Same here.

Not sure if it's a bug or something I'm doing wrong, but any help or pointers towards solving it would be appreciated

I think i found it.

The preview includes a file from share. This file seems to have changed name.
here is something i noted in another post

In default_preview_flash.php here are some lines that seem to be for an older version of alfresco.

$document->addScript($this->profile->share.'/yui/selector/selector-beta-min.jss');‍

is miss typed and should be ".js" at the end not ".jss" as seen below

 $document->addScript($this->profile->share.'/yui/selector/selector-beta-min.jss');‍

The following files dont exist. There is a new script and css in that folder but their is only one not two

    // Document Preview
    $document->addStylesheet($this->profile->share.'/components/preview/preview.css');
    $document->addScript($this->profile->share.'/components/preview/preview.js');

    $document->addStylesheet($this->profile->share.'/components/preview/full-preview.css');
    $document->addScript($this->profile->share.'/components/preview/full-preview.js');‍‍‍‍‍‍

finding the right replacement for these last four should hopefully fix the preview issue. they are in share under the http:\\<server><port>\share\components\preview folder

I have some more progress,

These are the required dependencies from share

$document->addStylesheet($this->profile->share.'/components/preview/web-preview.css');
$document->addScript($this->profile->share.'/components/preview/web-preview.js');
$document->addStylesheet($this->profile->share.'/components/preview/WebPreviewer.css');‍‍‍

Then the script initiation needs to be changed to

<script type="text/javascript">//<![CDATA[
new Alfresco.WebPreview("document-details").setOptions({…‍‍

the key change is new Alfresco.Preview needs to become "new Alfresco.WebPreview"

The instantiation is still off so it is not previewing anything but, the preview flash applet is still loading.

It would be great if someone knew how this call needed to be changed

<script type="text/javascript">//<![CDATA[
new Alfresco.WebPreview("document-details").setOptions({
   nodeRef: 'workspace://SpacesStore/<?php echo $this->file->uuid ?>',
   name: '<?php echo $this->file->name ?>',
   icon: '/components/images/generic-file-32.png',
   mimeType: '<?php echo $this->file->content_type ?>',
   previews: <?php echo json_encode($this->thumbnail->definitions) ?>
}).setMessages(
   {"label.currentFrame": "Page <b>{0}<\/b> of <b>{1}<\/b>", "button.next": "Next", "header.previewDocument": "Preview of {0}", "error.contentNotAVM2MovieClip": "The preview cannot be displayed since its not a AVM2 movie clip", "label.noFlash": "To view the preview please download the latest Flash Player from the<br\/> <a href=\"http:\/\/www.adobe.com\/go\/getflashplayer\">Adobe Flash Player Download Center<\/a>.", "label.jumpToPage": "Jump to page:", "label.noPreview": "This document can't be previewed.<br\/>Click <a href=\"{0}\">here<\/a> to download it.", "button.fullPreview": "Full Screen", "message.invalidFrame": "You must enter a frame between {0} and {1}", "error.server": "The preview cannot be displayed due to a server error", "button.previous": "Prev"}
      );
//]]></script>

came across this thread after figuring out the

the key change is new Alfresco.Preview needs to become "new Alfresco.WebPreview"

Now it's loading in Firefox (albeit not quite correctly) but not in IE. Has anybody made progress on this? Thanks

I just posted some code in the following thread
http://forums.alfresco.com/en/viewtopic.php?f=49&t=18426&p=62023#p62023

it should get the file page to a usable state. I still had to tweak the plugin's CSS file to get it to play friendly on my site (ul li and what not).

happy hunting.

Thanks again.

in share, in the web-preview.js file try playing with this section of code

               var so = new deconcept.SWFObject(Alfresco.constants.URL_CONTEXT + "/components/preview/WebPreviewer.swf","WebPreviewer", "100%", "670", "9.0.45");
               so.addVariable("fileName", this.options.name);
               so.addVariable("paging", previewCtx.paging);
               so.addVariable("url", escape(previewCtx.url));
               so.addVariable("jsCallback", "Alfresco.util.ComponentManager.find({id:'" + this.id + "'})[0].onWebPreviewerEvent");
               so.addParam("allowScriptAccess", "always");
               //so.addParam("allowScriptAccess", "sameDomain");
               so.addParam("allowFullScreen", "true");
               so.addParam("wmode", "transparent");                
               so.write(this.id + "-swfPlayer-div");  ‍‍‍‍‍‍‍‍‍‍

about my changes

My test lamp stack and test alfresco stack are two seperate boxes so i had to loosen the security on this. i bet this leaves me open for a cross site scripting so probably should change it back for production and have both servers on the same box.

so.addParam("allowScriptAccess", "always");

and

I had some character encoding issues while feeding my URLs to the flash. this should properly encode characters. the one that particularly gave me grief was the & character. MikeH (Alfresco Engineer) helped me find this one by suggesting i use fiddler as a proxy to see what the requests are and i found truncation issues between the JS and the Flash. This code change rectified it. That post is somewhere in this board

so.addVariable("url", escape(previewCtx.url));

aside from those two, every other change i made was to get indivigual user authentication working instead of a generic account.

one thing to do is to go to a document preview page in Share, view the source, then go to your document preview in joomla and also get the source. go line by line and make sure all your includes and variables correct.

the other code i posted should correct the includes and formatting. (or at least it looks great for me)

I think I might have figured this one out (at least for me anyway!). The problem seems to be with swftools. I've just compiled & installed the latest version (0.9.0) from http://www.swftools.org and the previews are now working fine. Something to do with the earlier versions not creating SWF files that are compatible with the alfresco interface. It was a bit fiddly to sort out but I'm probably doing it again tomorrow on my test machine so I'll try and document it this time…

ardesign: any pointers on what exactly you did, would be highly appreciated.
I'm running joomla & alfresco on an Intranet Windows 2003 server. I executed swftools-0.9.0.exe on this server, but can't see any differences..

Hello
I'm having the same problem. I made the changes on default_preview_flash.php the preview works only for txt files but not completely.
I have a first preview box but this one is completely white, and the preview box containing the real preview of my file is cut and totaly at the bottom left of my page.
Does somebody fix a problem like this one and help me?

thanx

Is there a final solution?

Thanks

Is this problem still not fixed yet? :evil:

I've encountered the same situation. Installed the joomla plugin for alfresco. Everything more or less works - bar the preview when looking through documents.

All I see is a black box where the document preview ought to be.

Previous searches and solutions offered by the people here have led to changing the black box into a smaller white file icon…

Can the techs working on this either tell us how to fix this or tell us how to turn the preview off altogether.
