Problem with variables declared in ClassDeclaration

(0) ShareShare
ReportReport
Posted on by Ghetz 2,987
This must be an easy one, but I'm quite new at programming in AX. The thing is I've created a class, and delcared the main function as static, so I can directly run it from the AOT. Inside the main method, I call another method1, and from this I call Method2, both void methods.. Now I have created a NoYes Variable in the ClassDeclaration. So when I call Method2 from Method1, I change the value of the NoYes variable to 'Yes', but when I return tu the Method1, the value of the variable returns to value 'No' Why is the variable declared in ClassDeclaration changing?? How Can I prevent this behaviour?? Thanks.. Regards.. Jack

    Use this as an example:

    class test
    {
        NoYes var;
    }

    static void main(Args args)
    {
       test t;
       ;
       t = new test();
       t.method1();

    }

    void method1()
    {
        ;
        this.method2();
       
        info(strfmt("%1", var));

    }

    void method2()
    {
        ;
        var = NoYes::Yes;

    }

    Thanks for your answer.. Certainly I'm using the debugger to see the value of the variable in each method.. In method1 the value is 'No'... Then from Method1 I call method2, and inside method2 I change the value to 'yes'.. However, when method2 finishes and returns to method1, the value of the variable is going back to 'Yes' My code is quite simple.. something like void method1() { method2(); if (!var) print 'OK'; } void method2() { var = YesNo::Yes; } During method2, i see in debugger that value of var changes from No to Yes, but when returning to method1, the value is No, even though var is declared in the ClassDeclaration()

    Hi,

    Can you paste your code?  It is most likely due to where you are setting the variable in Method1.  It would be really easy to tell if you showed the code.  One thing you can do is output your variable in every single method so you can see the value in each method call.  i.e.:  

    static void NoYesExp(Args _args)
    {
        NoYes var;
        ;
       
        var = NoYes::No;
       
        info(strfmt("%1",var));
    }

    Or you can use the debugger to see the variable values as you step through the code.
