Data entity method mapDataSourceToEntity() is not executed

Posted on by Rati Sharabidze 612
Hello,
 
I have extended the entity PdsItemBatchAttributeValueV2Entity. I added mapDataSourceToEntity() to it using COC.
I have virtual fields to treat. postLoad() works fine but I want some logic only in case if I want to export, not import.
 
The debugger is not popped when I had a break point in this method or even the event handler onMapingDatasourceToEntity.
 
Does anyone have an idea of why this is happening?
 
Thank you in advance!
Kind regards

    Maybe a post from somewhere mislead me. postload() works fine.
    Thank you Martin.

    postLoad() is executed when an entity record is read from database. There you can populate virtual fields before exporting data from F&O. It can't be used for data import, because that would require setting values of underlying table fields, not values of virtual fields.
     
    Can you please explain your exact problem with postLoad()?
     
    As far as I know, mapDataSourceToEntity() indeed isn't called in this scenario and the documentation is right when saying that you should use postLoad().

    Thank you for responding Martin.
    As I know, postLoad() is executed in while exporting and while importing as well.
    I want to give value to virtual fields through x++ only while exporting.
    Therefore, I decided to use mapDataSourceToEntity(). I added it in my extension class.
    The code which was in postLoad() and which was working, did not work there.
    Therefore, I set a break point exactly on the line of "COC's next" and started debugging.
    The debugger was not even popped.
     
    Then I tried the equivalent event handler, copied directly from the entity event list and I had same scenario.
    I think I am missing something but I could not figure out what exactly.
     
    Kind regards

    Can you elaborate your question, please? I don't understand the sentence "I want some logic only in case if I want to export, not import".
     
    If you mean that you want to handle export only, postLoad() is a solution, because it indeed executes only when exporting data from F&O.
     
    If you're actually interested in import to F&O, then you need mapEntityToDataSource() instead of mapDataSourceToEntity().
