insertString crashes in Groovy
Posted: 10 Nov 22, 17:43

For making a menu I use in BeanShell this code:

	linkIndexPage= "<li><a class=\"nav-link\" " + preString.substring(indexHREF) + "</li>";			
topNavigation= insertString(topNavigation, linkIndexPage, indexUL+4);

If I convert this to Groovy I get this error message:

groovy.lang.MissingMethodException: No signature of method: java.lang.String.positive() is applicable for argument types: () values: []
Possible solutions: notify(), size(), tokenize() in navigation-bar.inc at line number 3

What should I change here?

Edit

insertString is coded as:

public static String insertString( String originalString, String stringToBeInserted, int index)  { 
        String newString = originalString.substring(0, index + 1) 
                           + stringToBeInserted 
                           + originalString.substring(index + 1); 
        return newString; 
}

This is the solution:

public static String insertString( String originalString, String stringToBeInserted, int index)  { 
        String newString = originalString.substring(0, index + 1)  + stringToBeInserted   + originalString.substring(index + 1); 
        return newString; 
}

Ah, it turns out that the + operator needs the first argument on the same line. Interesting.
