Hi all.
While using frames and Docked Designer, I noticed that :
1) create a new frame with controls.
2) embed the frame on a form
(the above stage works fine)
3) add an other control in your frame
4) go back to the form
this does not shows any change so the new control does not apear. However if you compile and run then it works fine the control is there
afterwhat you close and restart Lazarus IDE, then the control is also there.
So, I guess DockedForm Editor miss an update stage when working with frames.
Give iit a try, Thank you
