APEX 10g edition bug??

Question

Hello
I have come across an issue when building the application. There is no way around it so far, and I can't think of anything despite many hours.
After having created the tables, I go to the next step of creating the application.
Once all the pages are organized within tabsets and tabs I notice that the field that corresponds to the Primary Key is not editable, that is, it does not have a text field where you can manually introduce the data. If it were sequenced by trigger I could understand that, but, I need to enter them manually. So, then I click on Edit Page, I locate the region, I click on Edit Report Attributes, I notice that it is by default put under Hidden (why??), so I change it to Text Field and applied and yes, the page looks cool now, just as I wanted. In any case I was not very happy why I had to do that for all of the pages, but I went on.
So now, that (it would seem thta) I can enter the data, when I click on Add Row to insert it, it brings an error saying that the data version of the database has changed since I started the update process, everything is messed up and you cannot add any row.
So, what is happening is that when the Application is created, the pages that were alright, are not anymore. That is, the column corresponding to the PK says only: PostCode_Display, (for one page), DoctorNumber_Display (for other page, etc) but you cannot introduce data because, as I said, there is no textfield. 1)
Does anybody have an idea why:
1) The columns of the PK for each page will present themselves un-editable when launching the tabsets and pages with their tabs.
2) Why if you edit the page from there, even if you manage to create the textfield to add the data it comes up with this:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "A884FA378C851786DDFE3A33709CB23C", item checksum = "EA5F789178309D21B6818803A970BB4F"., update "HR"."ADDRESSES" set "POSTCODE" = :b1, "TOWN" = :b2, "STREET" = :b3
Error Unable to process update.

Hello,
It depends how you want your PK populated.
What selection did you use in the wizards for the Primary key?
