Html 5 placeholder attribute and jsf 2.0???

Hello,
I need to use the html 5 placeholder attribute together with jsf 2.0. I noticed this is not included in the attribute for the jsf inputtext tag.
Is there a way to circumvent this problem with jsf 2.0?
Thanks in advance,
J.

HTML 5 is in use and supported right now. That is not a reason to adopt an incomplete technology, that is only technology going yet again too fast for its own good. Do we really need a repeat of years of browser incompatibility problems?
Asking a web based programming platform to realize that HTML is constantly in fllux and allow for the ability to add tags and attributes as needed is not unreasonable. It's unreasonable that JSF wasn't built with that in mind to begin with.JSF already allows that. They are called 'custom components' and frameworks like Richfaces and Primefaces are full of them. Core JSF is only the minimal framework specification and should stay as small and flexible as possible.

We've run into this same predicament. We're trying to write a progressive, modern mobile device interface and we're constantly running into JSF restrictions.So perhaps you shouldn't have used JSF, eh? It makes little sense to blame everything on the framework, you simply used the wrong tool for the job. Now all you can do is live with the consequences, or do a migration to a technology more suited to your needs.
A decent web based programming language shouldn't have any say over the HTML. That should be fully modifiable by the developer. Then use a framework that is designed around this very concept. Play framework, Wicket, ... JSF is a stateful component based framework which was initially designed to not be anchored to a single markup format - hence it is as far away from the HTML/javascript as is possible. The fact that there is really only one choice of renderer at the moment is besides the point.

CR Reports 2008: Space Between HTML Attribute and Value Causes Attribute To Be Ignored

I have a field in a report with its Text interpretation set to "HTML Text". When content is rendered in that field that was sourced from a Microsoft Word document, some of the attributes seem to be ignored by Crystal.
For example, I have observed with "style" attributes that if there is a space between the attribute and the value, e.g. "FONT-FAMILY: SimSun" then Crystal will not render the Asian characters, replacing them with squares. However, if I manually remove the space so that the attribute appears as "FONT-FAMILY:SimSun", then the characters properly render as expected. I have observed the same issue with at least one other attribute as well, "FONT-SIZE".
This html does render properly in various browsers, so it seems to be an issue with Crystal Reports. Can you provide me with information about this and if there is a fix for it in subsequent versions. The version I tested with is 2008 - 12.5.0.1190.
Thanks for any assistance that you can provide.

hi Ethan,
here are the list of supported html tags in text interpretation...font family is indeed a supported tag.
does the html appear properly in the designer?...you mentioned various browsers and am wondering if you mean the crystal web viewers?
if the issue is in your cr designer, you may wish to patch it to the latest level.
also, ensure that you do not have any unsupported tags in your html that may be causing an issue.

Mixing Html and JSF

Hi,
I have a very simple question concerning a good jsf programming style:
Often I get Html pages from designers in order to put the necessary
jsf-code in it in order to get the application work.
So do I have to replace all html-code with jsf-tags or is it ok when
I only put jsf-tags where it is necessary (eg. where I have to output
some data from a bean etc. ).?
Thanks for your comments,
Andy

In general, if there are ways to accomplish the markup you want with JSF component tags (either standard ones, ones you write yourself, or ones written by third party component library providers), I believe that pages composed purely with JSF components will be more maintainable in the long run. In addition, you have the potential ability to use a different renderkit to output a different sort of markup, wihtout doing anything more to your pages than changing the URI of the tag libraries in use (and even that can turn out to be a one-place change if you're using something like a JSP 2.0 prelude file that is automatically included on every page).
That being said, there will be times when you absolutely, positively, have to include some raw HTML markup along with JSF component tags. Although this works pretty well in simple cases, there are lots of scenarios where it is problematic. However, there is a standard means to deal with this problem -- just enclose your raw HTML markup in an <f:verbatim> tag, and it becomes a JSF component that plays nicely with other JSF component tags, in every scenario.
I recommend that anyone planning on intermixing raw markup with their JSF component tags should plan on enclosing it in <f:verbatim> tags, to avoid interoperability problems.

