Hello pvi,

Thank you for contacting National Instruments.

If you remove the Invoke Node from your Open Tree Control VI the problem disappears. Why were you using a "Clear" invoke node? This is what makes your tree collapse upon execution. It seems to work without the invoke node.

I have attached the altered Open Tree Control VI.

I hope this helps,
