Hi,

I want to pass multiple records in arguement, therefore i have added them into container but I am getting the following error. Could not understand what's wrong. Please help.

The code-

str             userNameCon,UserLicenseCon,results;container       conUser,conLicense,record;Args        args = new Args();record = conIns(record,1,conUser);record = conIns(record,2,role);record = conIns(record,3,field.valueStr());results = con2Str(record,',');args.parm(results);

I am getting the error in args.parm();

I have the same question (0)

This seems to be your code when I throw away unused variables.
container record; record = conIns(record, 1, conNull()); record = conIns(record, 2, role); record = conIns(record, 3, field.valueStr()); str results = con2Str(record, ','); Args args = new Args(); args.parm(results);

It's not runnable, because it depends on an undefined variables called role and field.

Which of the statements is throwing the exception? If it's about role, what is the data type of the variable?

The screenshot is from F&O, therefore I'm going to move this thread from the AX forum to an F&O forum.

Hi Martin,

I had edited the code so missed to declare the Role.

It is the buffer of

SecurityLicenseRole role;

Also the the conUser contains the following code -

conUser = conIns(conUser,1,Table.Id );

And the field.valueStr () is the form field value which I am using

That's hard to believe, because there is no conversion involved.

Can you give us code that we can run and see the problem for ourselves? Without unknown variables like field.

Hi Martin,

Please find the whole code

SecurityLicenseRole role; public void clicked() { super(); int recordsCount,i; str userNameCon,UserLicenseCon,results; container conUser,conLicense,record; UserLicenseView userLicenseView; Args args = new Args(); recordsCount = LicenseTmp_DS.recordsMarked().lastIndex(); LicenseTmp = LicenseTmp_DS.getFirst(1); while(LicenseTmp) { conUser = conIns(conUser,1,LicenseTmp.Id ); conLicense = conIns(conLicense,1,LicenseTmp.License); LicenseTmp = LicenseTmp.getNext(); } record = conIns(record,1,conUser); record = conIns(record,2,role); record = conIns(record,3,LicenseField.valueStr()); results = con2Str(record,','); args.parm(results); MenuFunction menuFunction; menuFunction = new MenuFunction(menuitemActionStr(LicenseBasis), MenuItemType::Action); menuFunction.run(args); }

I'm sorry, but I can't execute your code, because depends on some form context, such as a form data source.

But I think I see the source of your bug. Unlike your code, the following snippet can be pasted to runnable class and executed, so you can see the result for yourself.

SecurityLicenseRole role; con2Str([role], ',');

You can see that most of code you gave us is irrelevant to the problem - you didn't do enough work on bug isolation. You didn't even correctly identify the place where the error is thrown, which is necessary to understand and resolve the issue.

The problem is that some values you're trying to convert to a string with comma-separated values aren't primitive. You should convert them to a string before passing the container to con2str() - or maybe the whole idea of converting this data to a string is wrong.

Hi ,

So passing the role to container was error. Instead i used this and it worked-

args.record(role);
