Hello,
I have a Struts 6.4 page with a select, and I have a problem populating the
list attribute.
<s:select id="searchView_showSecured" data-mdb-select-init=""
name="searchView.showSecured" theme="simple" list="yesNoAllList"
listKey="id" listValue="label" />
What I'm trying to do is relatively simple: I have the following action code:
public class MachineParameterOverviewBootstrapAction extends
OverviewActionSupport implements Expirable {
...
}
And this is the super action. Notably, this getter does NOT have an underlying
field property.
public class OverviewActionSupport extends BaseActionSupport {
...
public List<SelectOptionView> getYesNoAllList() {
return
BootstrapSupport.getInstance().getYesNoAllList();
}
}
In the Tomcat log, I get this error:
Caused by: tag 'select', field 'list', name 'searchView.showSecured': The
requested list key 'yesNoAllList' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]

I assumed that Struts 6.4 would use getters and setters to interact with
properties on the page, because AFAIK that's what it did in Struts 2.3 and 2.5,
and hence I could just use a getter without having a field property with the
corresponding name on the action. Is that assumption incorrect?
For completeness, this is BootstrapSupport.java:

CustomMessageResourcesFactory().createInstance(getClass(),
this);
private List<SelectOptionView> yesNoAllList;
private List<SelectOptionView> yesNoList;
public static BootstrapSupport getInstance() {
return INSTANCE;
}
