EGL colleagues, share a solution found when using DynamicLoader.
My main application not carrying the other RUI's.
Placing the command "makeSureDojoIsIncludedInTheMainHandler DojoCheckBox {};" I solved my problem.
I did not quite understand why, but I believe it was the "import" of "dojo.widgets" that solved the problem, because my main application screen has not only control navigation among the other RUI's.
Success to all.
