1. go to class declaration and make the following "FormBulidStringControl"
FormBuildStringControl controlFromDataAreaId,controlToDataAreaId,controlGeneralType,controlMainAccounts,controlDivision;
2. now in the "dialog" method write the following method,below the field where we enter value
controlFromDataAreaId = dlgFromDataAreaId.control();
FormBuildStringControl controlFromDataAreaId,controlToDataAreaId,controlGeneralType,controlMainAccounts,controlDivision;
2. now in the "dialog" method write the following method,below the field where we enter value
controlFromDataAreaId = dlgFromDataAreaId.control();
3. now in the ""dialogPostRun" method write the following code
controlFromDataAreaId.registerOverrideMethod(methodStr(FormStringControl,Validate),
methodStr(TTC_EOM,fromtoEntity_Validate),
this);
4. now make a new method, in this case ""fromtoEntity_Validate
public boolean fromtoEntity_Validate(FormStringControl _control)
{
boolean ret = _control.validate();
select DataArea from companyInfo
where companyInfo.DataArea == _control.valueStr();
if(companyInfo)
{
ret = true;
}
else
{
ret = ret && checkFailed("Entity does not exist");
}
return ret;
}
