Error Code JBO-25003

Question

Hi,
Jdevloper Version used : 11.1.1.4.0
Requirement: Creating dynamic ViewObject at runtime and Loading the data inthe tabe using for each statement. Dynamic ViewObject Creation will be based on the programmatic ViewObject used in the Screen. This dynamic ViewObject should get created on button action.
Method: By Using "CreateViewObjectforDef", dynamic ViewObject getting created. Neccessary Iterator Entry for this vo is there in the page def.
issue: While loading the screen, iam getting the error as JBO-25003 Saying that "Object DynamicVO of type View Object not found". but when clicking the neccessary for displaying this VO it is working. Sorting too working.
if iam create dummy viewobject with this viewObject name before loading the screen, iam not getting this error. but sorting is not working. Error is getting displayed as "Attribute of type XXX is not found in the viewObject".
Any solution would be appreciated.
reg,

The basic point here is that, when you run a page, as part of model initialization for the page, run time may tries to access the VO(execution will be deferred though). In your current implmn AM::findViewObject('DynamicHistoryVO') returns null which may result in the exception you are seeing.
Two possibilities
1. Decide a default History VO based on your business use case
2. Defer the VO execution till user clicks on the History by moving the pop up content as a bounded task flow(use 'run as dialog' option to invoke task flow). Let the taskflow's init method build VO based on the input parameters
