Passing Long value to rich:menuItem via f:param rounds and c

[apolyakov]

Hi All!

I'm quite a new to RF, so please don't kick me if I'm asking dumb questions.
I have encountered a strange problem - when I try to pass very long Long value to rich:menuItem component via f:param, I get incorrect (cut and rounded value). Here is the code:

<f:view>
 <h:form>
 <rich:contextMenu attached="false" id="menu" submitMode="server">
 <rich:menuItem immediate="true" action="#{testBean.someAction}">
 Download document <b> {name}</b> with id {currentDocId}
 </rich:menuItem>
 </rich:contextMenu>
 <rich:dataGrid value="#{testBean.objects}" var="item" columns="3"
 elements="9" width="600px">
 <h:panelGrid columns="1">
 <h:outputText value="#{item.name}, #{item.id}" />
 <rich:componentControl event="onclick" for="menu" operation="show">
 <f:param value="#{item.id}" name="currentDocId" />
 <f:param value="#{item.name}" name="name" />
 </rich:componentControl>
 </h:panelGrid>
 <f:facet name="header">
 <rich:datascroller />
 </f:facet>
 </rich:dataGrid>
 </h:form>
</f:view>

bean looks like:

@Name("testBean")
@Stateful
@Scope(ScopeType.SESSION)
@AutoCreate
public class TestBean implements ITestBean{
...
public TextObject[] getObjects() {
 TextObject obj = new TextObject();
 obj.setId(new Long("81022231438000081"));
 obj.setName("name 81022231438000081");
 return new TextObject[] {obj};
 }
}

I got the following result:
<h:outputText value="#{item.name}, #{item.id}" /> returns correct values:
"name 81022231438000081, 81022231438000081"
but in the menu item I receive:
"Download document name 81022231438000081 with id 81022231438000080"

Please help me, I'm completely stuck. Moreover, if I modify getId method to return id.toString(), everything is fine and everything also is fine if id is not that long.

Thank you in advance!

Sorry, forgot, RF version 3.2.2.GA, JSF version 1.2MR1

That's browser rounding occurs. Use toString() at the server side for correct representation.

Nick,

so no way to correctly pass Long as f:param?
Yes, using toString helps, thank you! but is it a good practice to have say 'getIdAsString' method in entityt bean just because of browser?

Or do you mean that I can use toString somethere "closer" to browser view?

Tahnks in advance!

Yes, in the view:

1. Kinda hack forcing conversion to string:

<f:param value="#{''}#{item.id}" name="currentDocId" />

2. Use JSTL trim or join functions
