Built new project tonight...
administrator collection layout works as expected
for a new record => administrator item layout works as expected
save and close => returns to the administrator collection layout as expected

problem - when editing existing record
- select edit from administrator collection layout
In the Item Layout...
The ordering field displays => JError: Unable to load JDom class : JDomHtmlFormInputSelect
AND
The toolbar is missing ???

Have regenerated the sandbox build several times
Have deleted the table and recreated the fields and layouts
Have again regenerated the sandbox build after recreating the tables / layouts

(project => xxxxx_config)

Thanks in advance

Sorry for beiing long.

Fixed.
Please regenerate, or include the JDom missing files :
- html.form.input.select
- html.form.input.select.combo

JError: Unable to load JDom class : JDomHtmlFormInputSelect Error ?
