Issue with Apex:outputlink and forced click

Problem:

I have a search field in the case view that needs to search and redirect to a 'full search' page when a users hits enter in the field.

The enter part isn't an issue, the issue is that since this is inside the case layout page, I can not use a commandbutton/ commandlink since if I do it would redirect to the page but it will show inline=1 in the URL and thus treat it as an inline page and hide the header/sidebar. If I use the output link it will go to the page and not add inline=1 in the URL and show the header. BUT if I use the outputlink, when I force a click on the button, it performs the method, but not the redirect, so it just sits there.

In my method I put in system.debug and watched the system log, it showed that it did reach the method and did what was in it, but once it got to the return part with the new page reference, it just didn't do it. If I were to physically click the button instead of having the event listener do a jQuery .click() it will refresh to the new page.

To make sure it was nothing on the page that was wrong, or to see if it was just an outputlink, I did a test page with just simple methods and nothing in it but the required for testing. First i tested the commandlink/commandbutton:

<apex:page controller="LinkOnClickCon">
<apex:includeScript value="{!URLFOR($Resource.knowledgeTicket, '/jquery-1.4.2.min.js')}"/>
<script type="text/javascript" language="JavaScript">
jQuery.noConflict();
jQuery(document).ready(function() {
jQuery('.searchtoolstextbox').keypress(function(e) {
	code = e.keyCode ? e.keyCode : e.which;
	//alert(code.toString());
	if (code.toString() == 13){
		e.preventDefault();
		if(jQuery('.searchtoolstextbox').val().length >= 3){
			jQuery('.fullsearchbutton').click();		 		
		}
	}			  
});
}); 
</script>
<apex:form id="form">
	<apex:inputText id="kbsearchtext" value="{!userkeywords}" styleClass="searchtoolstextbox" />
	<apex:actionRegion id="FullSearchActionRegion">
		<apex:commandlink id="btnFullSearch1" styleClass="btn fullsearchbutton" action="{!getactionTwo}" onclick="alert('I was clicked');" value="Full Search">
			<apex:actionSupport event="onClick" action="{!getactionTwo}" status="workstatus" />
		</apex:commandlink>
	</apex:actionRegion> 			
<apex:actionStatus id="workstatus" startText="working..." stopText="" />
</apex:form>
</apex:page>

and controller:

public with sharing class LinkOnClickCon {

public string userkeywords{get; set;}

Public pagereference getactionTwo(){
	system.debug('\n ACTION Two METHOD userkeywords: '+userkeywords+'\n The enter key was clicked and so this should now be called.');
	string kywrds = userKeywords; 
	if(kywrds == NULL || kywrds == ''){kywrds = 'keyword';}
	kywrds = EncodingUtil.urlEncode(kywrds, 'UTF-8');
	system.debug('\n\n METHOD getactionTwo() - keywords: ' + kywrds + '\n \n');
	PageReference ref = new PageReference('/apex/knowledge?keywords=' + kywrds );
	system.debug('\n\n METHOD getactionTwo() - pageRef: ' + ref.getUrl() + '\n \n');
	ref.setRedirect(true);
	return ref;
}
}

With the commandlink/command button it works, it redirects to the new page (but like I said earlier, if I use this in the case layout it will redirect with a URL pram of inline=1 witch is bad).

But if I switch the page to use a outputlink instead:

<apex:form id="form"> 
	<apex:inputText id="kbsearchtext" value="{!userkeywords}" styleClass="searchtoolstextbox" />
	<apex:actionRegion id="FullSearchActionRegion">
		<apex:outputlink id="btnFullSearch1" styleClass="btn fullsearchbutton" value="{!actionTwo}" onclick="alert('I was clicked');" >
			Full Search
			<apex:actionSupport event="onClick" action="{!getactionTwo}" status="workstatus" />
		</apex:outputlink>
	</apex:actionRegion> 			
<apex:actionStatus id="workstatus" startText="working..." stopText="" />
</apex:form>

And I hit enter in the field, nothing happens, it wont even see the string from the users input.

here is the system log:

But when I physically click the button it works, redirects to the correct page, and see's the users input text.

So is this a bug with salesforce?

I am not sure if this is a bug or expected behavior but you are in a bit of a pickle.

Just for grins, and I am almost positive this will not work;

change your PageReference code to this.

PageReference ref = Page.knowledge; ref.getParameters().put('keywords', kywrds);

Again I don't think this is going to help but it's worth a shot and it's a quick fix.

So I heard back from the salesforce dev team on this... and they gave me an 'answer' for one part of it... they say if you use apex:actionFunction vs using apex:actionSupport it will work.... and it does, sorta. If you use it in a stand alone VS page (not embedded inside a record view etc) it will load the pageref but if it is inside a record view like mine is, it loads the pageref but inside the iframe not the parent, like it does if you physically click the button...

So it works.... but still isn't the same behavior as a physical click.

the change looks like this:

<apex:outputpanel id="fullsearchbuttonpanel">
<apex:actionRegion id="FullSearchActionRegion">
<apex:outputLink id="btnFullSearch1" styleClass="btn fullsearchbutton" style="text-decoration: none;" value="{!fullSearchUrl}" target="_top" onClick="controller()">
<apex:actionFunction name="controller" action="{!getfullSearchUrl}"/>
Full Search
</apex:outputLink>
</apex:actionRegion>
</apex:outputpanel>
