Dear OpenMeetings Developers,
We created a new method which then calls the action command for our new
sub-menu items, and from there we are able to load and display the
desired file. If someone has a need, we will be happy to share the code.
Sincerely,

Dear OpenMeetings Developers,
We would like to load a one-page PDF file to whiteboard by clicking on
a sub-menu link in menu dropdown. We are able to upload and display
the PDF file on whiteboard through File Explorer, thereby meaning
ImageMagick, Ghostscript and OpenOffice are properly installed and the
configuration path in OM 3.0.7 is correct. However, when we click on
the menu link to the PDF file, it gives a DELETED (large) picture. We
have placed the SWF created from the PDF file
inopenmeetings/dist/red5/webapps/<OMinstance>/upload, ../files
directories.
We would appreciate any vectors to solve this issue. Below are the
details.
------------
DETAILS
------------
We are able to successfully use the following call from within the
Onclick Handler of a Menu Button of conferenceMenuBar:
by replacing the "fileHash" parameters with our SWF filename placed in
"<OM_HOME>/dist/red5/webapps/<OMinstance>/upload/files" directory":
canvas._drawarea.parent.parent.clearAreaAndAddImage(this.generateFileLink(file1.swf),0,0,
canvas.getUrl() +'DownloadHandler',
"file1.swf","videoconf1","/","files",hib.conferencedomain);
However the same code called from within the "onclick" OR "command"
handler of a Sub-menu command, it only displays the "DELETED" image or
"Image Deleted" picture.
1. We put this code and call directly in command action code.
2. We created a new method with this code (method upchart) in
"mainAttributes.lzx", and call it from command action code.
3. We added this "upchart" method inside a clone of
conferencDropDownMenuItem, and called it from its "onclick" handler.
We have extracted the image loading part of the steps and put it into
a method, which is then called from the onclick handler of a clone of
<conferencDropDownMenuItem>, like "<abcDropDownMenuItem>"
(we can't put this method in the original, as that would affect all
the existing submenu items behaviour).
<handler name="onclick">
if (!this.enabled) {
return;
}
this.upchart('file1.swf' );
parent.parent.close();
</handler>
And the method definition of this method is also included within
the class definition of <abcDropDownMenuItem>:
<method name="upchart" args="upfilename">
<![CDATA[
var fileLink = canvas.getUrl()+'DownloadHandler?' +
'fileName='+ upfilename +
'&moduleName='+ "videoconf1" +
'&parentPath='+ '/' +
'&room_id=files' +
'&sid='+canvas.sessionId;
var secondid=0;
var isOwner=0;
var servletName='file.upload';
var
parentFolderId="/usr/local/openmeetings/dist/red5/webapps/<OMinstance>/upload";
var uploadurl = canvas.getUrl() + servletName +'?' +
'moduleName='+ "videoconf1" +
'&publicSID='+canvas.publicSID +
'&filename='+ upfilename +
'&parentFolderId='+parentFolderId +
'&room_id='+hib.currentroomid +
'&secondid='+secondid +
'&isOwner='+isOwner +
'&sid='+canvas.sessionId;
if ($debug) Debug.write("uploadurl: ",uploadurl);
canvas._drawarea.parent.parent.clearAreaAndAddImage(fileLink,0,0,
canvas.getUrl() +'DownloadHandler',
upfilename,"videoconf1",parentFolderId,"files",hib.conferencedomain);
]]>
</method>

In the last line, if we replace "files" parameter with "", then it
should take the file from "upload" folder. It is not taking it either
way. In the Menu Button case, both scenarios were succeeding.

I guess filehash is sort of MD5 hash on filename (maybe + some
additional data, like date) This need to be done on server to match DB
