pls can u help in out.

Mak,
To show and hide your regions, you need to use conditions, please review the following section in the HTML DB documentation for information on how to do work with conditions:
http://download-west.oracle.com/docs/cd/B12037_01/appdev.101/b10992/mvl_a_con.htm#sthref1724
To validate your mail ID you could work with database constraints. However in order to customize your error message, I'd recommend using HTML DB validations, see the HTML DB documentation, chapter 7 for more information on how to work with validations:

Region Refresh

Dear All,
Use Case:
I have an input text and a region below it. In the input text, you could supply employee Id and the region should display Employee Information.
On click of a button, I am setting a pageflowscope variable.
<af:inputText label="Employee ID" id="it2"
                          value="#{pageFlowScope.employeebean.empId}"/>
<af:commandButton text="Search" id="cb1" partialSubmit="true">
    <af:setPropertyListener from="#{pageFlowScope.employeebean.empId}"
        to="#{pageFlowScope.empId}" type="action"/>
</af:commandButton>
<af:outputText value="#{pageFlowScope.employeebean.empId}" id="ot1"
    partialTriggers="cb1"/>
<af:region value="#{bindings.EmployeeInfoFlow1.regionModel}"
                     id="r1" partialTriggers="::cb1"/>I already setup my taskflow to read from this pageflowscope variable and already configured my partialtriggers.
<taskFlow id="EmployeeInfoFlow1"
            Refresh="ifNeeded">
<parameters>
     <parameter id="empId" value="#{pageFlowScope.empId}"/>
</parameters>
</taskFlow>My problem is that, the #{pageFlowScope.employeebean.empId} is not updated with inputtted value if the region
is present. But if I comment out the region, I see my input text getting updated values?
What could be the reason thanks?

Hi Jobinesh,
I notice that the region refreshes first after I clicked the button but before the pageflowscope input parameter was updated.
I already removed the partialtrigger on the region and I was hoping that it will accept the new value of employeedId that is in pageflowscope but I noticed
that it is still reading the previous value which is blank. The adf region is still returning data from the first call in the web service which is weird.
I simplify my coding and made simple code first without the region and managed bean and the used of setpropertylistener. I used this simplified codes.
I notice that this code is ok:
<af:inputText label="Employee ID" id="it2" value="#{pageFlowScope.empId}"/>
<af:commandButton text="Search" id="cb1" partialSubmit="true" />
<af:outputText value="Employee ID: #{pageFlowScope.empId}" id="ot1"
                           partialTriggers="cb1"/>But this one causes trouble, the taskflow call to the web service is still blank or null.
What's worst is that the output text value is unable to refresh its value
<af:inputText label="Employee ID" id="it2" value="#{pageFlowScope.empId}"/>
<af:commandButton text="Search" id="cb1" partialSubmit="true" />
<af:outputText value="Employee ID: #{pageFlowScope.empId}" id="ot1"
                           partialTriggers="cb1"/>
<af:region value="#{bindings.EmployeeInfoTaskFlow1.regionModel}"
                     id="r1" />I am finding this behavior really odd or I am just too dumb to understand I think.. ;(

ADF: big issues (bug?) with dinamic region refresh

Hi all,
we are creating a page that contains a component like the DinamicTabUiShell, but we have several problems refreshing the dinamic region we are using.
Here is a detailed explanation of our work.
We have page (monitoraggio.jspx) that has a panel stretch layout. Inside the top facet, we have navigation pane, that draws its tabs with a for each, looping through a managed bean (monitoraggioTabbedPane) collection . Inside the center facet, we have a dinamic region (monitoraggio.jspx, ID=r1).
We can say that we implemented the adf DinamicTabUiShell.
This is monitoraggio.jspx
   <af:panelStretchLayout id="psl2" topHeight="auto"
                                         endWidth="0px" bottomHeight="0px"

