Reload the custom component through command button

Hi,

I have stuck in a more complex situation for the simple thing.

I have a component to construct the pageblock table , That component is called by command button in visualforce page my code is as below ....
Sorry in advance to show this big code...

VF Code :
========================

<apex:page controller="RetrieveArchivedRecords" sidebar="False">

    <apex:form id="theForm">
        <apex:commandButton value="displayTable" rerender="callComponent,thePgBlock" action="{!fetchData}" id="displayData"/>
    </apex:form>

    <apex:outputPanel id="callComponent">

        <c:DynamicObjectTable ObjectName="Case" rendered="{!showResults}"
            FieldsetName="Test" DetailFields="DetailFieldsSet"
            JSONData="{!GetJsonData}"
            Title="Archived Cases"
            TablePageSize="6"
        />

    </apex:outputPanel>


</apex:page>

Apex Code:
===============
From class i m sending the json data

My Component
==================

<apex:component controller="DynamicObjectTableController">

    <apex:attribute name="FieldsetName" assignTo="{!strFieldSetName}" type="String" required="true" Description="Fieldset name"/>
    <apex:attribute name="DetailFields" assignTo="{!innerFieldSet}" type="String" required="true" Description="Fieldset name"/>
    <apex:attribute name="ObjectName" assignTo="{!strObjectName}" type="String" required="true" description="Object name"/>
    <apex:attribute name="TablepageSize" assignTo="{!Pagesize}" type="Integer" required="true" description="Object name" default="10"/>
    <apex:attribute name="JSONData" assignTo="{!strObjectJSON}" type="String" required="true" description="data list"/>
    <apex:attribute name="Title"   type="String" required="true" description="Title of the pageblock table"/>



// If I remoce the above line the pagination is working good, but command button of visualforce is not taking the recent value (command button not working properly) and if I add the aboce code , the paginatin buttons are not working but the command button in VF page is working .

<apex:form >
            <apex:pageBlock title="{!Title}" id="thePgBlock">

                    <apex:pageblocktable value="{!DisplayedObjects}" var="r" id="ArchivedTableID">

Apex : how to remove selected items from selectlist ?

Hi,

For adding the item in a selectlist we do the following

for(String f : FieldLabels)
        {
             selectedFieldsList.add(new selectOption(f,f));

        }
and this works perfect.

Same way how to remove from the select list ? I dtried with the following things and got the errors

E.g : 1 : for(String f : selectedFields)
        {
             selectedFieldsList.remove(f);
        }
ERROR : Method does not exist or incorrect signature: [LIST<System.SelectOption>].remove(String)

for(integer i=0;i<selectedFields.Size();i++)
        {
                      selectedFieldsList.remove(selectedFields.Size());
        }
ERROR : LIST INDEX OUT OF BONDS

for(String f : selectedFields)
        {

           selectedFieldsList.remove(0);

        }

here the items are deleted but , if i select 5 random items to delete, it is removing first 5 items not the selected one.
