binding select value to a Java 5 enum

Hi All,

I`m trying to bind the value of a select to an enum but I`m getting
the following error:

Invalid field value for field

Does anybody knows how can I set the value to be the enum type?

Thanks,
Daniel

That's a known limitation of the s:select tag, which only works with 
string-valued properties. The most straight-forward workaround is to set 
value, as in:

   <s:select name="property1" value="property1.toString()"/>

Hi Dave/All,

It worked fine even tough I had to put the fully qualified name of the field.

What is not working is when I post back to my JSP, the select field is
not automatically selected, as a workaround, I had to specify in the
value of the field a method in my action which tells what item is
selected. This way, it works fine.

Does anybody have an idea why?

Thanks,
Daniel

Does it work if you remove the "person." part? I'm
still not entirely clear why one of my current apps
does conversion correctly, but my -conversion file
only has the last part of the object graph in it.

Re: binding select value to a Java 5 enum

Hi All,

Per my message above I was able to set value for an Enum which is a
property of my action using a converter as in the showcase example,
but I was not able to set the enum to a nested, when the enum never
gets called.

My structure is similar to:

person.gender (where gender is an enum)

My conversion file is like this:

person.gender=mypackage.EnumConverter
Element_person.gender=mypackage.Gender

This way, the property person.gender is always null. Can somebody help me?

Thanks,
Daniel
