Hi Folks,

I want to declare a customized Global variable in form extension class and want to use in Other datasource field extension class of that form.

I declare Variable as per below code in Form extension class

[ExtensionOf(formstr(XXX))]
final class XXXFrm_Extension
{
    
    public       NumberSeq              numberSeq;

    void init()
    {
        if (! numberSeq)
        {
            XXX
        }
       
        next init();
    }

And want to use NumberSeq variable in other extension class like Data field. But I'm getting error as "NumberSeq is not declared"

[ExtensionOf(formDataFieldStr(XXX,ProjTable,ProjId))]
final class XXXFrm_ProjIdFieldCtrl_Extension
{
    public void modified()
    {
        next modified(); 

       

        if(projTable.projid)
        {
            projTable.XXX = rProjIdnew;
         }
         
    }
}

Please help me out this.

Hi D365FO Avatar,

Try to use element keyword to get the global variables in the form like below.

element.numberSeq;

If it doesn't work create one parm method in the form extension and simply return the buffer.

[ExtensionOf(formstr(XXX))] final class XXXFrm_Extension { public NumberSeq numberSeq; void init() { if (! numberSeq) { XXX } next init(); } public NumberSeq getNumSeq() { //return the buffer return numberSeq; } }

Now you can call the above method in any of your extension class using element keyword or form run object.

[ExtensionOf(formDataFieldStr(XXX,ProjTable,ProjId))] final class XXXFrm_ProjIdFieldCtrl_Extension { public void modified() { next modified(); NumbeSeq numSeq = element.getNumSeq(); if(projTable.projid) { projTable.XXX = rProjIdnew; } } }

Thanks,

Girish S.
