WidgetSet no working after Migration from 7.7.15 to 8.8.2

Vaadin 6 / 7 / 8

I get the following on :

“

Widgetset ‘com.mycompany.harpy.AppWidgetSet’ does not contain an implementation for com.vaadin.v7.ui.TextField. Check the connector’s @Connect mapping, the widgetset’s GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.
”

I have combed through the POM and nothing I can see.

This bizarre?

Thx Tatu!

I fixed the issue but it is not straight forward as the thread listed above. I had misssed "vaadin-compatibility-client" but i HAD TO REMOVE "@Widgetset("com.vaadin.v7.Vaadin7WidgetSet") from my UI implementation. Why I have no idea??

we need a detailed white paper on how the "AppWidgetSet.gwt.xml" works and interacts with the UI?

Thanksw again
