Thanks Volker,
You're right.
"forceId" however, doens't go for "inputHidden" & "SelectOneMenu".
(TLD doc)
Yet, adding the "container IDs" to the JS call (getElementByID
('contID + ownID') ) makes it work. :-)
Have they ever thought of making a kind of cascading resolver to
solve issues like these?
(= following the ID-Tree of a page)
But I guess JS should have thought of that, not MyFaces... :-)
& Any idea for the first part of the question? Is such direct access
(by index) of ArrayList elements possible?

Hi Philippe,
To part B:
the generated html element ids are not the same as you set on the jsf
tags. I think this is the problem of your javascript.
This is not a bug! see http://wiki.apache.org/myfaces/forceId
If in doubt take a look into the generated html source for the ids.

Hi List,
I think I am stuck with a bug (B/) & I have a list-access element
question as well. (below: A/)
A/ As you will probabely wonder with the code below: what is this guy
trying to do with
these value="#{regcalbean.currentEvent.refDateDeltas[2]}" ??!
Well, I have an ArrayList and I wondered whether there is a way to
talking directly to an (Array -> indexed) element of this List.
Like you can talk directly to an array index in Java. (that's where I
stole the syntax)
I get no complaints, but... the List just doens 't get filled so this
must be wrong somehow :-)
I hope this is possible, if it is, a hint as to how to make this
work is
welcome! (I saw some methods smelling to what I want to do in a
property
resolver class, if I remember well, but I don't know how this
translates
into front-end access)
I know I can make it work by creating indirection-vars (one/list
element) but that i sobviously far less elegant than if this direct
access would be possible. (less memory, less redundancy, less
code, ...
and very intuitive)
B/
I think I came across a MyFaces-javascript integration bugs (at least
for 1.1.1 - donno whether it has already been mentioned or even
better,
corrected in 1.1.2!)
The error I got on several occasions, was a "/element has no
properties/" error, whereas the element surely had props.
*Example 1:*
To construct a (js-) popup with some explanantion, but taking into
account internationalisation (hard req), I made a hidden text field
holding the var for when the JS needed it.
So in the page has this js: (header)
function explainComplexData(){
var text = document.getElementById("justForJSPopup").value;
alert(text);}
& in the page itself: the img of a question mark which gives the
explanation when clicked upon:
<h:graphicImage
value="../pics/regCalNew/questionHelp.png"
onclick="explainComplexData()"/>
& a hidden input field, just as a headless container for holding the
explanantion in the correct language.
<h:inputHidden id="justForJSPopup"
value="#{labels.newCal_explainComplex}" />
This unfortunately does not work with MyFaces. (what made it work:
change the inputHidden to a POHO (Plain Old HTML Object ;-) but then
i18n goes thru the window and of course I prefer to stick to one
compontent flavor)
*Example 2:* when checking a checkbox, 2 menus ("menu3" & "menu4"
should
change their "disabled"-aspect.)
Setup: one checkbox to trigger this, one js to apply these changes and
of course the 2 selectMenus.
Code:
<h:selectBooleanCheckbox id="complexDeltaDateFlag"
value="#{regcalbean.currentEvent.refDateDeltas[2]}"
onclick="javascript:enableFocus()"/>
<h:selectOneMenu
value="#{regcalbean.currentEvent.refDateDeltas[4]}" id="menu4">
<f:selectItem ... (a few selectItems) />
</h:selectOneMenu>
& the js:
function enableFocus()
{
if(document.getElementById('menu3').disabled == true)
{
document.getElementById('menu3').disabled = false;
document.getElementById('menu4').disabled = false;
}
else {
document.getElementById('menu3').disabled =
true;document.getElementById('menu4').disabled = true;
}
}
... gives same error: the elements (menu3 & menu4 here) would have "no
properties"...
Frustrating!
