Hello,
I have old customized CRM 4 based script for sub-grids, that creates dynamic fields and used for entering new data. Until UR12/13 it was working, but with CRM updates some field properties moved to html5 and all fields loosed all events and behaviors. Maybe anybody try create with javascript dynamic fields in iframe, such lookups, and work with standard XRM methods.
I looked some other solutions, there all functionality (number control, lookup dialog calling etc.) 100% realized manually.
I will know, is any possibility create runtime fields (Sys.Application._components) and link to iframe html structure?
