CoC on Modifiedfields not working

(0) ShareShare
ReportReport
Posted on by Tony zhong 903

Hi guys,

I created an CoC on ModifiedFields for table ProjCostTransSale in hope that I can insert some procedure when the TransStatus is changed. However it didn't work and while debugging, I found out my break point not even hit my CoC

I even tried to put break point in ProjCostTransSale table, Update method it self, but the breakpoint "ignored".

Anyone can suggest what happened and what should I do to intercept when some field in this table is modified ?

Thanks,

I have the same question (0)

    What do you do when you expect modifiedField() to be called?

    Note that modifiedField() and update() are called at completely different times. modifiedField() gets called immediately after changing a field value in a form, while update() is called later, when a record is being saved to database.

    Hi Martin,

    In modifiedField() I would like to run some update_recordset to another table if the the field modified to certain condition. When you said chaging a field value in a form, does it meant it will be called "only" when it is change from a form ? if it was changed by backend process, it will not hit this ?

    Thanks,

    Updating other tables from modifiedField() is usually a bug. Think it through again, please. The problem is that the record with the modified field doesn't have to be actually saved to database (because the user closes the form without saving, a validation fails, a connection gets interrupted and so on). But you already changed another table based on this change that never happened. The correct approach is updating other tables when this table is being saved to database (in the same database transaction, therefore both changes either happen together or don't happen at all).

    modifiedField() is indeed called automatically only from forms. It can be explictly called from X++, but it's not called automatically when you update a table from code. That's another reason why your design is wrong and you should run the logic in update() (and possibly insert() and delete()).

    Correct, the modifiedField method is not called in code. So that's why your extension was not called. The update method of the table is also not guaranteed to be called by the system. Check the code with the debugger.

    Hi Martin,

    Understood and noted. I moved the update_recorset() in Updates() method. It works fine now.

    Thanks for your guidance.

    Thanks,

    But just one more thing,

    As mentioned before, I actually put the breakpoint in the original table "ProjCostTransSale" Update method as well, while the CoC's breakpoint on the same Update method hits (and stop), I wonder why the breakpoint in Update method of original table it self not working ?

    Thanks in advance,

    For example, you may have Visual Studio configured to load debugging symbols only for objects in your solution.
