<b:selectOneMenu> Ajax response issue

[chsreedhar]

View has three <b:selectOneMenu> componets.

    <b:selectOneMenu d="pc" value="#{mcRequestBean.pc}" colMd="9" requiredMessage="Select Primary Category" required="true" labelStyleClass="required-pf" styleClass="selectpicker" process="@this" update="bc" label="Primary Category:" labelColMd="3">
           <f:selectItem itemValue="" itemLabel="--Select --" noSelectionOption="true" />
           <f:selectItems value="#{pCat.primaryCategories}" var="pc" itemLabel="#{pc.id} - #{pc.description}" />
    </b:selectOneMenu>

    <b:selectOneMenu id="bc" value="#{mcRequestBean.bc}" colMd="9" requiredMessage="Select Basic Category" required="true" labelStyleClass="required-pf" styleClass="selectpicker" process="@this" update="stc" label="Basic Category:" labelColMd="3">
       <f:selectItem itemValue="" itemLabel="--Select Basic Category--" noSelectionOption="true" />
       <f:selectItems rendered="#{not empty mcRequestBean.pc}" value="#{bCat.getBasicCategories(mcRequestBean.pc)}" var="bc" itemLabel="#{bc.basicCategory} - #{bc.description}" />
    </b:selectOneMenu>

    <b:selectOneMenu id="stc" value="#{mcRequestBean.stc}" colMd="9" labelStyleClass="required-pf" requiredMessage="Select Shape/Type Category" required="true" styleClass="selectpicker" onchange="ajax:mcRequestBean.prepareCurrent()" label="Shape/Type Category:" labelColMd="3" process="@this" update="pnlGrp, ftr">
        <f:selectItem itemValue="" itemLabel="--Shape/Type Category--" noSelectionOption="true" />
        <f:selectItems rendered="#{not empty mcRequestBean.bc}" value="#{shapeType.geShapeTypeCategories(mcRequestBean.pc.id,mcRequestBean.bc.basicCategory)}" var="sc" itemLabel="#{sc.shapeType} - #{sc.description}" />
    </b:selectOneMenu>

Each updates next one's options through Ajax, initially it works as expected and i can choose options as normally. issue raises if i want to change first or second option, i.e., if i change first #pc option, second one #bcvalue is not setting default.
Browser's response shows there are more than one options having attribute selected="true" in ajax response (file attached issue_selectone.txt)

My gut feeling tells me that's probably not a BootsFaces bug. In particular, the multiple selected options indicate your Category objects don't implement the equals method correctly (or something like that).

I suggest you debug the method SelectOneMenuRenderer.isSelected(). Most likely, you'll see it'll return true too often. This should help you to find out why it does that.

BTW, if I get you right, you expect the second combobox to show the empty default item after selecting a different item in the first combobox. However, I don't see why the second combobox should display something else. Is there some code you didn't show us? In particular, does mcRequestBean.setPc() modify mcRequestBean.bc? I can see the the list of option is updated, but the value as such remains unchanged.

For the sake of convenience, this is the method I suggested to debug:

	private boolean isSelected(FacesContext context, SelectOneMenu menu, Object value, Object itemValue,
			Converter converter) {
		if (itemValue == null && value == null) {
			return true;
		}

		if (value != null) {
			Object compareValue;
			if (converter == null) {
				compareValue = coerceToModelType(context, itemValue, value.getClass());
			} else {
				compareValue = itemValue;

				if (compareValue instanceof String && !(value instanceof String)) {
					compareValue = converter.getAsObject(context, menu, (String) compareValue);
				}
			}

			if (value.equals(compareValue)) {
				return true;
			}

		}
		return false;
	}

You are right, there were small invisible character entered in equals method. Thanks.

I suppose that means I can safely close the issue?
