I am glad to be of help.
I agree, a wiki entry would be good.
btw TR also stands for Turkey :P
Cheers,

Mert,Excellent explanation, thanks for your patience! The extra code that I was looking for was code that would be in the originating page, but I think you've explained that sufficiently now. I've implemented this and it appears to be working well. Perhaps such an example belongs in the wiki?Cheers,Tim

Subject: Re: Popup New Window with CommandLink onclick attributeHey Tim,
Actually that's all for passing parameters via URL between jsf pages. I commented your post below. Hope this helps.

The subject of my blog is about passing parameters with the URL so i focus on the target page to get the determined parameter.
Sorry if it became a little confusing for all. So here it is. :)
The parameter should be passed via URL like /faces/myPage.jsp?myParam=blahBlah. You want to open a custom sized window. so rewrite the url with the parameters in your jscript. You can also use _expression_ languages with the jscript so no need to worry here to populate the url.
--the resolver function is resolving the binding of the current (i.e., the new popped up window) page, but I need to use the value from the originating page. I don't understand how one does so from the originating page when you wish to create a popup.
param map is the key here. From the JSF Spec:
param: an immutable map of the request parameters. So all the parameters specified in URL can be accessed through this map.
Resolving an _expression_ like #{param.myParam} helps retrieve the value.
I would like to control the size of the popup, which appears only to be available if I open the window via _javascript_. That requirement aside, do you by any chance have a working example of a link opening a new window, first passing a value from one page to the next? This is not nearly as straightforward as I would expect.
Yes i've implemented this but all the code is also in the blogpost too.
add a property
add getter/setter and resolver method.
add a hidden field & bind the property to hidden field
and use the passed value like getMyParam().
thats all.
The website [1] below suggests using output link, but I'm not sure what they did to make it work (i.e., they call target="_blank", but I don't see them attempting to first bind a value as would be the case with a commandLink).
outputlink also renders a <a> tag for itself. So you can simulate a popup action like,
<h:outputLink id="linkRoller" value="#" href="" target="_blank" >http://www.jroller.com')">
<h:outputText id="popupText" value="my popup page"></h:outputText>
</h:outputLink>
with window.open command you can specify your window size.
Regards,
Mert

setting a value before the onclick method is called. Unfortunately,
although that explains why I cannot update a backing value via a binding
method before opening a new window, I still am at a loss as to how I can
in fact open a new window that is passed the current value of my
datatable row.
**Does anyone have an example where they generate a popup window and
pass a value for use by the new window? I do not understand how a
managed bean might be instantiated if I am submitting a form via
_javascript_, as explained below. Ideally, I'd like to simply have a
commandLink in my dataTable that I can use to open the new window, and
bind a value before the page in that window is actually executed.
I _have_ tried one thing that is similar a hack used for getting the
apache display taglib to work with commandLinks: In addition to
surrounding my JSF datatable with a form tag, I've included in that form
tag a standalone commandLink. I then call a _javascript_ method from the
datatable which sets the _link_hidden_ value of the form to the page I'd
like to open; I also set a dummy param value (I called it "id") like so:
<h:form id="myMainForm">
<t:dataTable value="#{pageFlow.dataList}" var="dbRow">
... Some table columns ...
<t:column>
<f:facet name="header">
<f:verbatim>Header Name</f:verbatim>
</f:facet>
<h:form>
<h:commandLink > value="#dbRow.cellValue}">
</h:commandLink>
</h:form>
</t:column>
... More columns ...
<t:commandLink action="" id="viewNewPageLink"
<f:param name="id" value="" />
</t:commandLink>
</h:form>
<script type="text/_javascript_">
function myJavaScript(cellValue){
var f = document.forms['myMainForm'];
f.elemnts['myMainForm:_link_hidden_'].value='myMainForm:viewNewPageLink'
;
f.elements['id'].value=cellValue;
f.submit();
}

this is because you are doing a "non-postback" request Phase 1
(RESTORE_VIEW) goes directly to Phase 6 (RENDER_RESPONSE)
you may take a look at [1]
