JDev/ADF sample - Create Operation for Master-Detail Relationship

  • Create Operation for Master-Detail Relationship. Its very frequent requirement in Oracle ADF applications, when developer needs to implement Master-Detail relationship with Create functionality. Actually, its very easy to implement Master-Detail in ADF, the same is for Create operation. However, there is one thing you should know, especially if you are new to ADF. Let's say you are implementing functionality to allow users to insert data into Master and into Detail, its fine - you can just drag and drop Create or CreateInsert action from Data Control. But you will face a problem, when user will try to insert Master and Detail record during the same transaction. I'm describing in this post how to avoid such problem.

Para evitar la salida de un error indecifrable, Andrejus nos muestra un tip muy útil en este post.

Hello Andrejus ,
We have a requirement to show Master-Detail data in hierarchical format for which I have used RichTree. In the Tree, currently I am able to save detail data only for the current node. That is, if I edit multiple nodes and click on the Save button, only the last updated node is getting saved. Can you please tell me how do I save all the edited nodes at one click of the Save button?

Default behavior of Commit action is to save all rows at once.