Mixing HTML and JSF or better pure JSF Tags?

I'm relatively new to JSF, but i can say, i work with all the Web Standards in HTML and CSS.
So the HTML Render Results of JSF may not fit into a Web Developers Dreams of perfect HTML/CSS.
An Option i see is to use HTML and put only the dynamic parts in there as JSF Components.
What are the Pro's and Con's using HTML?
some stuff i can image:
Using pure JSF:
- May many components have impact to the performance?
- Mixed with HTML: What if the application should be rendered to another client pc (e.g. Mobile)?
What are your experiences?

The one downfall of mixing html with jsf, unless you use the f:verbatim tag, that the page is not properly represented in the component tree. Also depending on certain technologies you use (when I used ajax4jsf it worked this way) that the jsf component tree was rendered and then all the html was rendered at the end. This caused html tags and text that I had inside a jsf tag to be improperly displayed.
This though was the case when I was originally using jsf 1.1, so it may have been improved in later editions, but since I have become accustomed to writing the entire page in jsf tags I have not really tested that limit in the current version.

ID attribute in JSF components

Hello,
I have a question about the id attribute on JSF 2 components.
The document says, that it should be a String. Does that mean
String constant or could it also be a el-expression resulting to a String.
Actually I can use el-expression for id, but am not sure because of the documentation.
Any infos about that would be great!

Well, I stick with documentation. This is a specification. That means other iplementations like Apache myFaces
will also stick to the documentation not for current mojorra implementation or others.
That means, an implementation must not evaluate an el-expression. We ar here talking about evaluationg an
el-expression and the documentation says, that id must not evaluate el-expressions. At least thats what i understand.
So when i use mojorra and use el-expressions fpr id and change to apache implementation of jsf, i might be
not working.
Also i would get same result, if mojorra implementation someday does not evaluate el-expressions.
So it is very important for me and i guess for JSF to clear this point cause it is important for development.
One of the posters above mentioned it, is it possible to set dynamic ids for components or not.
I always read that it is not wanted. Ids will be generated. But you can give a component an constant id.
Like you can easy read in the documentation.
You are interpreting the documentation. But JSF is a specification and should not let room for interpretations.
If el-expressions are allowed it should be it should be documented.
By the way, I think in apache implementation of JSF, el-expressions for id is not allowed.
See here:
http://www.mail-archive.com/[email protected]/msg20800.html
So this implementation does exactly what documentation is saying so for me, mojorra implementation has here a bug!

Rendered attribute and actions

If a component has rendered set to false, can it still perform an action? In other words, if I have a button which does something which I don't render for unauthenticated users, is there any way they will be able to save the html to disk, and modify the various form elements to perform that unauthorized action?

@RaymondDeCamo
I understand that this is true for most languages eg. PHP, however I was wondering if the server would still execute the action if the button that was bound to it had its rendered attribute set to false. It seems like the JSF people would put in that kind of functionality. In other words, are you sure JSF doesn't run the server-side checks itself?
@BalusC
I know the person won't be able to click on the button, but could they add in their own custom HTML into the form to perform the action?

How do I pass input values from a html page to a jsf page

hi,
In my project,for front view we have used html pages.how can I get input values from that html page into my jsf page.for back end purpose we have used EJB3.0
how can I write jsf managed bean for accessing these entities.we have used session facade design pattern and the IDE is netbeans5.5.
pls,help me,very urgent
thanx in advance

Simplest way is to rewrite html page into jsf page.
You can use session bean in your managed bean like this:
import javax.naming.Context;
import javax.naming.InitialContext;
public class ManagedBean {
private Context ctx;
private Object res;
// session bean interface
private Service service;
          public ManagedBean() {
            try{
                 ctx = new InitialContext();
                 res = ctx.lookup("Service");
                 service = (Service) res;
           catch(Exeption e){

Page HTML Body Attribute - can there be more than one in this area?

