Sounds more like a JSF thing in stead of an Oracle specific thing. JSF components have a rendered attribute with which you can include/exclude them based on some request time expression.

Then in the JSF page you can query the session bean for its credentials using an EL expression, something like:
<h:selectBooleanCheckbox value="#{yourBackingBean.checkValue}" rendered="#{user.admin}"/>the "if a checkbox is checked" part is a little vague; the checkbox is already checked when the page is loaded, or part of the form needs to be shown/hidden when as soon as the checkbox is checked?

How to hide fields in UIX form
Hi
I need to update the table with last_updated_by and last_updated_date every time if any change to the record. But I do not want to show these 2 fields on the screen.
Could you help me how to hide fields in UIX form/any procedure to insert the data to database with out placing them in the screen .
Thanks in advance.
NRKNow that you mention it ... the rendered flag will stop the field from being rendered. So it's not even in the page. Stupid me.
Have a look at formValue. These are rendered, but invisible fields in a form. That should do it (hopefully).
In prepareForDML() you could simply call the setter of your date attribute that stores the date of the last update. There you pass the current date, or you could fetch the sysdate from the database and pass that. If you go that way, then the EntityImpl could make these adjustments automatically when inserting or updating and you wouldn't even need these fields/bindings in your UIX page.
Just check what the operation is, and if it's an update or insert then call the setters of the attributes you want to update. Then call super.prepareForDML(). Something like that.
It all would happen in the middle-tier, client not involved.
So formValue should work, and the prepareForDML() stuff should also work. Don't know which way you want to go.

How to hide part of search results to particular users?
Hi,
Is it possible to hide part of search results to particular users? If it possible can you please tell how to implement?
Thanks, ChinnuHi,
According to your post, my understanding is that you wanted to hide part of search results to particular users.
You can use the security trimming to achieve it.
By default, Enterprise Search results are trimmed at query time, based on the identity of the user who submitted the query.
When results are returned for a user's search, the Query engine performs an access check for the user's identity against the security descriptor stored in the content index for each item in the search results. The Query engine then removes any items in the
search results that the user does not have access to, so that the user never sees these results.
SharePoint uses the access control list (ACL) associated with each document to trim out query results that users have no permission to view,
but the default trimming provided by SharePoint (out-of-box trimming) may not always be adequate to meet data security needs.
In that case, you can custom the security trimming to meet your requirement.
There are some articles for your reference.

How to Hide buttons in HCM forms
Hi Experts,
In "Transfer" forms, with out filling mandatory fields if I press button "Check and Send" then I get a extra button called "Continue". When I click on "Continue" it takes me to the next page without asking me to fill mandatory fields. Here I want to hide that "Continue" button.
Like wise in "End of Probation & Short Term Contract" forms, with out filling the mandatory fields if I press button "Check and Send" then I get a extra button called "Forward to Expert". In my case I want to hide "Forward to Expert" button also.
Please help me to fix these issues.
Thanks & Regards,
Harish Kumar N

When closing old threads, there is no need to add a comment. Adding a pasted answer like "fixed by myself" only brings old threads to the top of the forum list and pushes current ones down. If you do add a comment, please indicate just how the problem was resolved.
Edited by: Rob Burbank on Nov 2, 2011 9:30 AMYou do not need to add this field to your list. In the view V_T588MFPROPS (SAP delivered), this field is set as mandatory. In configuration, you must maintain the view V_T588MFPROPC (Customer area) and make sure the field is not set to mandatory. This will override the SAP delivered setting and the error message will be not be displayed.

Hello everyone
How to use URL like like
http://domainname/path/something?action=xxx&target=yyyIt depends.
Firefox should show you the true link, i.e., sites should not be allowed to fake the mouseover, but for long links, the display might be truncated.
Regardless of the link's href=url, many links have a click handler that navigates to an altered, intermediate, or different URL. Sometimes this is coded right into the link (onclick="blahblah") while it other cases, it is quite arduous to discover.
Yet other links may be the result of a submitting form. This allows the site to use hidden form fields for some of the parameters.
If you select loosely around the link, right-click, and View Selection Source, can you see how the page is constructing the final links? -

[email protected]go in your <forms-home>forms\server - directory. there is formsweb.cfg.
All the [default] - parameters are global. If you don't set a parameter in your own section, then the fallback-parameters are stored there.
at the end of the file you should write your own settings:
e.g.
# myConfig - this is an example for your own Config-Section
[myconfig]
form=myStartForm
imageBase=codeBase
splashScreen=no
separateframe=true
try it

How can hide the word oracleas forms service in applet
my dears :
if I want to appear the name of our company in applete instead of this word oracleas forms service
how
thanks in advanceHi,
Copy your image (either .gif or .jpg) in %devsuite_home%/forms/java for example for me it's : C:\oracle\DevSuiteHome_1\forms\java
Then in your formsweb.cfg point to your image begining with /forms :
# Forms applet parameter
background=/forms/java/logocca.gif
Restart your oc4j
Launch your application.
NB : The names are case sensitive, i.e /forms/java/logocca.GIF will not work
It's important to mention /forms/java/ because your c:/ is not seen by the web server

How to hide save changes alert window when no changes made to the form
hi,
in my form when i close the form without making any changes it displays do you want to save the changes alert.how to hide this alert when no changes are made to the form window.
regards
YesukannanBe advised that this solution will also exit the form without saving the changes and asking anything if the user did make changes.
You're probably changing some field from a PL/SQL trigger (hint: post-query or when-new-record-instance are likely). If you set the value of a field from a trigger or program unit that also marks the record as changed for Forms. Forms will then ask to save the changes when exiting the form.
If you want to prevent this, reset the record status after you change the field in the PL/SQL code.
Maybe you are looking for
