Error on EditBox SetFocus

[Former user]

I catch error when i set editbox to SetFocus at Centos 7 64bit. No error when i click on TDropdownEditButton Login (btnDatabase) at first time, then i close login and click login again, it raise error when i click again on TDropdownEditButton Login. It's normal when i delete editbox SetFocus (edtDatabase.SetFocus) at LoadcmbDatabase. But in Windows 10 LTSB 64 bit it's normal, no raise error. Can you explain to me what wrong with SetFocus. I use RadStudio Tokyo 10.2.2 (Build 2004) ,TMS FMX UI Pack 3.6.6.0, and UniDAC 7.1.4. My Linux is Centos 7.4 64bit. To run this Project, please put file myintransit in Documents Folder.

It may related to memory management, i didn't noticed code where you free fLogin. Try to call - fLogin.DisposeOf after fLogin.ShowModal. Calling DisposeOf for form is required because there lot's of internal link to form and ARC doesn't work.

You're right. It work. I must use DisposeOf for all form to free memory. Before firemonkey flag deprecated at Release, I always use Release to free all delayed component at memory. Then i change to caFree at Close Form. Thank you very much sir. You can change this Issue status to Resolved.
