Unknown runtime error in Graphical View editor
- 
 After placing a component into a graphical view and clicking on the computer monitor icon to edit the graphical renderer, I get a "Unknown runtime error" dialog from the browser, and I'm unable to edit the renderer. I'm running Mango 1.9.0, Tomcat 6.0.20, and IE7.

 Just use Mozila Firefox 3.6

 I get the "Unknown runtime error" when editing the graphical renderer, mango 1.9.0, Tomcat 6.0.20, IE8, everything else in Mango is sweet. Regards

 Is there any output in the Tomcat console? 
- 
 Also, IE8 works for me. Is there any specific thing that reliably recreates the issue?

 Check this out: http://www.gljakal.com/blog/2006/02/19/unknown-runtime-error-in-internet-explorer/. Can you describe the components that are in your view?

 I have the default Mango Graphical View Page, with a background image. It is when I mouse click on the "graphical rendering of a component" button, the runtime error pops up - see image, have found a work around :D as ftomiBR said just use firefox to do the edit it then can be viewed in IE8. 
 Also did a fresh install on another PC and get the same runtime error, IE8 is just being fussy.Solved for now Attachment: download link

 Ok. Thanks for the description. I was able to recreate it fairly easily. I'll look into a fix.

 I have a fix. It will be in the next release.
