Error after adding field to entity

dev11 Jun 10, 2009 9:23 AM

Hi. I am new in JBoss seam. I need help.

I created seam project, created tables, than with 'seam generate' created this beans, xhtml and etc. Thank I made some changes, it worked properly. I added a field
private Integer status;
added getter and setter to one of my entities and now the page can't be loaded, I get this error
javax.el.ELException: /WorkbookEdit.xhtml @87,62 value "#{workbookHome.workplaces}": Error reading 'workplaces' on type com.webbfontaine.workbook.action.WorkbookHome_$$_javassist_seam_4
stack trace is

javax.faces.FacesException: javax.el.ELException: /WorkbookEdit.xhtml @87,62 value="#{workbookHome.workplaces}": Error reading 'workplaces' on type com.webbfontaine.workbook.action.WorkbookHome_$$_javassist_seam_4

1. Re: Error after adding field to entity

I know it is sometimes hard to find the real error in the tons of lines, but this error is the most important one:

Caused by: org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter of com.webbfontaine.workbook.model.Workplace.status

It basically sys that you're reding the form field which must be transformed from Object to the proimitive, normally that works, but not when you have a null valuie, that can't be squeesed into a primitive. Do one of the following thing:

- Change the primitive type in your model to the Object version.Because you state that you have an Integer, but the error says that you're using a primitive, probably cause by AutoBoxing whitin the set/get methods (have you defined an return or set value of type int ??).
- Add validation, which should make it impossible to put a null value,
- Lead the value to an action bean and check there for null,
- et.

Check the setters/getters first I suspect that the error is there...

Success !

Thanks for your response, I found the solution, I changed the type to Integer, but I added annotation @Transient because the bean property is not mapped to the table's column.

...or update the database table so that the new column contains a default, non-null value
