Display totally destroyed

[Thierry58]

Hello
I would like to let my users read .odt documents.
I was told WebODF was a great solution.
But I tried the editor, online version as well as using the JS, with no good result.

Some real simple .odt are more or less displayed (some margins and logo missing), while at least 3/4 of my tests showed a document totally broken on screen

(half is not displayed at all, the rest partially resides in narrow columns to the left while nothing is at the right side, etc...).
In order to demonstrate the huge difference between document opened in LibreOffice and same doc opened in the editor.

So I was wondering if this project is really working or abandonned "as is".
I read comments in this section where some people are asking same kind of question.

Is WebODF dead ?
If it is, would someone know of any alternative to have .odt docs displayed in a web page ?
Even better if edition of the document is possible.

I will try the CK editor although I am not sure it has support for ODF fomat.
Thank you.
