Hi,

I came across a very strange issue, When I try to get the data from the Marvin Applet Editor using the getMol() method. The browser Java console throws the below error. This issue is faced only in some systems. So its very hard to find the actual reason for the issue. This is one of the critical issue we are facing due to which development is paused. Does it have anything to do with Java update?. Pls respond ASAP.

Uncaught Error : Error calling method on NPObject

Hello,

Could you provide us the html code which you use to deploy the applet? Preferably the method calls you use in it, and references to contentDocument would help.

Hi there,

Does this problem occur while using mozilla firefox web broswer ? Does the same thing happens when using other browsers ? Also, which java versions were used when the problem occured ?

Lastly, could it be related to this issue : https://www.chemaxon.com/forum/ftopic12000.html ?
