----------------------------------------
Summary: Regression from NB 8.2: Undoing Introduce Field causes
incorrect "Local variable hides a field" and "No valid expressions found" error
when attempting to introduce another field
Key: NETBEANS-196
URL: https://issues.apache.org/jira/browse/NETBEANS-196
Project: NetBeans
Issue Type: Bug
Reporter: Daniel Trebbien
Steps to reproduce:
# Start with the following file:
{code:java}
package hintstest;
public class UndoIntroduceTest {
public void test() {
String str = "test";
}
public void test2() {
String str2 = "test2";
}
}
{code}
# Place the editor caret within {{str}}. Right click, select *Refactor >
Introduce > Field…* Pick the {{String str = "test";}} expression. Select "Ok"
on the "Introduce Field" dialog, using the default settings.
# Undo. Notice that there is now an incorrect "Local variable hides a field"
warning on {{str}}.
# Place the editor caret within {{str2}}. Notice that "usages" highlighting
does not work; NB is still highlighting usages of {{str}}. Nevertheless, right
click, select *Refactor > Introduce > Field…* An "Error" dialog pops open with
the message "No valid expressions found".
I tested the above steps in NetBeans 8.2 Patch 2 (NetBeans IDE 8.2 (Build
201609300101)) and did not observe these issues, indicating a regression.
