Summary: IllegalArgumentException when using code completion on
Java class member
Key: NETBEANS-1495
URL: https://issues.apache.org/jira/browse/NETBEANS-1495
Project: NetBeans
Issue Type: Bug
Components: editor - Completion & Templates
Affects Versions: 10.0
Environment: Product Version: Apache NetBeans IDE Dev (Build
incubator-netbeans-release-345-on-20181002)
Java: 11; Java HotSpot(TM) 64-Bit Server VM 11+28
Runtime: Java(TM) SE Runtime Environment 11+28
System: Windows 7 version 6.1 running on amd64; Cp1250; cs_CZ (nb)
Reporter: Vít Suchánek
Attachments: ide.log
I'm adding new member variable in Java class. I use code-completion after "="
to add ClassName.getInstance():
"ClassName memberName = "
I suppose the problem occurs when code-completion should also add new import
for the ClassName. Nevertheless repeated usage of code-completion works OK most
offen.
Stacktrace:
java.lang.IllegalArgumentException: Argument compositeType cannot be null.
