I am trying to enable inline editing for a grid of entity objects of type Issue. Each issue has a cause represented by the attribute issueCause of type Cause. When editing the row, I would like to display a combo box with a list of existing values. I believe I've done everything right except when I try to edit a row by double clicking on it, I get the following exception:
Caused by:com.vaadin.data.util.converter.Converter$ConversionException:Unabletoconvert value of type ...entity.IssueCause topresentation type classjava.lang.String. No converter is set and the types are not compatible.
I tried to set a converter on the column, the actual combo box but with now luck. Does anyone have an idea.
I found this example: https://github.com/KrishnaPhani/KrishnasSpace/blob/master/Vaadin/VaadinGrid/src/com/krishna/vaadin/grid/basics/AbstractGridView.java which is supposed to do exactly what I want. I followed it but it doesnt work for me and I always get the same error.
