Hi
I am still (fighting) trying to display a radio button dynamically reading data
from a DB, but I get this error: javax.servlet.ServletException: No getter
method available for property control for bean under name
org.apache.struts.taglib.html.BEAN
This is the "route", code attached below:
1- userlogin.jsp link calls the method iniciarTest of the Dispatch_ActionTest
action
2- After getting the data in the action, LabelValueBeans are used to store the
data and pass this data as the request "choices" to desarrollarTest.jsp page
3- The request data ("choices") should be displayed in desarrollarTest.jsp as a
radio option with the value "bean:write..."
4- But this error appears -> javax.servlet.ServletException: No getter method
available for property control for bean under name
org.apache.struts.taglib.html.BEAN
What is wrong, or what should I check? Why the bean is defined like "name
org.apache.struts.taglib.html.BEAN"?
Any help will be so much appreciated.
Thanks.

No. What's the issue with indexed properties? They're the recommended way
to deal with indexed properties.
You could just do it by hand, tool.
