Hello,
Should I send you a project that shows errors? If so, how exactly do I do?

> Hello,
> When I start writing a code (such as a class name), it says "please wait" and
> then a list of possible classes is displayed.
> Or, if I write a dot after the object name, the same is done, and then a list
> of related methods and fields is displayed.
> Sometimes it happens that "please wait" is displayed for a few seconds and
> then it will throw an error.
> *A java.lang.RuntimeException exception has occurred.*
> *However, the system should continue working without further problems.*
> Clicking Show Details will appear.
> {code:java}
> java.lang.IllegalArgumentException: Argument compositeType cannot be null.
