I am getting this error in IDE for all projects which have clv in it.
B4XView is shown as B4XViewWrapper in pop up notification below.
xCLV online version in IDE is shown as 1.73 and current version as 1.73 even though forum version is 1.74.

on execution I get this error on application crash

Add a reference to XUI.

Add a reference to XUI.

Adding reference removes the IDE error, however, app still crashed on activity.loadlayout line with same error as shared in post.
Deleting and recreating the layout exactly as previous resolved the error.
Thanks
