Making a field mandatory and not be able to exit page until it is filled up

Posted on by Community Member

So we developed a custom module when clicking an action button the status is set to returned. This makes the field Reason Code form control for the header and lines mandatory.

Problem is, you may still exit the form even if i set the form control mandatory after clicking the action button.

I tried overriding datasource methof ValidateWrite but it does not seem to do the job. Can anyone provide me a solution?

RE: Making a field mandatory and not be able to exit page until it is filled up

Hi reignheart05,

In AX it's a standard behavior, when you create or edit a record and then can close a form without saving your changes.

I suppose that on a button click you are updating a filed value and saving it, instead of this, you can try to modify value without saving the record. In this case when user will try to save it without populating mandatory fields he will get an error. If user will press "Esc" to close the form without saving he won't save change to a status field as well, so record will be rolled back to initial state.

It's impossible to prevent user to close the form because he always can terminate AX client using task manager or event turn off PC :) So you need to develop your functionality in a way when you data is consistent on each step.

Hi,

You can override canClose() method of the form. In this method you can do validation the value. If it's not set then you need return false. So the form will not able to be close even though by press ESC button.

How do you modify a value without saving a record?

My problem is that users may exit record even though the field reason code is mandatory and may still exit and the record gets saved eitherway.

What code do you have now ?

Yes, you can go with canClose() method, but as I mentioned before, user can close form in not "gentle" manner and in this case you will have "broken" data in your application, if you don't believe that it could be done intentional, just imagine that he lost a connection with AOS or client crashed.

Hi Ievgin,

Just got your point.. you can force close such as ending process.

Actually my action pane button. Just changes the status of the record and the line record.

Then makes the reason code form as mandatory.

I'm thinking of making another form that will get the lines and you may set the reason code in there. And if you don't "Ok" it should not save.

It took me a while to figure out but this should really be similar to posting process for inventory(InventTransferParmShip). Except that it only updates status.

That's a good idea. If user will provide a reason code you will change a status, otherwise you will do nothing.
