Type Incompatibility Error with Checkbox

jgriffin asked 8 years ago
I'm in the process of converting a very large eXtender app that was originally written in GP v10 up to GP 2013 R2. The app is heavily customized with GP scripts all throughout eXtender. I have found solutions or workarounds for just about everything with the exception of checkbox fields. I'm finding that if you attempt to use a checkbox field as a parameter anywhere in a GP script a 'Type Incompatibility' error is throw at runtime compile. 

GP Script – 
warning str(<Printed>);
At runtime this throws the following error:

Type incompatibility 'New Total'.
inout anonymous table EXT_Data_TEMP; 
local boolean i272=false;
local boolean o272=false;
warning str(o272);
if i272 <> o272 then 
  'Field ID' of table EXT_Data_TEMP = 272;
  'Line Item Sequence' of table EXT_Data_TEMP = 0;
  change table EXT_Data_TEMP; 
  if err(table EXT_Data_TEMP) = OKAY then 
    'New Total' of table EXT_Data_TEMP=o272;
    save table EXT_Data_TEMP; 
  end if; 
end if; 

It looks like the local variable is correct as a boolean, but there is no conversion being done at the table level for the temp table holding the current form data.

Anyone have any ideas or workarounds? Thanks!

I tested this on extender 12.0.0102 on GP 2013 SP2 (not R2).

in my extender window, I added a checkbox.

then I put an action on the checkbox itself to run a GP Script.

in the script, I did what you did

warning str();

t properly displays 1 and 0 depending.

So looks like i’m not having a problem on this issue.

I’d have to find a 103 build to test on R2 but I don’t believe there is a meaningful difference between the versions except for the security error that 103 fixes.
