Java Development Tools

I have an ADF JSFF page.

It contains a drop down menu through which I could see details of a particular event b ased on the option selected in the dropdpwn choice.

<af:selectOneChoice id="socEventLevel"

                                    label="#{Msg.LOG_LEVEL}"

                                    value="#{pageFlowScope.ea_entUiModelBean.logLevel}"

                                    disabled="#{!pageFlowScope.ea_entUiModelBean.rowSelected}"

                                    unselectedLabel="#{Msg.SELECT_LEVEL}"

                                    valueChangeListener="#{backingBeanScope.ea_entEventLogTabUiBean.getLogDetails}"

                                 autoSubmit="true">

                  <af:selectItem label="#{Msg.VIEW_LOG}" value="0"

                                 id="si5"/>

                  <af:selectItem label="#{Msg.ERROR}" value="1" id="si4"/>

                  <af:selectItem label="#{Msg.WARNING}" value="2" id="si33"/>

                </af:selectOneChoice>

The moment I select one of these choices and try to navigate to another page I get a popup that says "This page contains uncommitted data. Would you like to perform navigation. Press OK to continue , or cancel to abort navigation"

How do I remove this popup ??

Thanks in advance
