ClassCastException in converter when Hiding / Showing unselected selectOneRadio
------------------------------------------------------------------------------- Key: MYFACES-1891 URL: https://issues.apache.org/jira/browse/MYFACES-1891 Project: MyFaces Core Issue Type: Bug Affects Versions: 1.2.3 Environment: MyFaces 1.2.3, Spring WebFlow 2.0.2, RichFaces 3.2.1, Tomahawk 1.1.6, Facelets 1.1.15.B1, Tomcat 6.0.16 Reporter: Patrick Schmidt See the attached example. When the block with the selectOneRadio ist shown, then hidden and then shown again a ClassCastException occurs in the Converter. The selectOneRadio has as submittedValue org.apache.myfaces.shared_impl.renderkit.RendererUtils$1, for which the conversion is done. javax.faces.FacesException: Exception while calling encodeEnd on

[jira] Commented: (MYFACES-1891) ClassCastException in converter when Hiding / Showing unselected selectOneRadio

I've attached a patch that fixes this. Christian is right, it is rooted in the handling of RendererUtils.NOTHING. The patch I've provided adds the code below to the beginning of the getConvertedStringValue() method of RendererUtils. + if (RendererUtils.NOTHING.equals(value)) { + return ""; + } + if (converter == null) { if (value == null) { return ""; The idea of this fix is partly from the patch Christopher Pierce provided for MYFACES-1567. Although, here, the check for NOTHING should be outside the block where converter is checked for null. The second fix provided in my patch is: public static final String SELECT_ITEM_LIST_ATTR = RendererUtils.class.getName() + ".LIST"; public static final String EMPTY_STRING = ""; - public static final Object NOTHING = new Serializable() {}; + public static final Object NOTHING = new Serializable() { + public boolean equals(Object o) + { + if(o != null) + { + if(o.getClass().equals(this.getClass())) + { + return true; + } + } + return false; + } + }; The NOTHING object has to have a modified equals() method to return true as long as the object is of the same class. Without this modification, RendererUtils.NOTHING.equals(value) is never satisfied since 'value' is a field of a Component that gets serialized/deserialized along with the UIViewRoot in JspStateManagerImpl. If it gets serialized and deserialized, regardless of server or client state saving method, 'value' will be a new instance and RendererUtils.NOTHING.equals(value) will return false. You can also observe this when using SelectOneListbox. Tracing through the code, you can see that in HtmlRendererUtils.getSubmittedOrSelectedValuesAsSet() Line 365: else if(org.apache.myfaces.shared_impl.renderkit.RendererUtils.NOTHING.equals(lookup)) { lookupSet = Collections.EMPTY_SET; } else { lookupSet = Collections.singleton(lookup); } the 'else if' condition will never be satisfied even if nothing is selected in the selectOneListbox. This is because lookup is of another instance that came from serialization/deserialization of the RendererUtils.NOTHING object. Therefore, lookupSet will never be the EMPTY_SET. Instead, it will be a collection containing the single element RendererUtils.NOTHING. Although this makes the code only marginally slower, I think it's still best to fix it. I've also tested SelectOneListbox and SelectManyCheckbox if they experienced problems when nothing is selected. But I've encountered no bugs when testing them. > ClassCastException in converter when Hiding / Showing unselected selectOneRadio > ------------------------------------------------------------------------------- > > Key: MYFACES-1891 > URL: https://issues.apache.org/jira/browse/MYFACES-1891 > Project: MyFaces Core > Issue Type: Bug > Affects Versions: 1.2.3 > Environment: MyFaces 1.2.3, Spring WebFlow 2.0.2, RichFaces 3.2.1, Tomahawk 1.1.6, Facelets 1.1.15.B1, Tomcat 6.0.16 > Reporter: Patrick Schmidt > Attachments: example.zip, RendererUtils.patch > > > See the attached example. > When the block with the selectOneRadio ist shown, then hidden and then shown again a ClassCastException occurs in the Converter.

'Show' : 'Hide'}" action="#{hideShowBean.toggleHideShow}" immediate="true" /> <t:div id="hideableBlock" rendered="#{!hideShowBean.hidden}"> <div><h:selectOneRadio id="selectOneRadio" value="#{hideShowBean.property}"> <f:selectItem itemLabel="Option Z" itemValue="" /> <f:selectItem itemLabel="Option A" itemValue="1" /> <f:selectItem itemLabel="Option B" itemValue="2" /> <f:selectItem itemLabel="Option C" itemValue="3" /> </h:selectOneRadio></div> <div><h:inputText id="inputText" required="true" /></div> </t:div> <h:messages /> </h:form> According to the spec (see MYFACES-1759), itemValue="" is equivalent to null, so when you hide and show several times, the result should be the same (Option Z selected). To be according to the spec, on myfaces core 1.2 RendererUtils.NOTHING should be removed and used null instead. But on myfaces core 1.1 this spec does not enforce us, so to remain compatibility this solution is acceptable.

This was the behavior: Option Z was selected by default. Pressing hide/show does not throw exception and will still select Option Z. If I select option A, B, or C and then press hide/show, it will still be the same button selected once the page loads. I also testd it with the patched jars (MyFaces 1.2.4-SNAPSHOT). Same behavior as above. I also tested for the case where your SelectItem gets created in your bean like: new SelectItem(null, "Null SelectItem", "This is a null select item.") The outcome is the same as your scenario. The item with the null value gets selected by default. When this selectItem gets rendered, the value attribute of its input tag is equal to "". I think there's nothing wrong with your scenario. Unless this is not the desired behavior. As for JSF 1.2 Spec item #69: 69 - Permit the passing of a null value to SelectItem.setValue(). RenderUtils.NOTHING only gets assigned to the value attribute of your UISelectOne or UISelectMany(in in the example given, it is assigned to HtmlRadioRenderer). I believe it does not get assigned to the value of SelectItem. I think that the only way to have the value of your SelectItem to null is by creating it this way: new SelectItem(null, "Null SelectItem", "This is a null select item.") Because if you use the tag similar to this: <f:selectItem itemLabel="Option Z" itemValue="" /> it will set the value of your SelectItem to "". In either case, during the update values phase, bean.property will be set to 0 and not null. Is the JSF 1.2 spec trying to say that whenever a SelectItem of value equal to null gets selected, the backing bean property should be null instead of 0? Also, the patch I provided here before was for RendererUtils which belongs to myfaces-shared-core. myfaces-shared-core is shared between myfaces 1.1 and 1.2 right? Or is there a way to modify RendererUtils without affecting myfaces 1.2 if we are to patch myfaces 1.1 only? > ClassCastException in converter when Hiding / Showing unselected selectOneRadio > ------------------------------------------------------------------------------- > > Key: MYFACES-1891 > URL: https://issues.apache.org/jira/browse/MYFACES-1891 > Pro |
