This is a helpful advice, I always use "name" explicitly. But in this
case this is not it. According to FormTag.java source code:
=== cut here ===
// Look up the form bean definition
FormBeanConfig formBeanConfig =
moduleConfig.findFormBeanConfig(mapping.getName());
if (formBeanConfig == null) {
JspException e = null;
if (mapping.getName() == null) {
e = new
JspException(messages.getMessage("formTag.name", calcAction));
} else {
e = new JspException(messages.getMessage("formTag.formBean",
mapping.getName(), calcAction));
}
pageContext.setAttribute(Globals.EXCEPTION_KEY, e,
PageContext.REQUEST_SCOPE);
throw e;
}
=== cut here ===
Here mapping != null, but mapping.getName() == null. And I don't
really know why.
Another interesting gotcha is that FormTag removes Constants.BEAN_KEY
from page context, therefore implicit references to outer form will
not work after inner form closes. I would suggest not to put one
html:form into another. But this should not be the reason for
Caroline's bug.

Since they are different forms and different beans, have you tried using
them in the same form but adding the html:select attribute
name="SelectUsersForm" ? That way it uses
SelectUsersForm.getSelectedUsers[i].isSelected() ? Example:
<html-el:checkbox name="SelectUsersForm"
property="selectedUsers[${idx.index}].selected" />
I've mixed fields from different beans inside of the same single form before
using the name=".." attribute without any problems (as long as my beans were
already instantiated). For fields from the default form (the one used by the
html:form action attribute) I didn't put the name="..." because it is
assumed but I did add name="..." when I wanted to "insert" other bean field
values into my JSP.
