JSF input element value leads to ui crash after page refresh

Question

I have a model for a ui mask of input fields. This model is rendered with ui:repeat. The model is grid oriented so there is a class SearchMaskRow which aggregates SearchMaskColumn. A SearchMaskColumn has a member Property which itself has a member value of type Object.

Here the important part of the iteration:

<p:panelGrid id="searchMaskFieldsStaticGridId" styleClass="searchMaskFieldsGrid"
    rendered="#{not curSearch.isClosable()}">
    <ui:repeat value="#{curSearch.getSearchMaskDescription().getRows()}" var="curRow">
        <p:row styleClass="searchMaskRow">
            <ui:repeat value="#{curRow.elements}" var="curElement">
                <p:column colspan="#{curElement.columnSpan}"
                    styleClass="#{curElement.isOfDataTypeStr('label') ? 'searchMaskLabelColumn' : 'searchMaskInputColumn'}">

                    <!--  label -->
                    <h:outputLabel value="#{curElement.property.getValue()} #{curElement.colonOnRightSide ? ':' : ''}" for="colInputTextId"
                        rendered="#{curElement.isOfDataTypeStr('label')}" />

                    <!-- date data type -->
                    <p:calendar id="colCalendarId" styleClass="searchMaskInputElement" value="#{curElement.property.value}"
                        rendered="#{curElement.isOfDataTypeStr('date')}" showButtonPanel="true" showOn="button"
                        pages="#{curElement.getCalendarPages()}" size="#{curElement.getWidthInCharacters()}" />

                    <!-- string and integer data type -->
                    <p:inputText id="colInputTextId" styleClass="searchMaskInputElement" value="#{curElement.property.value}"
                        rendered="#{curElement.isOfDataTypeStr('string') or curElement.isOfDataTypeStr('integer')}"
                        size="#{curElement.getWidthInCharacters()}" />

                </p:column>
            </ui:repeat>
            <ui:param name="unfilledColumnsCount"
                value="#{searchBL.determinedUnfilledColumns(curSearch.getSearchMaskDescription(), curRow)}" />
            <p:column colspan="#{unfilledColumnsCount}" rendered="#{unfilledColumnsCount gt 0}">
                <h:outputLabel value="" />
            </p:column>
        </p:row>
    </ui:repeat>
</p:panelGrid>

On first access of the ui all works. But if the page is refresh by clicking the browsers refresh button or submitting the url, I get the following exception:

Probably there is a problem with the submit of the values. But I debugged the Property.setValue(value:Object) method and there werecorrect objects set.

If I understand this exception correctly, the list of SearchMaskElements inside SearchMaskRow (which is curElement in facelet) is of type string. But I cannot imagine how this be. It is a List and also there is no set access to this list only read on iteration. SearchMaskRow even hasn't a setter setElements() to put the string inside. Someone has an idea? I have no clue.

I am using: mojarra 2.1.23 primefaces 5.1.12 de.odysseus.juel 2.2.6

The corresponding backing bean is absent in the question. Here, `javax.el.PropertyNotFoundException: /icarchive/sections/firstSearchTab.xhtml @30,95 value="#{curElement.property.value}": The class 'java.lang.String' does not have the property 'property'.` it states that `curElement` is a String type property (you are referring through the expression `#{curElement.property.value}` in `` and ``) and needless to say that the class `String` does not have a property named `property` defined/declared inside. — Tiny, Feb 26 '15 at 14:52
curElement is a class always of my own type SearchMaskColumn. This class has a member Property and a Property has a member with name value of type Object. So the value inside the Property can be a string, that's ok, but never can be SearchMaskColumn be a string. — opfau, Feb 26 '15 at 15:11
`curElement` is obtained from `#{curRow.elements}` which in turn is obtained from `#{curSearch.getSearchMaskDescription().getRows()}`. Are you sure that all of these expressions return a correct/desired type? The message symptoms clearly state that `curElement` is a String type object. Thus, you cannot do `curElement.property` because `curElement` does have `property`. (As a side note, you could achieve the same thing using other nice JSF/PrimeFaces iterator components such as ``, ``, `` etc instead of using independent ``). — Tiny, Feb 26 '15 at 15:29
Yes I am also very confused about this exception message too. curElement cannot be a string. I even have not a setter for it only a getter and I generate a list with generic type SearchMaskElement. But maybe there is another issue with my approach. The code I posted is inside a p:tabView in each tab. I have only one form for all tabs. This is probably wrong? — opfau, Feb 26 '15 at 15:42
It is legitimate to have that code inside a `` (nevertheless, I did not try a stray `` but this should not be an issue either way). Did you put the required logic inside `getRows()` here in this expression - `#{curSearch.getSearchMaskDescription().getRows()}`? If it is then, please consider moving it in its own place usually a method decorated with `@PostConstruct`, since getters are supposed to be invoked several times by nature. — Tiny, Feb 26 '15 at 15:51
What do you mean with required logic. #{curSearch.getSearchMaskDescription().getRows()} getRows is only an accessor for a List. Isn't that correct? — opfau, Feb 26 '15 at 16:18
It is correct. I asked just because many a times, people are seen implementing business logic incorrectly in accessor methods even though there is no special case to do so. — Tiny, Feb 27 '15 at 02:15
Ok thanks for your comments. But I don't know what is the problem in my case. Maybe this exception message is misleading and I have debug a little more. — opfau, Feb 27 '15 at 07:05
Isolate some portion of the code alternatively, even if careful debugging does not help. I had to do this several times in the past. — Tiny, Feb 27 '15 at 08:33
I already did this and identified that the nested ui:repeat inside dynamic tabs in tabView is the problem. Now I gave each tab a own form and leave the tabView formless to avoid form nesting. Also I changed some names of iteration variables defined with var. I do not know what exactly was the trick. Probably the forms, but now it is working as expected :) — opfau, Feb 27 '15 at 09:10

you must change the name of the variable "value", I think that there are a contribution between the attribut 'value' and your variable.

good luck

Tried it with a changed name without success. Same exception. If it is the name then the 1st rendering of the ui would probably also not work I think. – opfau Feb 26 '15 at 13:25
