NetBeans: Auto-generated classes failing to compile

1050453

Below is the code in question.Normally this code would work, because it used to work as it is until suddenly i got errors on all java.awt.event.ActionEvent variables. Basically the problem i have is not a bug or code error, because that code used to work as it is.i even tried uninstalling Netbeans and reinstalling, even installing later versions of the jdk but still seems like that ActionEvent class is missing somehow and thats the sole cause of the bugs because all of them point to an ActionEvent instance, for example mouseClicked.So i am now under the impression that maybe my jdk lost that class, or its disabled in Netbeans.Below is a copy of the full program and a screenshot of the error messages as they appear in Netbeans attached:

below is a screenshot of the code as it appears in my Netbeans:

1050453

so in my Netbeans all my java.awt.event.ActionEvent instances generate an error:

cannot find symbol

symbol:class ActionEvent
location: class event

for example:

private void jButton2ActionPerfomed(java.awt.event.ActionEvent evt) {

.......

.......

....}
