Hi guys,

does the email module work just like a webmail interface for the entire email account, or can I use a single email account with multiple “projects” and then setup contacts for each project which is then filtered against the email account, so say I have 700 emails in my account inbox, but only 50 of them are from clients in project “barcelona-football-club” will it show all 700? including emails from other clients in other projects setup in feng office, or will it only show the 50 emails relevent to this project I am currently viewing.

because if it shows all 700, then I can't use it obviously, but if you needed an idea to develop this further, I think that what I just suggested would be an excellant feature for future versions, the ability to share a single email account with multiple projects, all filtering against the contact list of each project would be a big improvement in my eyes.

thanks, I hope you can reply to my question

I am the CIO of a small contracting firm. I'm getting ready to implement Feng Office in my organization to manage clients, as well as many of our business processes. I was wondering if it was possible to get a copy of the wiki or manual emailed to me. If a manual does not exist yet, I would like a printer-friendly copy of the wiki so that I may provide training to my employees.

Thank you,

You can download our wiki or convert it into a PDF document as you would do with any other website. Unfortunatley there is no printer-friendly version of the wiki we could send you.

Hendry Chandra, 2010-02-24 06:58

dear admin ,

plase send me the manual technical documentation please

Quisiera saber como crear una carpeta.

La verdad estoy probando y no lo logro.

Espero su respuesta



Francisco Ponce de León, 2010-10-20 16:11

Hola Andrea, a qué te refieres por carpeta en sí? Si es a lo que convencionalmente se le llama carpeta en un sistema operativo, es porque no existe dicha opción en Feng Office. Sino que lo que utilizamos son grupos de trabajo (workspaces) cuyo rol se asemeja en parte al de una carpeta pero tiene muchas más opciones de permisos entre otras cosas. Saludos

Loaded system fine.. Been working for a number of hours really well until…

this happened: missing lang.js everywhere???

Anyideas on what it means

Stig, 2010-10-27 19:41

I installed Feng Office today, and I also get this error :S It's standing like: Missing lang.js: overview - Missing lang.js: messages - Missing lang.js email tab, etc. Please help Richard and me!

Francisco Ponce de León, 2010-10-29 14:15

Which version of Feng Office have you installed? If you installed the 1.7.1 you may experience that problem

Stig, 2010-10-29 14:39

I don't know why, but it worked when I changed web host. (from 000webhost to x10Hosting) :)

Peter, 2011-02-01 04:47

The Missing lang.js problem persists in 1.7.3. is there a ticket I can follow until the problem is resolved? I ask because the same error message is reported for nearly every release from 1.3 onwards.

Peter, 2011-02-01 07:51

The lang.js file was added with the domain in the url twice. I fixed the problem by replacing: add_javascript_to_page(with_slash(ROOT_URL) . 'language/' . Localization::instance()→getLocale() . ”/lang.js”);

with: add_javascript_to_page('/language/' . Localization::instance()→getLocale() . ”/lang.js”);

Thom Maas, 2011-02-26 08:08

What's the name of the file, where the domain is set? Because I can't find the line “add_javascript_to_page…”.

Thom Maas, 2011-02-26 09:54

Here is a how to:

Feng Office has huge potential. It is exceptionally well conceived and executed. But, like any meaningful project emerging from adolescence, the technical details are a bit hidden. No matter. I don't mind asking questions.

I am trying to determine the technical pros and cons of using File System for File Storage versus Database. My first inclination was that files might be retained in their native format in File System and that that would provide some comfort - users could inspect the directory and even fetch documents directly if necessary.

Now I see that the directory structure is difficult to decipher (not a bad thing, just a difficult thing) and I know that files in uploads do not retain their native file form. Fair enough. But, honestly, I'm not at all sure what is actually placed beneath uploads. I uploaded a large (4+MB image) and saw no new directories under uploads result; whereas if I fetch new mail I see plenty.

I went to the mySQL database to see what I might learn there.

I found some entries in the DB in the og_project_files table referencing the five actual files that had been uploaded, and complimentary records in og_project_file_revisions, and in og_project_file_revisions noted with interest a repository_id, for example, of 2ef292272ce1f244ef08bca91275b5b7df087507, similar in structure to what I found in various actual uploads directories. But, a find for that particular directory failed to produce a hit.

While looking at og_file_repo_attributes I found the id matching the example repository_id. While I could find other og_file_repo_attributes ids in the uploads directory, none of the og_project_file_revisions repository_ids were found.

I have spent several hours searching for answers. Maybe you might help me?

1) I saw a slight reference on a page indicating that mySQL was the preferred file repository. Please confirm. We are still early enough in review to changed the file storage mechanism.

2) Why couldn't I find actual uploaded files in the uploads directory; but rather, seemed only to find directories with keys matching the emails and perhaps a few other objects (avitars for example)? Where went the large 4MB image I uploaded that matched the key referred to earlier?

3) Our actual business case will necessarily result in tens of thousands of engineering documents, some quite large. Since those uploads appear to be separated from other files in uploads (somehow, although frankly, it doesn't feel right), if the File Storage is mySQL will it be able to handle large volumes of large files as BLOBS or does it put them outside of the database table?

4) We are likely to look at contributions in either monetary form or of code if and when we adopt. Need some help in support of that objective.

Thank you in advance,

Francisco Ponce de León, 2011-02-16 15:25

You have already been answered this in forum, and I have noticed you have already checked the reply

Fanta, 2011-02-02 14:06


I've intalled fengoffice today and I'm testing it.

Please is there a plugin to link fengoffice to java for user management?

Thank you


Francisco Ponce de León, 2011-02-16 15:26

I am afraid that right now Feng Office does not count with such feature. Kind regards

Shellway Ho, 2011-02-14 23:51

Hi FO team,

I've been using FO about two year long, and I like it very much.

But here has not much developers' documentation, I feel so hard to extend FO.

Can we have more FO API documentation this year?

According to the blog post about 2011 todo list, it seems that you guys will do this and make FO a very extensible platform. I am looking forward to this.

Hope FO be better and the best。

Best regards

Shellway the CN guy

Francisco Ponce de León, 2011-02-16 15:37

Hi Shellway,

We certainly look forward to improve many aspects of Feng Office, but this does take time.. so I am afraid what you are asking for is not ready yet and will not be that soon.

Best regards,


hudson, 2011-04-25 19:57

Having an API without documentation is the same thing as having no API.

I think is far more honest to say you have no API, and people should just read the source code.

But hey, it takes a lot of time, people must go to the beach and watch the vuelta ciclista.


Francisco Ponce de León, 2011-04-26 11:08

Actually we do work a lot, but unfortunately as you mention, lots of things take a lot of time, which we do not count with.

But hey, it is an open source application which you may use with no cost at all, where anyone willing to help documenting or developing is more than welcomed.. so if you would like to help, please go ahead.


Hudson, 2011-04-26 23:48

Alrighty, can you please send me a reference which source files and entry points are the main API components?

I'll handle the docs.

Francisco Ponce de León, 2011-05-06 12:00

Hello Hudson,

First of all, sorry for the late reply! Please get in touch with for further information about the API components
