Querying a View Object after a Row has been inserted

Question

Hi All,
I have a query as to whether something can be done or if I should be approaching my problem in a slightly different way.
First an explanation of what I am trying to achieve:
I have a header record that deals with a new user request. From one of the pages within the train one or more of several different ‘applications’ can be selected. When an ‘application’ is selected I am navigating to a new page, it queries the linesVO to see if any lines exist for that ‘application’, where they don’t it adds lines to the VO each representing ‘questions’ specific to that ‘application’. This works fine, however if I then come out of that page back into the train and then back into the same page specific for the same ‘application’ the initQuery is run and the lines I have just created are not found, it then tries to reinsert the question lines but will error as primary key validation fails. I do not want to commit after coming back from the lines page as the user has not specified a save, adding a save to the lines page would also cause the header to commit.
Now the Question:
Is there a way of ensuring that I can run my created method ‘initQuery’ which sets a where clause and calls ‘executeQuery’ will bring back lines that I have created in the VO and are held in cache? They must be held in cache else I would not be getting the error ‘Too many objects match the primary key’
Any guidance on this matter would be most appreciated,
Thanks
Mike

Answer 1

Unfortunately I do need to query the view again, each time the user clicks on a different ‘application’ in the train it will need to show only the lines in the view relating to that application. It is a bit like a master-detail except I want to show the detail lines on a separate page.
I could have made each page separately but I am trying to make it dynamic so if a new application is added in the future I only have to add the details to the database tables.
Thanks, Mike
