ScriptException: Exception invoking getScreenX #173
Description
Hi everyone,
I just started using HtmlUnit so I hope I'm not doing anything wrong.
The problem I have is a com.gargoylesoftware.htmlunit.ScriptException when i click on a page button, i debugged the code to see where the exception is generated and i found out that in some cases it's possible that the getStyleAttribute method of the CSSStyleDeclaration class throw an ArrayIndexOutOfBoundsException.
The specific line are theese ones (from 203 to 207 in the CSSStyleDeclaration class):
if (values.length > 3) {
return values[3];
} else {
return values.length > 1 ? values[1] : values[0];
}In some case i get a zero length values array that in the last return line results in an java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0.
This are the variables i see while debugging (if you need other details please just ask 👍):
This is the complete exception as logged by HtmlUnit:
