How to make a field mandatory in JSPX page in ADF

In this scenario, we need to make <inputListOfValues> field as Mandatory, which means no NULL values are accepted and User cannot enter NULL value in the Field. We need to display an Error message when ever User submits the form without any value.

This solution works well with any field which accepts “required” property attribute.

So in my case I dragged and dropped the column from the data control as a LOV then the below code is added in the JSPX page –

                           <af:inputListOfValues id=”fiscalYear1Id”

                                                      popupTitle=”Search and Select: #{bindings.FiscalYear1.hints.label}”

                                                      value=”#{pageFlowScope.Bean.fiscalYear}”

                                                      label=”#{bindings.FiscalYear1.hints.label}”

                                                      model=”#{bindings.FiscalYear1.listOfValuesModel}”

                                                      required=”#{bindings.FiscalYear1.hints.mandatory}“

                                                      showRequired=”true” editMode=”input”

                                                      columns=”#{bindings.FiscalYear1.hints.displayWidth}”

                                                      shortDesc=”#{bindings.FiscalYear1.hints.tooltip}”>

                                  <f:validator binding=”#{bindings.FiscalYear1.validator}”/>

                                </af:inputListOfValues>

From the above code we have “required” attribute which is to make the field as Mandatory one. But this did not work in my case. So I have to modify the “required” attribute value from =”#{bindings.FiscalYear1.hints.mandatory}” to “true”.

                             <af:inputListOfValues id=”fiscalYear1Id”

                                                      popupTitle=”Search and Select: #{bindings.FiscalYear1.hints.label}”

                                                      value=”#{pageFlowScope.Bean.fiscalYear}”

                                                      label=”#{bindings.FiscalYear1.hints.label}”

                                                      model=”#{bindings.FiscalYear1.listOfValuesModel}”

                                                      required=”true”

                                                      showRequired=”true” editMode=”input”

                                                      columns=”#{bindings.FiscalYear1.hints.displayWidth}”

                                                      shortDesc=”#{bindings.FiscalYear1.hints.tooltip}”>

                                  <f:validator binding=”#{bindings.FiscalYear1.validator}”/>

                                </af:inputListOfValues>

 

 By this the the field became as Mandatory and it shows the below error message when the user submits with NULL value.

showRequired=”true” displays the ‘*’ before the field.
