[Paraview] No rendering in ParaviewWeb with javascript

Thu Oct 25 16:48:08 EDT 2012

Thanks Seb,

I realized that i was running my html page  under Apache but it was not properly configured to talk to paraviweWeb which is under. tomcat. I Fixed that and i worked fine. Thanks

My goal is to add  this code under a Mediawiki Page and run it on a button click BUT when i do that i get "uncaught exception: get_module() takes no arguments (2 given). Paraview.js line 231"

I see one deference in the way internal paraviewWeb POST calls are made.

1. When running outside Mediawiki (This Works) : 
  {id:3,method:"VisualizationsManager.invoke",params:["87095ed9081c5fc32c76f43105d74c32-28", "{\"id\":1,\"method\":\"get_module\",\"params\":[]}"]}

2. Within MW ( This gives above exception)
{id:3,method:"VisualizationsManager.invoke",params:["87095ed9081c5fc32c76f43105d74c32-27", "{\"id\":1,\"method\":\"get_module\",\"params\":\"[]\"}"]}

the difference is  how empty param are specified in both the POST requests.   [] Vs. \"[]\"

Both are made internally by ParaViewWeb, so do you think i can control this in my javascript ( actually jQuery) code ?? OR on ParaviewWeb code/config side ??

Thanks

Try to move the script section between </table> and </body> . Moreover does the other applications let you properly see 3d content?
