Re: 'Simulating' commandLink from Javascript
I guess that'd be one work-around. I think in this case I'll be better off biting the bullet and creating a component. L.

Yes, but that is all really in the beginning, currently.

Re: Dojo integration (was "Re: 'Simulating' commandLink from Javascript'")
Our final goal is to get rid of prototype and use dojo instead as our base-library for AJAX. So we want to further AJAXify our component set with the help of dojo, and replace the existing implementations with dojo-functionality. The problem with prototype is lacking namespacing... regards, Martin On 2/3/06, Rogers Reilly <[EMAIL PROTECTED]> wrote: > Laurie Harper wrote: > > > Hmm, OK, thanks; that makes sense.

Laurie Harper wrote: Hmm, OK, thanks; that makes sense. So, it's either time to start wrapping Dojo widgets with JSF components, or time to learn about Shale's remoting features ;-) Picking up on this- I'm just about to refactor two Dojo/JSP projects (one work, one personal) into Dojo/Shale/JSF/Hibernate projects, and this sliver of the stack is exactly what I'm wrestling with. My first thought was to define a relatively narrow Dojo interface for thick client-side stuff (letting MyFaces do simple stuff like autocompletes), keeping the server fairly decoupled, but now I'm wondering if they can be wired more tightly. Somebody posted on the Dojo mailing list about weaving Dojo libraries into MyFaces ... it wasn't clear (to me, at least) whether this was just for the purpose of using it for behind-the-scenes utility functions, or for AJAX-ifying current JSF components, or for wrapping Dojo widgets as Laurie mentioned. Does anyone know where MyFaces is going in this regard? I expect at first I'll be doing a lot of hand-wired Shale remoting in widgets, but it'd be great to have some idea of where to expect "help" in the future. -Rogers

I have found that it is different for IE vs. Netscape/Firefox. I'm not
a js expert but it works.
This is how I invoke a hidden commandLink in a table row...
commandLink
function invokeRowLink(row) {
if (navigator.appName.indexOf("Netscape") != -1) {
invokeRowLinkNS(row);
} else {
invokeRowLinkIE(row);
}
}
function doClickNS(anchor) {
var evt = anchor.ownerDocument.createEvent('MouseEvents');
evt.initMouseEvent('click', false, true,
anchor.ownerDocument.defaultView, 1, 0, 0, 0, 0, false, false, false,
false, 0, null);
anchor.dispatchEvent(evt);
}
function invokeRowLinkNS(row) {
if (row.hasChildNodes) {
tds = row.getElementsByTagName("td");
for(x=0;x
