Set paths using Paths/Settings dialog box not working

[WayneSherman]

Tested Lazarus / LAMW with:

Xubuntu 20.04 64-bit
installed using FPCUPdeluxe ver 1.8.2u
FPC/Lazarus Stable/Stable
also tested with FPC/Lazarus Trunk/Trunk
LAMW git (2021-Jun-05)

After a fresh install, the following LAMW.ini settings have not yet been set:
PathToAndroidNDK, PathToAndroidSDK, NDK, PrebuildOSYS

I run Lazarus and open the LAMW Paths/Settings window, and I have these problems:

1. If I set the "Path to Android NDK", the edit box gets cleared when I select an NDK version, or NDK Prebuild, or set the Android SDK path.

2. If I set the "Path to Android SDK", it also gets cleared when I change another setting (like NDK Version, Path, or Prebuild)

3. The NDK Prebuild combo box is populating with a long list of repeated entries for "linux-x86-32" and "linux-x86-64".

Work-Around: If I set these settings by editing the LAMW.ini file directly, then I can successfully create and build new projects.

Please provide installed NDK version.

Android NDK revision 22

Also tested with NDK rev 21.4.7075529 with similar problems settings the paths.

This has been fixed. The problem was caused by using OnActivate instead of OnShow to initialize the form controls. On Linux, the OnActivate event of the active form is apparently triggered when another dialog box is displayed (browse folder dialog) which was causing parts of the form to reset.

Fixed in commit: #a64eff3
