Problem creating a new row when using tabbed regions

Question

I am new to JHeadstart and ADF and have been using the evaluation version of JHeadstart (in JDev 11.1.1.3) to judge its efficacy for a new significantly-sized application. As part of that evaluation I have created a small application (you can do this with HR schema using say the Departments table) with a single entity and VO. On JHeadstart I have then placed some of the fields into multiple Item regions within a Tabbed region on the same page and below the Group (layout style Table, Table Overflow Style below With Splitter). Existing rows display fine and I can view the data on the separate tabs.
However, if I try to create a row, I can fill in the data on the main region, but if I fill in data on the first tabbed region I cannot switch to the next tab without an error being generated.
e.g. using Departments - fill in DepartmentId and DepartmentName on main region, fill in ManagerId on first tabbed region and try to switch to second tabbed region to fill in LocationId:
Missing mandatory attributes for a row with key null of type HRModule.DepartmentsView1
Attribute DepartmentId in HRModule.DepartmentsView1 is required.
Attribute DepartmentName in HRModule.DepartmentsView1 is required.
If you save, then you can navigate.
You can also demonstrate something similar (different error message but probably the same root cause) on the myJHSTutorial demo. If you navigate to an employee off the regions page and try and create a new employee (using the '+' button below the 'Employees' label), then the tabs are not refreshed and any attempt to change the tabs results in an error
Failed to validate a row with key oracle.jbo.Key[999 ] in HRModule.EmployeesView3
Attribute Salary in HRModule.EmployeesView3 is required.
Salary must be between 6000 and 12000 for this job.
The JHS devguide does not help. Any thoughts? I can send the HR sample if you wish.

Answer 1

OK, I was able to reproduce this. The problem is that when you switch tabs, a partial page request is send to the server which does not include the items filled in the table row itself, hence these items are not updated in the underlying view object row.
Solution is to have a partial trigger at the table or group level listening to tab events. We will add that to the next release, but you can also apply the fix yourself by adding the following lines to the stackedRegionContainer.vm template:
#if (${JHS.current.pageComponent.tableLayout} && !(${JHS.current.pageComponent.hasOverflowInline}))
## when creating a new row in a table, and using overflow right/below, when switching overflow tabs
## the items filled in the table itself must also be processed as part of JSF model update phase, to
## prevent required item error when clicking another tab in overflow area
## we can enforce this by making the whole group listen to tab events
#ADD_CUR_GROUP_PARTIAL_TRIGGER("#REGION_ID()Tabs")
#end
Add these lines just before the line starting with
<af:${elemName}
