[Lazarus] Still some problems with PackageEditingInterface.DoOpenPackageFile

[Ludo Brands]

Hi,

In case I recreate a package that is already installed in lazarus,
PackageEditingInterface.DoOpenPackageFile will bring up the package but as
soon as I hit compile, it shows a message that the disk file has changes in
between. 
Ignoring or reloading, crashes lazarus with (ignoring in this case):

TPkgManager.DoCompilePackage A AXVLC_1_0_TLBP 0.1 Flags=[]
[TMainIDE.Destroy] A
TApplication.HandleException Access violation

It seems installed packages are already pre-loaded and the window that is
brought up with PackageEditingInterface.DoOpenPackageFile is actually a
cached version before the overwrite. This is somewhat confirmed when I
delete the .lpk file of an installed package as it will bring up the package
editor for that package with the warning that the diskfile has changed. 

I'm doing now
if PackageEditingInterface.FindPackageWithName(PkgName)<>nil then
 
PackageEditingInterface.DoOpenPackageFile(sDir+PkgName+'.lpk',[pofRevert],fa
lse)
else
 
PackageEditingInterface.DoOpenPackageFile(sDir+PkgName+'.lpk',[pofAddToRecen
t],false);

but FindPackageWithName returns nil. What can I do?


Thanks, Ludo
