Here the important parts:

I think it was mentioned before, but the app folder mapped to "resources" is not writeable.

So your script cannot work.

On first run, you need to check whether the stack that needs to be saved exists already in the app "documents" folder and if not, copy it there from "resources".

What does this tell you?

on mouseDown
   put the text of widget "fi" into _gUserName
   put _gUserName into field "la"
   if the environment is "mobile" then
      mobileVibrate 1
      --save this stack
      put specialfolderpath("documents") & "/Working.livecode" into tStackToSave
      if there is a file tStackToSave then
         save stack tStackToSave
      else
         put specialfolderpath("resources") & "/Working.livecode" into tStackFromResources
         put url("file:" & tStackFromResources) into url url("file:" & tStackToSave)
         save stack tStackFromResources
      end if
   end if
end mouseDown

I was thinking the same thing. It would be much easier to just write a text file to the documents folder. If the app is only for mobile it doesn't even need to be encrypted since users can't directly access it, though I probably would use encryption if the info is very sensitive.

no, no, no!

At that point (on mousedown) it is already much too late, everything has to happen
before you open stack "WORKING".

The logical workflow is like this:
1. You create a standalone from the "SPLASH" stack.
All of your inclusions like the ASK and ANSWER dialogs and all externals you are using need to go into stack SPLASH!

2. On the cellphone you start the app (= stack "SPLASH").

3. The app (= stack "SPLASH") checks if there is already a stack named "WORKING" in the users DOCS folder.

4. If there isn't the app (= stack "SPLASH") copies that stack from RESOURCES to DOCS.

5. THEN the app (= stack "SPLASH") opens that stack from the DOCS folder.

6. NOW stack WORKING can be saved.

Capisce?

You need to create a little script in the SPLASH stack:
This goes into the stackscript of SPLASH!

Code: Select all

on openstack
   
   ## Neccessary so all opened stacks can access the inclusions of stack "SPLASH"!
   start using this stack
   
   ## Prepare filenames:
   ## Stack in RESOURCES
   put specialfolderpath("resources") & "/working.livecode" into tSourceStack
   
   ## Stack in DOCUMENTS folder
   put specialfolderpath("documents") & "/working.livecode" into tTargetStack
   
   ## check if we already opened the app = the WORKING stack is already in DOCS folder
   if NOT (there is a stack tTargetStack) then
      
      ## Now copy the stack to the DOCS folder
      put url("binfile:" & ttSourceStack) into url("binfile:" & tTargetStack)
   end if
   
   ## NOW we can open that "new" stack that NOW can be saved
   go stack tTargetStack
   hide stack "splash"
end openstack

Now you can do this in the WORKING stack:

Code: Select all

on mouseDown
   put the text of widget "fi" into _gUserName
   put _gUserName into field "la"
   if the environment is "mobile" then
      mobileVibrate 1
      ## This will work now:
      save this stack
...

Best
