JSF doesn't know how to convert String to User as there is no converter been registered for User type, hence the error message which you got. You'd normally need to create a custom Converter for this, as explained in this answer, but based on the given Java code, you actually need #{usersDAO.selectedRole} instead which is already of String type. So you don't need to create a custom Converter. By the way, a managed bean with "DAO" in the name is quite strange. Are you sure that you aren't mixing concepts or tight-coupling different responsibilities in a single class (which would lead to poor reusability/maintainability)? share|improve this answer edited Jun 6 '12 at 17:07 answered Jun 6 '12 at 16:57 BalusC 681k20224662689 thanks. i found my mistake, i was using #{usersDAO.selectedUser} wrongly. i replaced it with #{usersDAO.select

JSF and other frameworks work with this type. Also, java.sql.Date extends java.util.Date but its purpose is basically for JDBC usage.

This Site Careers Other all forums Forum: JSF Data Table --> Conversion Error Occurred (!!!) Mike London Ranch Hand Posts: 1208 6 posted 10 years ago I have an updateable resultSet from a MySQL database displayed in a Data Table. The data type, in MySQL, for the checkbox column is currently smallint -- I've tried other data types as well (BIT, TINYINT, INTEGER...). On my JSP (JSF) form, I have a Data Table with a checkbox. If I check the check box and click Submit, my tag says: "_id33": Conversion error occurred. ================= The ResultSet is updateable. I created a boolean property with getters/setters in the Managed Bean. I've tried int, byte, and short also as data types for the property's getters/setters. The "Core JSF" book says (page 209) that the JSF implementation will do converters for you automatically for primitive types. ------------ I'm stumped!!! The error message is kind of helpful, but not helpful enough. I've tried changing the Managed Bean's property type, but it doesn't seem to be getting called anyway due to the "conversion error". There are lots of posts about this but for SQL Server, not for MySQL. =========================== Has *anybody* gotten this error and knows what I need to try next? This is incredibly frustrating. Thanks very very much for any ideas at all!!! -- Mike Gregg Bolinger Ranch Hand Posts: 15304 6 I like... posted 10 years ago The "Core JSF" book says (page 209) that the JSF implementation will do converters for you automatically for primitive types. All my research and experience suggests that if your data is of type int coming into the page, then the rendering type won't be able to be a boolean. The conversion from int to boolean needs to happen between the data layer and the model. But I am still looking into it to be sure.