In "Oracle Database Application Express Advanced Tutorials", Release 3.0, B32469-01 on page 10-10, in the section labeled "Create a Call to the disFormItems Function" in step 6........it reads:
//start citation
In the Page HTML Body Attribute, enter the following:
onload="disFormItems(); first_field();"
//stop citation
My questions are:
Can there be more than one "onload" statement?
If yes, how do you string them together?
Assume the second function I want to add is "disFormItems_local()"
Thank you,
Maggie

Okay, I have figured it out, I believe. So, I will provide my own answer in case someone else is looking for this type of situation in the future.
I edited the page definition by adding another function, disFormItems_local(), to the HTML Header Attribute.
Next, I edited the item's HTML Form Element Attributes to call the function, onchange="disFormItems_local()"
Then, I created a call to the disFormItems_local function in the page HTML Body Attribute, onload="disFormItems(); first_field(); disFormItems_local();"
Other stuff that you will need to know is to be found in Chapter 10 page 8, Enabling and Disabling Form Elements of the 3.0 Advanced Tutorials.

Use of the block quote element can cause ePubecheck to give the error "text not allowed here". Text must not be alone inside of a body tag and if it is not enclosed in some other block level tag, this may lead to the error you are receiving.

How to access custom property for attribute and control in .vm file?

Hi,
I have created custom properties in OPM for attribute and apply also that properties to attribute.
But if how to access that value in .vm file?
I accessed using
$attribute.getProperty("ScreenProp", "default value")
but it's not working but same is worked for screen custom property

$control.getProperties().get("PropertyName") works for custom properties on a control
If you output $control and $control.getProperties() to the html you can lookup the API for the used classes.
I can't give an example of the html because it's stripped in this forum

SELECT ID_COLUMN
, NM_COLUMN
FROM MASTER_TABLE
WHERE TYPE = 'EMPLOYEES';
I get the result:
EMPLOYEE_ID
EMPLOYEE_NAME
SALARY
The requirement is that I have to build now a RichTable use the attributes returned by this query (EMPLOYEE_ID, EMPLOYEE_NAME and SALARY).
I suppose that I have to create a ViewObject wich attributes and rows are populated at runtime (unknow columns at design time).
Anyone have any idea about how to do that??? Maybe a best practice or something like that...
I was reading this Oracle Tutorial http://docs.oracle.com/cd/E21043_01/web.1111/b31974/bcadvvo.htm#sm0341
but there is only two lines (39.1.8 Creating Dynamic Attributes to Store UI State) of how to create dynamic attributes.
Using JDeveloper 11.1.2 and Windows 7 x64.
Thanks in advance!

Struts and JSF Integration in OPDk-java based portlet

Hi,
thanks in advance for your help.
I'm developing a PDK java based portlet. For some reasons I cannot use the JSF bridge but I would like to integrate Struts and Jsf in my portlet, using Struts to manage actions and navigation and JSF (with ADF Faces components) for the view. I'm using the Strus-Faces library.
When I try to submit my portlet form, I receive the error "request URL not found on this server". I'm posting some exstracts of my code.
It's made of three pages: the main one "Integration1ShowPage", "error" and "result". The MainAction.java displays my mainPage, where there's a form. To keep it easy, when the user submits this form, the ActionName returns "success" and the "result" page should be displayed.
The MainAction works properly: the portlet is displayed but when I tried to submit the form I receive
The requested URL /provaDeploy/htdocs/integration1/integration1ShowPage.do was not found on this server.Could you please suggest me something?
Many many thanks,
B.
<struts-config>

Hi,
have a look at this whitepaper for how to use JavaScript in ADF.
http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
This link here (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html --> see sample 71) shows an integration sample between a Java Applet and ADF. Its a similar use case to yours

