si:selectItem error parsing

lowecg2004 Dec 10, 2006 5:26 PM

(Not sure I should be posting here for si:selectItem)

I just tried to download selectitems-1.1.1beta2.jar but I get the following exception when my page renders:

I got @SelectItems working okay with a regular <f:selectItems>. I'm using this with Seam 1.1 CR2, Facelets 1.1.11 and Trinidad components.

<tr:selectOneChoice value="#{orderStorageBean.mediaHardDisk}">
 <si:selectItems value="#{hardDisks}" var="hd" label="#{hd.name}" />
 <si:convertEntity entityClass="com.ripuk.model.MediaHardDisk" />
</tr:selectOneChoice>

Have I done something wrong or is this an incompatibility with Trinidad components?

Cheers,

Chris.

Sorry for the late reply.

I've put up a new version in which throws a more descriptive exception. Can you try it and if you are still stuck post the exception here?

http://wiki.jboss.org/wiki/attach?page=SeamSelectItemsNewDesign%2Fselectitems-1.1.1beta3.zip

It works well with Trinidad for me :)

Any pointers on what this might be?

For now outject using @Out not @DataModel. I'll make the next version DataModel aware.

Pete,

I'm getting the same error here, using you latest build (linked from this thread). However, I'm using an Enum.

Error is:

java.lang.IllegalArgumentException: selectItems' value="#{companyTypes}" must implement java.lang.Iteratable but it is null (null)

 <si:selectItems value="#{companyTypes}" var="companyType" label="#{messages[companyType.labelKey]}"

</h:selectOneRadio>

public enum CompanyType {

 BRANCH("Branch");

 private final String name;
 private final String labelKey;

 private CompanyType(String name) {
 this.name = name;
 labelKey = "label_companyType_" + name;
 }

 public String getLabelKey() {
 return labelKey;
 }

 public String getName() {
 return name;
 }

 public String toString() {
 return name;
 }
}

I just followed you wiki article and looked at the examples. Any idea what's wrong?

pmuir Dec 13, 2006 10:03 AM (in response to lowecg2004)
The clue is in the exception message. The el expression #{companyTypes} is resolving to null. To double check you can just write that to the page - e.g.

<h:outputText value="#{companyTypes}" />

Probably you've got something wrong with the bean that is outjecting it...

Hi Pete,

Sorry, I forgot to add that code to my OP. As far as I can see, this is just as you do in your examples. I tried adding an @Out as well, but the same thing happens.

@Factory("companyTypes") public List<CompanyType> buildCompanyTypes() { CompanyType[] companyTypes = CompanyType.values(); return Arrays.asList(companyTypes); }

krica Dec 13, 2006 10:28 AM (in response to lowecg2004)

Oh, forgot something else. When I debug that method, the array as well as the List is populated (not null). Also, for some reason, it is called six times!

Is the variable #{companyTypes} not null in other JSF components (h:outputText, ui:repeat for example)?

11. Re: si:selectItem error parsing

krica Dec 13, 2006 12:29 PM (in response to lowecg2004)

Well, nope, it was not.

This problem obviously stems from an apparent lack of understanding of the @Factory annotation. I looked at your examples and saw your factory methods not being accompanied by a property, but instead just returning the created lists. So I thought "well, that's cool, I don't need a property for this List". Alas, it did not work. Adding a "List companyTypes" property with an @Out annotation solved the problem.

Anybody care to educate me in why your example code doesn't need to do so?

The @Factory style outjection was introduced in 1.1 series (before it just had a void outcome).
