oracle adf - Two Criteria in on jsf page -

-

i have jsf page 2 query components following view criterias:

  • vc1 , 2 bind variabe a(required) , b,
  • vc2 , 2 bind variable c(required) , d

both applied same instance of viewobject , rendered property of both queries change pageflowscope parameter

when apply vc2 view criteria , press search button error appears: the attribute a(from vc1) required

whats solution?

required parameter required set, if not used.
so either have set value or remove require restriction.
in cases viewcriteria parameters shouldn't have require property set. , default behavior such parameters in 12c. assume using of 11g releases.


but may trying solve problem in wrong way? if case, give more details on problem, trying solve.
