Senthil K Ponnusamy - 2018-10-17

Page loads fine in browser. As it's failing to load javascript, I don't get the javascript generated content. Thanks

For analyzing this i need more details

usually there is a inner exception - please post this also (or even better the whole log output

i guess you are doing a simple getPage(url) call, i need the url also to debug this

When I set not to throw above javascript error ( webClient.getOptions().setThrowExceptionOnScriptError(false);) then I get the following as page xml, which doesn't have all fields as java script failed to execute.

@RBRi, Please let me know if you need any further information on this. Thanks

  Maybe yes;
  
  I need the real cause of the problem. Can you please set a JavaScriptErrorListener for your client and implement the method scriptException() in your error listener. Then debug or make sure to dump the whole throwable parameter including all cases.
  
  Background: In Rhino all the js support is implemented in Java methods, and these methods are called via reflection. In your case one of the java methods throws an error (e.g NPE) but this error is wrapped as cause along the way up to rhino. I need this cause to figure out what is going on.

Sorry too many open threads....

Cannot modify readonly property: constructor

This seems to be more or less teh same problem as https://sourceforge.net/p/htmlunit/bugs/1897/. Because we are using Rhino and there are some problems with the support of more modern js i guess there will be not that much progress during the next weeks.
If you like to help it will be great if you can check if the problem is the same as in the issue mentioned above. And of course any PullRequests for Rhino and or HtmlUnit are welcome.

Yeah, I checked it before and it looks like the same issue.
