I have an issue with my grid pane.
I want to have Strings in it but vaadin does not seem to accept this.
Do anyone knows why ?
I’m putting my code down here so it will be easier.

That type defines the overall type of the whole grid, not that of each column. If you only have String, the parameter above has to be a String but keep in mind this won’t be easy to maintain. Additionally the usage of the addColumn method is wrong, you don’t have properties

ok thanks I understand i’ll just create a new type by myself
