lookup field in wrapper class can not get value from vf page.

I have a wrapper class which have a boolean value for checkbox and an identifier class, in Identifier class, there is a lookup field attribute_value__c. It seems that I can not get the picked value for attribute_value__c field in controller, always return null value. any clues?

 <apex:pageBlockTable id="tblIden" value="{!IdentifiersList}" var="i">
                    <apex:column width="25px">                       
                            <apex:inputCheckbox value="{!i.selected}" />                               
                    </apex:column>
                    <apex:column value="{!i.identifier.Identifier_Type__c}" headerValue="Type"/>  
                    <apex:column value="{!i.identifier.name}" headerValue="Name"/>  
                    <apex:column >
                        <apex:facet name="header">Attribute Value</apex:facet>
                        <apex:inputField value="{!i.identifier.Attribute_Value__c }" rendered="{!IF(i.identifier.Identifier_Type__c='Attribute','True','False')}"/>                     
                    </apex:column>
                </apex:pageBlockTable>

Hi Jingli,

You mean value is not setting from vf page?

Is there is any required field which is not selected or are you using any jquery in page.

Thanks

I do not use any jquery, and there is no required field which is not selected. I have tried to use picklist instead of lookup. samething, always just return null.

I have tried the code below (use picklist instead of lookup )too, still not working.

The vf page portion is 

<apex:pageBlockTable id="tblIden" value="{!IdentifiersList}" var="i">
                    <apex:column width="25px">
                        <apex:actionRegion >
                            <apex:inputCheckbox value="{!i.selected}" >
                                <apex:param name="selectedIdenId" assignto="{!selectedItemId}" value="{!i.identifier.Id}"/>
                                <apex:actionSupport event="onclick" action="{!processSelect}" rerender="identifiers">    
                                    <apex:param name="selectedIdenId" assignto="{!selectedItemId}" value="{!i.identifier.Id}"/>
                                </apex:actionSupport>
                            </apex:inputCheckbox>
                        </apex:actionRegion>
                    </apex:column>
                    <apex:column value="{!i.identifier.Identifier_Type__c}" headerValue="Type"/>  
                    <apex:column >
                        <apex:facet name="header">Identifier Name</apex:facet>
                            {!IF(i.identifier.Identifier_Type__c='Attribute',i.identifier.Name,i.identifier.Special_Feature_Code__c + ' - ' + i.identifier.Name)}
                    </apex:column>
                    <apex:column >
                        <apex:facet name="header">Attribute Value</apex:facet>
                        <apex:selectList size="1" value="{!i.attValue}" rendered="{!IF(i.identifier.Identifier_Type__c='Attribute','True','False')}">
                            <apex:selectOptions value="{!i.valueList}"/>
                        </apex:selectList>
                    </apex:column>
                </apex:pageBlockTable>

The wrapper class is 

        public identifierWrapper(Boolean selected , ECMS_Identifier__c identifier, list<ECMS_Attribute_Value__c> vlist,String avalue){
            this.selected = selected;
            this.identifier= identifier;
            if (vlist!=null){
                valueList= new list<SelectOption>();
                for (ECMS_Attribute_value__c v:vlist){
                    if (String.isEmpty(attvalue)){
                        attValue=v.name;
                    }
                    this.valueList.add(new SelectOption(v.name,v.name));
                }
            }
            if (String.isEmpty(avalue)){
                this.attValue=avalue;
            }
        }