Extending VOs with attributes and creating new treetable columns

Hi,
I am relatively new to the ADF scene so please bear with if what I have in my mind is not even possible with ADF. I have searched hi and lo for a solution and now I thoughts it time to ask the community.
Anyways this is what I want to do. I have a simple DB Table that has a hierarchy i.e Trees with roots much like the Employee hierarchy. Except this table has ids for items that come from external systems ( via Web Services in my case ) and / or ids to items in a table that resides in the local schema. So basically this structure table of mine only has relationships and the detail items need to be joined via an association ( in ADF terminology ) in the treetable component somehow.
* Now creating the structure hierarchy is not a big issue. I have that part done already.
* I have the VO from WS ready that gets the items that I might need to show as detail columns in the tree table.
* Querying the local item Detail VO for detail rows might also be not that problematic.
* Merging the above 2 columns to create a consolidated row set is also not that challenging whereby each column header is premapped to internal and external fields. This mapping is configurable to add more fields as required by a user to the treetable.
What I am struggling with is that when I have this merged row set, how will I make it appear on the UI. The treetable seems to utterly not support this i.e. adding new columns at runtime. Following is what I have been able to establish till now.
* The addDynamicAttribute methods on the View Object are not meant for this purpose. While they do add the attributes and you can set and get them after using this method, they do not render and I can't find a way to dynmically rendering them somehow for tree table.
* Looked at the ADF dynamic components. They support only table and page. No go. Or do the whole tree thing somehow in the table component, Will look odd but might still work.
* Looked at this article ( http://one-size-doesnt-fit-all.blogspot.com/2007/05/back-to-programming-programmatic-adf.html ) . I found a comment in the forum regarding this that this might not be all that efficient. Not to mention the fact that it uses the deprecated TreeModels class in 11g.
** Just regarding this apporach what are the new 11g recommended TreeModel classes to be used instead of the deprecated one. I have read the follow-up post but that just points to the location of where the deprecated classes moved to in 11g under the apache contribution. And makes the example work under 11g. What was this TreeModel class replaced with. Anyone knows ?
** How could I access my VO objects in the TreeTableApater ? Can I declare my merged View object wrapped in a TreeItem POJO object. Theoretically it is on the view layer right ?
** If this approach is inefficient has anyone another solution that might work ?
Or just has anyone managed to extend the treetable in any different sort of way. Any tips/help pointers would be deeply appreciated.
Best Regards,

Hi,
So I had some time to look at this problem again. I created a ChildPropertyTreeModel and binded it to my treetable component and moved the generation of the columns to the jspx page. I got it mostly working but the columns generation part mostly escapes me still.
here is how the jspx page looks like that renders the treetable, and which works fine :
<af:treeTable rowBandingInterval="0" id="dynTTbl" var="row" expandAllEnabled="true"
binding="#{backingBeanScope.DynamicTreeTableBB.dynamicTreeTable}"
value="#{backingBeanScope.DynamicTreeTableModel}">
<f:facet name="nodeStamp">
<af:column sortable="false" headerText="Node Stamp" id="c1">
<af:outputText value="#{row.tableColumnVal[0]}" id="ot1"/>
</af:column>
</f:facet>
<af:forEach begin="1" end="2" varStatus="status">
<af:column>
<f:facet name="header">
<af:outputText value="#{status.index}"/>
</f:facet>
<af:inputText value="#{row.tableColumnVal[status.index]}"/>
</af:column>
</af:forEach>
</af:treeTable>
I want the forEach loop to look a bit differently like below :
<af:forEach items="row.tableColumnVal" var="columnVal" varStatus="status">
<af:column>
<f:facet name="header">
<af:outputText value="#{status.index}"/>
</f:facet>
<af:inputText value="#{columnVal}"/>
</af:column>
</af:forEach>
This should work for a list or array but evidently in my case it is not. I have a suspicion that the "items" attribute is unable to recognize the row.tableColumnVal attribute of mine. I have no way of checking this out or finding out if I am doing something wrong.
My sample project can be found here, if anyone quickly wants to run this on Jdev 11g
http://rapidshare.com/files/438880281/TreeTableTest.zip
P.S. I have tried to convert the tableColumnVal attribute to a List an array and a Map. The first forEach syntax works everytime but the second one fails always and I want the second one to work somehow.
