No matches found while there is an expected result [message #1836618]

I am trying to write some queries for my models. However, in all of my queries, there are no matches while there are expected results.

The attached screenshot shows an example of my query. Could you please help me check it?

Thank you so much,
Thuy

Dear Thuy,

thank you for you interest in Viatra Query.

It is clear from your screenshot that your instance model is a dynamic EMF instance, rather than a regular instance model that is to be expected in most use cases.

In case you have to work with dynamic EMF models, you must enable dynamic EMF support in Viatra. When using the Viatra GUI ( "Query Results" view), please turn on the dynamic EMF support in your Eclipse Preferences (it is not turned on right now, hence the line "Dynamic EMF mode: false"). If you have to interact with dynamic EMF programmatically (this is less likely), enable the same thing via your EMFScope.

Dear Gabor,

Thank you so much for your reply. After enabling Dynamic EMF mode, I got the expected result.