</pageDefinition>The content of the dinamic region is took from the managed bean of each tab added to the navigation pane: each tab keeps track (through OggettoCoinvolto attribute) of its content, and the dinamic region loads its task flow using the tab attribute OggettoCoinvolto.
Since we have to open tabs programmatically, to open a tab, what we do is:
- add a tab to the monitoraggioTabbedPane managed bean tabs collection (here we create the tab managed bean object, setting the OggettoCoinvolto property)
- try to refresh both the dinamic region and the tabbed pane.
All these operations, work flawlessly: we see that the model (monitoraggioTabbedPane tabs collection) contanis all the tabs, and each tab contains its correct task-flow-id, and this task-flow-id is correctly returned to the dinamic region.
The problems is about refreshing the view (both the dinamic region and the navigation pane)
To refresh them we tried using both AdfFacesContext.getCurrentInstance().addPartialTarget, and queueActionEventInRegion, we tried also setting the region refresh property to "ifneeded" and we changed a boolean flag passed as input of the region each time we wanted to refresh it, we used partianTriggers (you can all see in monitoraggio.jspx), but it does not work...
Sometimes we see that only the NavigationPane is refreshed, and sometimes when switching tabs, we see that the dinamic region does not change its content.
What can we do? Is our way to refresh region/dinamic pane wrong ?
We tried also to set the refresh property of the region to 'default' and using the refresh condition, changing it programmatically, but it does not seem to work...
Take, as an example, a refresh condition that simply gets the value of a boolean in a managed bean (monitoraggioTabbedPane.changed).
TO make the refresh condition work, is it sufficient to change the boolean with a simple assignment (changed = true), or do we need to use JSFUtils.setExpressionValue(#{monitoraggioTabbedPane.changed}, true) ?
Is there any way, in adf 11g, to dinamically launch an design-time-unknow-number of task-flows, where each task-flow is implemented as a region and each region must be associated to a different tab. Is possible to achieve this using dinamic region, or we are mis-using the dinamic region ? How can we refresh it ?
Many thanks to anyone willing to lean an hand...

I notice you have the activation property set to deferred.
<taskFlow id="dynamicRegion1"
taskFlowId="${monitoraggioTabbedPane.monitoraggioCurrentTab.taskFlowId}"
activation="deferred"
I would set it back to default or immediate for the sake of clarity. According to the doc, setting it to deferred has the same effect as immediate for JSP based pages. This is purely cosmetic.
You have refreshCondition set which is not what you want in this case.
xmlns="http://xmlns.oracle.com/adf/controller/binding"
RefreshCondition="#{monitoraggioTabbedPane.changed}">
You should clear this setting and change the refresh attribute to ifNeeded.
Your refreshFlag is hard-coded to true.
<parameter id="refreshFlag" value="#{true}"
xmlns="http://xmlns.oracle.com/adfm/uimodel"/>
When dynamicRegion1 is refreshed, it will only execute if one of it's task flow parameters has a different value then it did during the previous execution. refreshFlag should be set to an el expression that changes at least every time you change tabs if not more often depending on your requirement.
You mention "we changed a boolean flag passed as input of the region each time we wanted to refresh it" Did you set refreshFlag to an el expression in a different version of the code?
Sounds like you may have already tried all the above - if that's the case here some suggestions to help diagnose the issue further after you've returned to settings above.
1) Go to monitoraggio.jspx page def and - in the design tab - and right click to the right and the left of dynamicRegion1 and select Toggle Breakpoint to enable breakpoints before and after the task flow is evaluated.
2) Go to the design view of the task flows that you are showing in the tabs. Right-click on the each task flows default activity and select Toggle breakpoint to set a breakpoint.
When you run the application, you should hit the pageDef break points any time the task flow is queued for refresh. If you don't hit those breakpoints, then whatever you are doing to refresh the task flow isn't working.
Assuming you are successfully queuing your task flow for refresh, you'll hit the pageDef breakpoints. When you hit the first one (on the left), go the expression evaluator in the debugger and enter the el expression for refreshFlag and evaluate it. You want to verify that it changes as expected. If the value of the expression doesn't change before the next tab is displayed, the task flow won't be re-executed. If the values not changing as expected, you need to change the logic you use to update the refreshFlag.
You'll only hit the breakpoints on the default activities in your task flows when they are actually executed. If you hit the default activity breakpoint but are still seeing stale data, there's something wrong with the logic internal to the task flow.
Hope that helps.

