Thread: LUNA: A new step into the unknown of scripts

returns a boolean type as expected, so no modification needs to be made at this level

You are (again) 100% right. There is some corruption in the LUA code that changes the country string (pointer) by one byte.

Code:

works.

crashes (real crash).

Now I need to find why the address that is correct right before the function containing the code gets increased by one byte. I already solved a similar issue whether a function was missing a "self" argument.
These are probably delicate locations where LUA code calls C-code.
Will get there ... eventually. Thanks for all the help and the tip on sc_InfoMessageBox (very useful).

this seems to be what the old scripts did

local selCountry = MODEL.map.cursor.address.country() --> "_BEL"
if selCountry ~= "" then
AddressSearchResult.selectedCountry = selCountry:sub(2, 4) --> "BEL"
if AddressSearchResult.selectedCountry:sub(2, 2) == "*" then
selState = MODEL.map.cursor.address.state()
if selState ~= "" then
AddressSearchResult.selectedCountry = selState:sub(2, 4)
gSavedSelectedState = AddressSearchResult.selectedCountry
else
gSavedSelectedState = nil
end
end
.....
AddressSearchResult.streetsInState = MODEL.address.search.support_streetsearch_in_state(AddressSearchResult.selectedCountry) --> "BEL"

About sc_InfoMessageBox (very useful).

need to be used as it to obtain a visible result
sc_InfoMessageBox("Result: /"..tostring(type("very useful").."/") --> /USERDATA/ , /STRING/ , /NIL/ ,......

That is also what I have. But even when I put the constant string "BEL", it crashes. Same with "FRA" etc. It does not crash with "USA" but also returns false, but than again I don't have USA maps loaded.
Anything with an underscore goes, but always returns false. I also tried with a local variable (also with wide string): always crash.
Interestingly, when I put the country in lower case, it does not crash and again returns false. Function "sc_HasCountryStates" seems to imply that countries with states start with a lower case.

Look like it requires some additional code like

or classic search backend code is broken for LUNA since I have other unexplained crashes...
