I couldn't reproduce this issue. Could you give me more information?

What did you do to generate it？Maybe i don't know how to use it.

Just drag-and-drop a java file from Package Explorer to the diagram.

What did you mean in your previous comment?

Hello, I am new to using eclipse and java, but I report the same problem, I am using Eclipse IDE Version 2023-09(4.29.0) and when I drag a class to the cld file, instead of inserting the class in it, it opens the file to edit it.
Use this path to install the plugin: https://takezoe.github.io/amateras-update-site/
and add this line to the end of my eclipse.ini file:
--add-opens=java.desktop/java.beans=ALL-UNNAMED

could you help me? I'm missing something?

After taking the steps to correctly install and use Amateras on Eclipse 2024 (Adding that one line at the end of the ini file), when i open a new cld file and drag the class onto the diagram, Eclipse interprets it as if i want to open the class to edit the code. The diagram editor is unresponsive when I detach the window and try to drag the class onto it. Furthermore I cant even edit the methods nor variables of a class created within the Diagram (only able to change the title). Hope this issue gets looked into, thanks in advance.