OBIEE report with Click button ( want to perform some actions)

Hi Experts,
My users want to make adhoc changes to an OBIEE report where I want to place a click button at the bottom of the report. Once the changes are done, They want to click the button so that the most current logical sql is captured and then it takes to another http url .
If any one have worked or has any ideas on this, Please share. Thanks in Advance.
S

Hi S,
Can you elaborate on what you mean by capturing the most current logical SQL?
What you are asking is only going to be as difficult as it is to perform the above action. The button and the navigate are simple.
John Minkjan shows you how to make a clear button here.
Basically you leverage the OBIEE class XUIPromptEntry minibuttonOn.
Here's the code (NOTE: You have to change the curly brackets to angular brackets):
{div class="XUIPromptEntry minibuttonOn"}{a href="#" onclick="return PersonalizationEditor.removeDefaultSelection(false)"}Clear{a}{div}
You can take this and modify it slightly to fit your purpose:
{div class="XUIPromptEntry minibuttonOn"}{a href="(URL to move to)" onclick="(javascript function that performs your task)"}Do Action Button{a}{div}
In the above, you will put the URL you want to navigate to in the (URL to move to) area. Then in the onclick function, you're going to want to write a javascript function that captures the latest logical SQL and have OBIEE call that function.
All that being said, this effort hinges on whether or not a javascript function can perform your task.
If you can elaborate on what you mean, I might be able to get you started on that function.
Good luck and if you found this post useful, please award points!
Best regards,
-Joe

How can I go to other page when click button??

When I click button, the process of this button is be executed, then current page will go to other page.
1.I setup this button's Optional URL Redirect to other page, but process is not be executed.
2.I create a process and a branch(point: on-summit:after process...), not setup button's Optional URL. at this time, the process is be run, but not go to other page.
please help me if you know it! Thanks a lot!

Do you need the process to do something or do you just want to forward to the next page. In this case you just need the branch. In the configuration you can choose the button that forwards to the next page.
Configuration in the branche:
Target type: Page in Application
Page: The Page you want to redirect to.
On clicked Button: The Button you created on the page which redirects to the next page
Hope i could help.

How do I get all the control buttons in one place in 3.6.16, like they used to be in previous versions? Having the refresh and stop buttons between address and search windows, and the home button to the far right is awful.

In 3.6.16, the buttons are all over the place. In previous versions, the forward, back, refresh, stop and home buttons were all together. In this version, the refresh and stop buttons are between the address and search windows, and the home button to the far right.
I would love to have them all together as they used to be - much more user friendly that way. I have tried installing alternate themes, but the coding of this version over-rides the themes.

Firefox 4.0 has a combined Reload and Stop and Go button that appears at the right end of the location bar.
To restore the Firefox 3 appearance you can use these steps:
* Open the "View > Toolbars > Customize" window to move the Stop and Reload button out of the location bar.
* Move the Reload and Stop buttons to their previous position at the left side of the location bar.
* Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.
* Set the order to "Stop - Reload" or separate them otherwise to get two distinct buttons.

Can't open an Executable From Click Button

Hi, Everyone!
I've broken a learning module into several small project
files to match the client's standards. I've set up click buttons
within each file to open each of the published movies for the
module. Everything works as expected.
Now I need to create a standalone course using the same
files. I've published each file as a Standalone executable. I've
modified the open action on the click buttons to "Open URL or File"
and selected the appropriate .exe file as the target. I've
republished the files with the new click action. When I open an
executable and click a button to open another executable, I get an
error message stating that the page cannot be displayed.
What am I doing wrong? Can anyone help?
Thanks,
Bob Browne

Hi Bob
For starters, did you try simply exporting all related files
as .EXE files and test that way before making any changes? If so,
what were your results? I've seen before where once Captivate was
successfully linking to another movie, simply changing from .SWF to
.EXE format just worked.
Just a thought... Rick

