Radio button with two boolean choices
Hello. I know it's really simple but I cannot make it works.
What I want to do is to put a radio button with two options, in a form. The
attribute that will be set by selecting one of the two options is a boolean.
That's it, simpy a true/false choice.
1) Is it possible to declare a static list directly in the JSP without the
callback to the action to get a Map with such boolean values?
2)If it is not possible, how can I do that. I tried to put a
Map<String,Boolean> called options in my Action
and put that in the jsp:
<s:radio id="subChoice" labelposition="top" key="ManualUploadForm.6"
name="c_sub" list="options"></s:radio>
where c_sub is a the boolean variable I want to set by choosing an option.
It does not work.
In the log I get:
tag 'radio', field 'list', id 'subChoice', name 'c_sub': The requested list
key 'options' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
Please help. Thano you very much.

Probably because the "#" character is used by other ELs and most JSP editors
don't parse OGNL as its own EL, let alone its anonymous list creation syntax.
Most likely it's attempting to parse it as JSF or UEL.

Thank you very much. It works now. I tried it before, but instead of what you
suggested me I was trying with:
<s:radio list="#{1:'True', 0:'False'}" name="c_sub"/> and it didn't work.
Now it's ok. Only a question... your advice works but the jsp editor says
me: Syntax Error in EL. Do you know why?
<s:radio list="#{true:'True', false:'False'}" name="c_sub"/>
(the part in Bold is what the editor highlight as syntax error...)
Thank you

Yes it is. Have you tried something like this:
<s:radio list="#{true:'True', false:'False'}" name="yourFieldNameHere"/>?
