Design Type Question
This isn't about MyFaces specifically so I apologize but this list is the
best JSF resource I know of. ;)
I have a page that contains a list of Articles. There are also filter
criteria to filter the list of Articles. The article list is a dataTable
who's value is a method in the backing bean that returns a list of
articles. Simple enough. So when the page first loads, I get all the
articles.
The problem I am facing is part of the filter is 3 levels of categories.
Category, Sub Category, and a Sub Sub Category. Each of these is a
selectOneMenu and the child catagories depends on the parent category. So I
have valueChangeListeners registered so that when one drop down changes, the
child dropdown gets new values.
The problem with this is that when this happens, my method to get the list
of articles is called. But I don't want this to happen until I click the
Search button. So I am just looking for solutions to solve this.
Thanks.

Option #1 sounds good. Thanks.

Re: Design Type Question

Your backing-bean method is request or session scoped?
1) With request-scoped bean, I would set the value binding of your
filter components to a different bean property than the one that is
used by your "getArticles" method, and create a method "applyFilters"
that simply copies the "temporary" filter properties in the actual
ones.. this way your filters will not be applied until your "apply
filters" button is pressed.
2) With session-scoped bean, I would simply not get all the articles
on each "getArticles" call.. this method should simply return a member
variable, and a different method "applyFilter" should load its value,
looking at the current filter settings.
Hope this helps

You need to set escape="false" on the outputText so the text does not get
escaped.

Thanks Julian. *Unfortunately* I'm well adapt at Javascript so I already

Aside from a custom component, I'd assume I need to do something like that.

Thanks Julian. I will add it to the wiki when I get it finalized. I am
running into another issue of the selected value needing to be the
selectedIndex when an actionEvent occurs and the same page is displayed
again.

How are you loading the JS and performing the initialization? onload event
or appending to the window.onload?

And I am getting document.getElementById("catSelect") has no properties

This isn't about MyFaces specifically so I apologize but this list is the
best JSF resource I know of. ;)
I have a page that contains a list of Articles. There are also filter
criteria to filter the list of Articles. The article list is a dataTable
who's value is a method in the backing bean that returns a list of articles.
Simple enough. So when the page first loads, I get all the articles.
The problem I am facing is part of the filter is 3 levels of categories.
Category, Sub Category, and a Sub Sub Category. Each of these is a
selectOneMenu and the child catagories depends on the parent category. So I
have valueChangeListeners registered so that when one drop down changes, the
child dropdown gets new values.
The problem with this is that when this happens, my method to get the list
of articles is called. But I don't want this to happen until I click the
Search button. So I am just looking for solutions to solve this.
Thanks.

No if you use selectOne components which update the backingbean. Your JS
should reference the selectOne components via ids - you might have to pass
dummy select items but these will get removed then replaced by the JS as it
loads. Remember that the page is rendered before its loaded by the browser
so the JS will execute after the rendering has been performed.

Ok, got it working now. One final question. If I do this with Javascript, I
am going to have to do all the work of updating the model with the new
values since it's client side, correct?
Maybe this should be my first custom component. Eh? lol.
Thanks for the help.

Re: Design Type Question

Alright, maybe a stupid question...
For testing I have a property in my backing bean called javascript with
getters and setters. I have initialized javascript with the following:
private String javascript = "<script type=\"text/javascript\">function
testFunction(){ alert('this is a test'); }</script>";
And then did:
t:outputText value="#{ArticleListBean.javascript}"/>
But it's not spitting out the code. Am I doing this wrong?
Thanks.

Another way to populate Javascript arrays with data from a jsf backing bean.
<script language="JavaScript">
var myJavaScriptArray = ${sessionScope.myBackingBean.myValue};
</script>
where myBackingBean is the name of the backing bean, change sessionScope to
requestScope if myBackingBean is request scope. The call to
sessionScope.myBackingBean does not initialize the myBackingBean, so
myBackingBean must already "be there".

Make sure to use forceId on the select items so the JS can find them
otherwise you will have to prefix the component ids with "formname:"

Julian,
Thanks for the suggestions. How would I go about populating javascript
values with data from the backing bean if I were to go with [1]? Any links
with this info?
Thanks.

[1] Use client-side population of teh drop downs
[2] Use 2 backing beans, 1 for the drop down and 1 for the articles. Lazily
load all getters. Use t:saveState to store the filter bean.
[3] Use Ajax

This isn't about MyFaces specifically so I apologize but this list is the
best JSF resource I know of. ;)
I have a page that contains a list of Articles. There are also filter
criteria to filter the list of Articles. The article list is a dataTable
who's value is a method in the backing bean that returns a list of articles.
Simple enough. So when the page first loads, I get all the articles.
The problem I am facing is part of the filter is 3 levels of categories.
Category, Sub Category, and a Sub Sub Category. Each of these is a
selectOneMenu and the child catagories depends on the parent category. So I
have valueChangeListeners registered so that when one drop down changes, the
child dropdown gets new values.
The problem with this is that when this happens, my method to get the list
of articles is called. But I don't want this to happen until I click the
Search button. So I am just looking for solutions to solve this.
Thanks.

Thanks Julian. *Unfortunately* I'm well adapt at Javascript so I already
know how to do that. What I don't know is how to populate Javascript arrays
with data from my backing bean.
Aside from a custom component, I'd assume I need to do something like that.
Thanks.
