Q1) This should be working. When do you set Tree1.NoOwnerShapes to false? in the OnCreate event of the form? or just when saving the tree?

Q2) Sorry, I don't understand your question. Do you want to know how to use the LoadTreeFromStream and SaveTreeToStream functions? Or weren't you aware of these functions?

I still problème , if i execute this code>> no execption but infinite blocking !!

Can you send me your source code in which you receive this problem?

I am experiencing the same problem. Application freezes because of looping in procedure TeeTreeFindGlobalComponent.

Any help would be appreciated.

Thanks
T.S.

First, please note that circular references are not possible in teeTree.

If you do not have circular references, please provide me a souce-code example which can mimic this wrong behavior

The issue arose from the fact that there was a form with name = '' currently created in the app. I removed the form, and the problem went away.
