Urgent Help Please, Suggestion Box

[ro86]

Hello All,

I am trying to create a dynamic list of input text fields, each one has a suggestion box :

<c:forEach items="${bean.inputList}" var="parameter">
                <h:inputText id="_${parameter.code}" value="#{parameter.value}"/>
                <rich:suggestionbox for="_${parameter.code}"
                                    var="result"
                                    nothingLabel="No data"
                                    selfRendered="true"
                                    ajaxSingle="false"

                                    suggestionAction="#{bean.autoComplete}">
                    <h:column>
                        <h:outputText value="#{result}"/>
                    </h:column>
                </rich:suggestionbox>
</c:forEach>

The list used in this loop is populated when the user selects an item from a drop down. So When the user change the selected item , I call rerender on the output panel that contains previous list :

My Problem is on rerender (on the second selection made by the user) I recive the following exception:

com.sun.facelets.FaceletViewHandler handleRenderException
SEVERE: Error Rendering View
javax.faces.FacesException: Component for target _1 not found in SuggestionBox j_1_sb

Actually the component doesn’t exist because user changes the selection and it will not be included in the new list, so why the suggestion component still there, shouldn’t it be removed?

Thanks

use a4j:repeat instead of c:forEach

Hi LLya, Thanks for your reply,

I tried using a4j:repeat but I faced a problem in the generated component ID.

For the same previous example using a4j repeate

<a4j:repeat value="${bean.inputList}" var="parameter">

                <h:inputText id="_${parameter.code}" value="#{parameter.value}"/>

                <rich:suggestionbox for="_${parameter.code}"

                                    var="result"

                                    nothingLabel="No data"

                                    selfRendered="true"

                                    ajaxSingle="false"

                                    suggestionAction="#{bean.autoComplete}">

                    <h:column>

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

                    </h:column>

                </rich:suggestionbox>

</a4j:repeat>

<a4j:repeat value="${bean.inputList}" var="parameter">

                <h:inputText id="_${parameter.code}" value="#{parameter.value}"/>

                <rich:suggestionbox for="_${parameter.code}"

                                    var="result"

                                    nothingLabel="No data"

                                    selfRendered="true"

                                    ajaxSingle="false"

                                    suggestionAction="#{bean.autoComplete}">

                    <h:column>

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

                    </h:column>

                </rich:suggestionbox>

</a4j:repeat>

I get the following error on page start:

com.sun.facelets.FaceletViewHandler handleRenderException

SEVERE: Error Rendering View

javax.faces.FacesException: Component for target _1 not found in SuggestionBox j_1_sb

When I tried to load the page without suggestion components I found that generated

component ids doesn't match the value given in the repeat tag , instead it was given a value like 'j_id40:0:_'

change to

                <h:inputText id="justPlainShortId" value="#{parameter.value}"/>

                <rich:suggestionbox for="justPlainShortId"
