for you, remove the question). If you can't get it working I'll be able to help (I have a working custom action), but it's been too long ago for me to remember everything I did back then…

If you can't get it working I'll be able to help (I have a working custom action), but it's been too long ago for me to remember everything I did back then…

I still can't get it working. Can you please share your working custom action?

And here is what I've done:

1) NOTE: I'm using community Version 3.2R, so I don't change "documentlist.get.html.ftl" file. (Tutorial says it is for pre 3.2)

2) documentlist.get.properties is updated.
icon image is put into images folder.
backup-action.css is created.

3) Here is the backup-action.js which is in folder: \tomcat\webapps\share\components\documentlibrary

/**

 * 
 * @namespace Alfresco
 * @class Alfresco.DocumentList

(function()

      });
   };
})();‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

4) Here is documentlist.get.head.ftl :
(Is there any problem with <link rel="…"> instead of <@link rel="…"> ?)

<#include "../component.head.inc">
<!– Document List –>
<@link rel="stylesheet" type="text/css" href="${page.url.context}/components/documentlibrary/documentlist.css" />
<@script type="text/javascript" src="${page.url.context}/components/documentlibrary/documentlist.js"></@script>
<!– Backup Action –>
<link rel="stylesheet" type="text/css" href="${page.url.context}/components/documentlibrary/backup-action.css" />
<script type="text/javascript" src="${page.url.context}/components/documentlibrary/backup-action.js"></script>
‍‍‍‍‍‍‍‍

5)From Alfresco's Data Dictionary, I create following content:
Under /org/alfresco/slingshot/documentlibrary/action

backup-action.post.desc.xml
backup-action.post.json.js
backup-action.post.json.ftl

These files are copy-pasted from the tutorial:
http://wiki.alfresco.com/wiki/Custom_Document_Library_Action

I can navigate to
http://localhost:8080/alfresco/service/script/org/alfresco/slingshot/documentlibrary/action/backup-action.post

and see the script properties successfuly.

I restart the server, create a site, upload a document. On the document library, hover the mouse on the document. On the right, I can see the "Backup" icon. Click on it. Nothing happens.

Any help is appreciated. I can support more info if needed.

Re: Share 3.2 Custom Example - Not working

And here are some parts from generated HTML code:

<!– Backup Action –>
<link rel="stylesheet" type="text/css" href="/share/components/documentlibrary/backup-action.css" />

<div class="onActionBackup"><a rel="" href="" class="action-link" title="Backup"><span>Backup</span></a></div>
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When user clicks on <div> of Backup action, how would the client-side Javascript be triggered if there was no problem?
Why does the javascript code not called here?
When I click on "Manage Aspects" action, an HTTP GET request is sent. But nothing happens for "Backup".

/var/lib/tomcat6/shared/classes/alfresco/web-extension/site-webscripts/org/alfresco/components/documentlibrary/actions-common.get.head.ftl, which has same contents as the original (in WEB-INF) with the following appended:
<@link rel="stylesheet" type="text/css" href="${page.url.context}/res/components/documentlibrary/download-pdf-action.css" />
<script type="text/javascript" src="${page.url.context}/res/components/documentlibrary/download-pdf-action.js"></script>‍‍
These refer to the client side files that are needed to invoke the action.

It's been a while since I created the action, otherwise I would detail my complete implementation on the wiki. However if someone gets stuck just tell me where and I'll see what I can do.
Regards,

Michael

The problem is the invocation of client-side Javascript. In my posts I tried to give information on my code. What can be the possible reason of the fact that clicking on "Backup" action does not trigger the Javascript? Any idea?

Please, please, please; use a javascript debugger. Just set a few breakpoints in the code to see what's executed. There's only two things you need to verify:

Verify that the prototype of Alfresco document list is extended with a function named to your action id,

Verify that the function is executed on click.

It should not be possible that only point 1 occurs and point 2 does not work. However, you need something like a javascript debugger to see if it worked or not…

One other way that you could at least verify the prototype is properly extended is by typing the following in the address bar after page load:

javascript:alert(Alfresco.DocumentList.prototype.onActionBackup);‍

This should show something like 'function …', if it says undefined you're client side javascript didn't extend the object.
