[Erel]

The error has nothing to do with B4XPages.

It looks like a custom view with the wrong package name. This is all that I can say based on the information you provided.

You probably need to delete it and add it again.

Thanks Erel!
yes, i have a my "custom view", but I do not understand why

solved with follow steps:

• rename folder "project" in "old project"
• create new folder "project"
• create a new project B4XPages
• from Internal Design Open & Save all "layout bjl" from "old project"
• from IDE "Add Exist Modules" copy all "B4J Modules bas" from "old project"
• update "B4XMainPage"
• small changes

and ,,,,, wow! There is no error!

Thanks teacher!
