Mapping Date request params to component properties

[trouby]

Hello,

I have a simple class that inherits from 'EntityQuery',
Im trying to add restrictions that are based on params of 'Date' type,

Seems like it fails with a ClassCastException, it used to work in older versions of Seam (I currently use 2.1.0.SP1)

Here's the full stack:

Many thanks,

I don't see anything related to an EntityQuery in that stack trace.

[trouby]

I don't think it's related,
I think its just that Seam can't convert the date request parameter to the property,

Asaf.

[norman]

Can you explain exactly what you are doing then?

[trouby]

Simple,
I have an xhtml page with a search param:

<rich:calendar id="someDate" value="#{someList.item.someDate}"
locale="#{locale}"
popup="true"
datePattern="dd/MM/yyyy"
/>

my xhtml.page.xml file has:

param name="someDate" value="#{someList.item.someDate}"

my someList looks like:

@Name("someList")
public class SomeList extends EntityQuery {
private static final String[] RESTRICTIONS = {
"item.someDate >= #{someList.item.someDate }",

Submitting the form causes the exception,

But again, I think that this is not really related to the EntityQuery,
I think that this is only relevant to the fact that I am trying to bind a request param to a date class,

Maybe Seam/jsf (not sure) does not convert the string to the date object correctly,

Many thanks,

Asaf.

I use this:

@Name(app.dateTimeConverter)
@BypassInterceptors
@org.jboss.seam.annotations.faces.Converter
public class DateTimeConverter extends org.jboss.seam.ui.converter.DateTimeConverter {
       
        public DateTimeConverter() {
                super();
               
                setType(both);
        }

}

in xhtml.page.xml use converterId :
param name someDate value someList.item.someDate converterId app.dateTimeConverter

V.

[baspet]

I use this:

@Name("app.dateTimeConverter")
@BypassInterceptors
@org.jboss.seam.annotations.faces.Converter
public class DateTimeConverter extends org.jboss.seam.ui.converter.DateTimeConverter {
     
     public DateTimeConverter() {
          super();
          
          setType("both");
     }

}

in xhtml.page.xml use converterId :

param name=someDate value=someList.item.someDate converterId=app.dateTimeConverter 

V.

[trouby]

Yeah,

That solves the problem, I didn't know it's possible to specify a converter to the 'param' tag manually.

Many thanks,

Asaf.
