http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17002 Problem with index property Summary: Problem with index property Product: Struts Version: Unknown Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Controller AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I have changed the PropertyUtils in the public static void setIndexedProperty (Object bean, String name, int index, Object value)method I have added the following code because I have a null pointer exception the array is null. if (array != null) // CODE ADDED if(!array.getClass().isArray()){ if(array instanceof List) ((List)array).set(index, value); else throw new IllegalArgumentException("Property '" + name + "' is not indexed"); } else {Array.set(array, index, value);} Now I try to explain because I have this exception, I have a Form Bean A with a property that is an array in this array are stored the index of selected row in the table so when the rows are selected if I go to another form bean B by using a forward to another action mapping. Also this new bean has the same property of A but the array is not initialized and of couse will have different size. So when Struts tries to populate the form bean B found the parm in the request and try to initialize the property of B (but in my case is wrong) so it has a null pointer exception. If I add the check if the array is null the problem is solved. Could you ask me if you want introduce my fix in your code. The version of Struts tah I use it is that shipped with WSAD v. 5. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
