jListView.GetCheckedItemPosition always returns -1

Today I updated lawn and when I compiled a project of mine I noticed that jListView.GetCheckedItemPosition is always returning -1, maybe I has something to do with a recent update?

Can you do some diff in "jListView.java" for "GetCheckedItemPosition"?
[LAMW folder "...\android_wizard\smartdesigner\java" ]

Like this?
Code: Pascal
[Select]

[-]

-
// Fix GetCheckedItemPosition [by TR3E]
+
public
int GetCheckedItemPosition
(
)
{
for( int i = 0; i < alist.size(); i++ )
- if( alist.get(i).checked )
- return i;
-
+ if( alist.get(i).checked )
+ return i;
+
return -1;
}
It doesnt seems to have changed...
But whenever I use GetCheckedItemPosition it returns -1 wherever there is a item selected or not.

Maybe @TR3E can help here....
[Please, if possible] Can you do a simple project/example and put it in some open drive?
Thanks!

if I compile this with an older version of LAWN, GetCheckedItemPosition returns the checked item position ok.

I changed GetCheckedItemPosition for GetItemIndex, I was misusing GetCheckedItemPosition to get the Index of the selected item and Adiv fixed it, sorry.
