Hi,
I have a requirement where I have a search box in VF Page which displays Contacts based on Search String. If there is only one record matches the string the page should automatically redirect to that Contact record.
I am using Page Reference and Param to get the Id from the Search String. But it's throwing an error says URL is broke.
//Controller

public class SearchContactsController {
    public List<Contact> conList{get;set;}
    public String search {get;set;}
    public String Id{get;set;}
    public PageReference contacts() {
        Id = ApexPages.currentPage().getParameters().get('id');
        conList = [SELECT Id, FirstName, LastName FROM Contact WHERE LastName =:search];
        if(conList.size() == 0) {
            ApexPages.addMessage(new ApexPages.message(ApexPages.Severity.ERROR,'No Records Found'));
        }else {
            if(conList.size() == 1) {
                PageReference pr = new PageReference('/'+Id);
                pr.setRedirect(true);
                return pr;
            }
        }
        return null;
    }
}

//VF Page

<apex:page controller="SearchContactsController">
    <apex:form >
        <apex:pageMessages />
        <apex:pageBlock >
            <apex:inputText value="{!search}" label="Search Contacts"/>
            <apex:commandButton value="Search" action="{!contacts}">
                <!--<apex:param name="id" assignTo="{!search}" value=""/>-->
            </apex:commandButton>
        </apex:pageBlock>
        <apex:pageBlock >
            <apex:pageBlockTable value="{!conList}" var="con">
                <apex:column headerValue="FirstName" value="{!con.FirstName}"/>
                <apex:column headerValue="LastName">
                    <apex:outputLink value="/{!con.Id}">{!con.LastName}
                        <apex:param name="id" assignTo="{!search}" value="{!con.Id}"/>
                    </apex:outputLink>
                </apex:column>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Can someone help me with what's wrong with my code. Thanks in Advance...
