RE: dataTable error message - Validation Error "_id49": Value is not a valid option.

[Dave]

Thanks for experiments. This seems a bug/defect. User need to know which row got a problem in a dataTable.

Assigning an id to fields inside a dataTable should work; they still are unique per row since the dataTable index is included in the actual id. The error messages still does not seem to work, however. This looks like a bug to me.

 

Here is an example. I have this form with a dataTable inside, which again contains a set of outputLabel/inputText pairs.

 

<h:form id="testForm">

      <t:messages/>

      <t:dataTable id="testTable">

            <h:column>

                  <h:outputLabel for="" value="Test label"/>

                  <h:inputText required="true" id="testField"/>

            </h:column>

      </t:dataTable>

</h:form>

 

If we look at the actual HTML code generated for a couple of rows, then we see:

 

<label for="">Test label</label>

<input id=" testForm:testTable_0:testField"

       name=" testForm:testTable_0:testField"

       type="text" value=""/>

<label for="">Test label</label>

<input id=" testForm:testTable_1:testField"

       name=" testForm:testTable_1:testField"

       type="text" value=""/>

 

Even if the ids in the label and the input field matches I still get the message ¡°Validation Error in testField¡± instead of ¡°Validation error in Test label¡±.

I tried outputLabel, but it still did not work.

 

<t:dataTable

           var="student"

           value="#{bean.students}">

    <h:column>

         <h:outputLabel for="" value="#{student.name}"/>

    </h:column>

    <h:column>

         <h:inputText id="score" value="#{student.score}"/>

    </h:column>

</t:dataTable>

 

All the validation error messages are using the same id "score".  when I tried to use student name as id,

 

<t:dataTable

           var="student"

           value="#{bean.students}">

    <h:column>

         <h:outputLabel for="" value="#{student.name}"/>

    </h:column>

    <h:column>

         <h:inputText id="#{student.name}" value="#{student.score}"/>

    </h:column>

</t:dataTable>

 

I got error message: id must start with letter/digit/_. Obviously id must be a constant and  can not be method binding. Any ideas appreciated. thanks.

Yes, that's why I suggested you'd be better off trying to use a label
and have the value bound to your row data instead. But I haven't
tried it.

Remember that components in your dataTable may represent multiple
rows, but every row is still represented by only one component. So
only by binding something to your backing data will you get different
behavior per row.