Hello Experts,

Hi Sascha,
My code goes this way
data:
    lr_btn_ch   type ref to if_wd_view_element,
    lr_toolbar_btn_choice type ref to cl_wd_toolbar_btn_choice,
    lr_row_data           type ref to cl_wd_row_data,
    item                  type string,
    action                type string.
CALL METHOD view->get_element
EXPORTING
    id      = 'BTNCH'   " button choice Element in layout
receiving
    element = lr_btn_ch
lr_toolbar_btn_choice ?= lr_btn_ch.
DATA: lt_items      type string_table,
    lt_actions    type string_table.
loop at lt_dyntab into ls_dyntab.
append ls_dyntab-name to lt_items.
append 'ONBTNCH' to lt_actions.
endloop.
i get the data in the table lt_dyntab from API not in context
loop at Lt_items into item.
    read table Lt_actions index sy-tabix into action.
    create_choice_item( i_toolbar_btn_choice = lr_toolbar_btn_choice i_item = item i_action = action i_view = VIEW ).
endloop.
create_choice_item creates the menu item for the button choice..
My question is where should i call the map_on_action method. and how do i retrieve the index or reference in ONBTNCH method.
please elaborate.

The wheel click button does not open a new window since the latest update (9.0.1)

Hi
I just want to report this bug in hope it will be fixed asap
The wheel click button does not open a new window since the latest update (9.0.1)
Thank you

Middle-click or click the scroll-wheel on a hyperlink has always opened a '''new Tab'''. Any chance you had an add-on that changed that action, and now that add-on is disabled or incompatible?

Zooming a Finder Window (Clicking Button)

I am trying to zoom a window in the Finder but I can't make this script work. Basically I have a folder that I open up and I want to resize the window to fit the contents (just like hitting the Green button on a window in the Finder).
I get an error saying: "System Events got an error: NSReceiverEvaluationScriptError: 4".
Here is my script so far:
+tell application "System Events"+
+tell process "Finder"+
+tell window 1+
+click button 2+
+end tell+
+end tell+
+end tell+
Can anyone see just what I am missing?
Am I going about this the wrong way? Been spending hours Googling for an answer to something that seems so simple.

Windows are numbered in the order that they are layered, with number 1 being the frontmost, 2 being the next one back, etc. When you click on an item in column view, you get a new column, not a new window. I am guessing that you have the Finder preference set to open folders in a new window, in which case double-clicking on a folder will open it in a new window. In that case the new (front) window will be number 1, and the previous front window will be number 2, although both will have the same name, which may be where the confusion is coming from. The name of a Finder window (whatever the number) is the currently selected folder, or in the case of files or multiple selections, the containing folder, so there can be several windows with the same name if they are targeted at the same folder.

Click button not working

Have a white MacBook with separate click button and the click button is non-responsive. Yes, I've bought a new keyboard/top assembly and replaced it but the click button is STILL unresponsive. Tapping works fine and using a mouse works normally as well but the click button isn't functioning at all. Is there another hardware component I can fix or replace other than the keyboard/top assembly?

Hello Michael,
If your Macbook has a removable battery take it out and run it from the mains power.
If it works OK it probably means that your battery has become swollen and is pushing up on the bottom of the track pad and stopping it working correctly.
You will need a new battery. Go to a genius bar and you may get it replaced for free depending on the number of cycles it has done. 300 cycles seems to be the magic number. Over that and you will probably have to pay. Under that and you may be lucky.
Hope this helps,
Alan

Left click button not working on mouse

Using an HP Pavillion g series notebook with windows 7 and all of a sudden my HP wireless mouse left click button doesn't work. checked to see if it was clean, changed the battery too. Right click buttonis working as left click now. Driver software is upto date. Only 2 years old with light use. What's up?

I also get what looks like tiny barcodes to the top right of my mouse pointer.
That is usually a software corruption problem.
Disk Utility ( Repair Disk ) is a good place to start.
