Global variable loosing value?

wilk_u

Hey, I'm still learning this..
I defined a global variable in codeunit, assigned it a value in one function of that codeunit when launching a form, and in after validate trigger on that form i want to launch another function form that codeunit where i want to use value of my global variable, but its empty.
What's going on exactly? Only direct assignment operation on that variable is when I assign it a value in first function.
Regards.

I have created new codeunit with 2 functions
set and get

Set()
Num := 1000;

Get()
MESSAGE('%1',Num);

Num is a global variable of type integer..

Created new form and called Set function onOpen form.

Added a text field and called Get function OnAftervalidate of that field
message showed 1000

I didnt have any problem..

Your Codeunit variable needs to be global as well.

Maybe I'll be more specific
Function executes after pressing button.
Codeunit.Function(GivenRec);
user selects record and then presses button.
It operates on gl entries.
Function goes like this:
table gl entry has additional field lests say AppID
if givenRec.Apply ID = ''
then CurrGLEntry SETRANGE(givenRec.EntryNo)
ELSE
currGLEntry.SETRANGE(givenRec.Apply ID)
//my global variable is AppID Code
AppID := givenRec.Apply ID;

I also tried to create another global variable TempEntry And Tempentry.TRANSFERFIELDS(CurrGLEntry);
to get Apply ID form it.

Then
FORM.RUNMODAL(Form,CurrGlEntry);
//

I checked in debugger, it sets correctly a value to AppID or TempEntry. But when i try to use these values they are empty.

Please help..

...aaaand, where you try to get this value?

In another function in that codeunit

Function2()

IF AppID <> comparedWithSth THEN...
and here that value appears as empty

i am guessing you have declared your codeunit in the form too, and are trying to read the variable from there. You have to realise that by default, every time you declare a variable of your codeunit, it will be a seperate instance ! Either set the "single instance" property of the codeunit to "yes", or make function in the form you want to run to pass the values.

You may be right if i understand You correctly.
I declared codeunit in form as global variable, and trying to execute functions from codeunit. Then i have empty values. So You say to declare single instance codeunit? I heard its not safe.. Is that right?
