Double update ？

[Liam-choung]

Description with steps to reproduce

Add a qDebug() inside the setInData implementation of a NodeDelegateModel.

Trigger a data update from an upstream node.

Observe the console outputting the log twice with a small time gap (~40ms).

Hi author,
I noticed an interesting behavior where every node's setInData function is being called twice during execution. This leads to redundant computations for each update cycle. Is this a deliberate design choice for UI/Data synchronization, or should I be handling idempotency manually within the nodes?

Qt Version

QT 5

Operating system

Do you connect manually nodes (in code) before data update ?
