RelationTree doesn't show child (secondary)

Strange things: added RelationTree control template, defined Primary and related Secondary tables:

but Secondary file doesn’t appear in the properties.

What I am doing wrong???

ABC, Clarion10

I haven’t looked at the RelationTree in over 20 years, but have you tried adding the table to “Other Files”?
You might need to save/reopen the procedure, as well.

Is the seconary a 1:Many ? RelationTree is a bit funny depending on relationship

yes sure it is 1:many

I did exactly as in SV example app - it should work like this but it doesn’t…

Have tried also SVMultiChildRelationTree - Multi Child Relation Tree Control and it works for the same tables but really do not need many settings as it has…
