Hi Aarthi,
I'm using 10.1.3.1.0 and its navigation seems to be different from that shown in the screenshot.
When i right click on .jpr, i cant view the "New Business Components package" option.
Thanks,
Vivek

Vivek,
It is done in 11i jdev.you can right click on your project and then goto business tier-ADF business components and then select VO or EO.you can straight away specify the package name there.In r12 jdev it is not needed to create bc4j package explicitly.

Hi Aarathi,
My requirement is to develop a Oracle Form style Master-Detail data entry Form, is it possible in OAF or Not?
I developed a sample form and created all required BC4J components like EO, VO, viewlink and entity association but it is not picking up the foreign key value. What may be the reason? I have set the newly created row as current row for Master VO.
Thanks in advance
Regards,
Reetesh Sharma

Reetesh,
No it is not straight forward in OAF. However you can achieve this by tweaking a little.Can you attach your project zip file in the forums so that I can have a look at it.

Aarthi

Hi Arathi,
Thanks for your propmt response.
I've already compeleted that project and handelled Master-Detail Relationship manually means I created two regions while querying I was firing query on both the regions simultaneously and while saving the data I will pass foreign key value manually to child block.
I just want to know if any better approach is there.
Best Regards

Hi Aarthi,
I created a Master-Detail OAF page following the steps you listed in the document. But I am not getting any data when I attach the detail region. If I just run the the page with the Master Region alone, I could see the data.
I am fairly new to OAF and I am having hard time to figure out what I missed.
Could you please help me out on this.
Thanks,
Akila.

Hi Akila,
Please post your query in the forum to get a prompt response as well as it is easy to troubleshoot from there.Do attach your myprojects as a zipped file.
