About the strange tag behavior in OpenLaszlo
Hi Sebastian,
I’m currently trying to implement drawing iframe on the whiteboard, and
just found that OpenLaszlo <html> tag does not work properly for me. If I
add something like
“<html *bgcolor*="blue" *src*="
http://localhost:5080/openmeetings/docs/demo.html" x="15" y="45"
width="500" height="700"/>”
in any OpenMeetings static view, I see blue rectangle instead of the
docs/demo.html content.
Please note that
http://www.openlaszlo.org/lps4.9/laszlo-explorer/editor.jsp?src=docs/reference/programs/Extensions-$167.lzxexample
works well for the htmls from localhost (if I have OM running
there), and does not work for the external urls.
It seems like <html> tag does not work in solo mode at all, and works with
some security limitations otherwise. OpenLazslo API reads nothing about
this.
I’ve filed a bug against openLaszlo, but have not received any answer – the
project has died.
I’ve googled this and found your old correspondence with OpenLaszlo support
where you wrote that similar things worked for you, for example see:
http://www.openlaszlo.org/pipermail/laszlo-user/2010-April/008143.html
So my question is – Am I doing something wrong? Or probably this worked in
some previous OpenLaszlo versions and stopped to work in the latest ones?
It’s not good that it’s impossible to see external iframes from OpenLaszlo,
however for now at least having html from localhost would be OK for me.
Is there any other alternatives to resolve this problem? Could you please
advice?
Thank you,
Irina.

Hi Sebastian,
Thank you very much for the answer!
I'll think about this further.
Best regards,

Hallo Irina,
unfortunately the html tag never really worked accross all browsers.
I had it once running for OpenMeetings but removed it again since it did
not work for IE8 on Windows7 (but fine everywhere else).
Basically the issue of this thing is not OpenLaszlo, its a matter of the
embed code and JavaScript code that includes the SWF.
What you do is actually adding an overlay over the SWF.
So my best advice would be:
Try to look into the basic html file that includes the SWF and try to add
some static HTML overlay object into that file.
If that works, try to make this overlay object "dynamic" by adding some
JavaScript methods that create and remove it.
And then you only need to trigger those JavaScript methods from OpenLaszlo.
Calling the JavaScript from SWF is easy.
That might sound more complex as "repairing" the HTML tag in OpenLaszlo,
but the issue is really that without debugging OpenLaszlo and compiling
OpenLaszlo from source its not possible to resolve.
