Settting render attribute doesn't render the child taskflow

i am having 2 taskflows which is consumed by a consuming page.
On the consuming page on which these 2 taskflows are dropped as region.
the 2 regions are placed along with some buttons inside separate panelGroupLayouts.
i mean in 1 panelGroupLayout 1 region and button is there and similarly in 2nd panaleGroupLayout other regin and button.
On consuming page there is next button , i have set it to render 1st panelGroupLayout.
when i click Next button it renders the 1st region and buttons correctly. But when i click the back button from the 1st region and come back to consuming page and again click NEXT button, it remains at the same consuming page
and doesn't render the region 1 and its buttons again.
in code, on the 1st panelGroupLayout i have put rendered="a variable in backingbean of consuming page which i am setting to true on the next button click event".
Please help in this issue.
Thanks in advance.

user, please tell us your jdev version!
it you yet the rendered property to false you have to do a full refresh to get the region back. Use the visible property instead.

Stopping the automator app doesn't end the child process

Fairly new to Automator and I created an app to start a process for hosting a small server for VoIP. However, when I stop the app, the child process that was created continues to run and I have to end the child process in the activity monitor using the stop command. Is there any way to fix this?
The workflow used in the app is as follows
cd /Applications/teamspeak3-server_mac
./ts3server_mac

Perhaps you should check the Console logs to find out what's going on. One thing that I would examine is that if you run the app in the Dock, then it cannot quit the Dock hence the app fails to properly run. Just a thought.

Forcing end user to open the child form in the resource request dataset

Hi,
Is there any way where we can force end user to open the child form of a resource request dataset and enter the values for the attributes in the child form. The child form attribute is mandatory. However, currently, OIM allows user to submit the request without opening the child form and to enter values for child form attributes(which is mandatory).
Thanks.

Child dataset attributes are set to required="true". But it will come into picture only if end user opens the child form. If he forgets to open the child form, still he is able to submit request without entering values to the attibutes(whose required=true) in the child form. OIM is alowing to submit request if he doesn't open the child form.
I hope i was able to put it in corrrect way.
Thanks.

UI Dynamic Tabs Shell - Child Taskflow not rendering / instantiated

Hi All,
I have had this problem, ever since rebuilding my application using Jdev 11.1.2, although I am not convinced this is a problem with Jdveloper verison.
Basically, I have developed the UI to open new task flows as dynamic tabs, making use of the tab context API as published. The application works perfectly and I can create new dynamic tabs and close them fine.
Once I add a data control af:table to the child taskflow however and display this, the taskflow opens fine. The weird behavior begins, after I close this, using the standard UI removecurrent tab icon (the little x to the far right of the form), I cannot re-open another task flow. A new tab is created, however the taskflow within this (one being called) does not render or instantiate.
If I remove the table from the page fragment, normal behavior resumes.
I am at a complete loss as to why this is occurring.
Any insights would be great.
I would also like to point out... no errors are written to the log, even at the Finest level. The launch method also completes successfully. If I don't close, I am only able to open a maximum of 3 tabs before the render issue occurs.
Cheers,
Simo

Hi Frank,
Well you were right, this was an implementation issue, but one being caused by some different behaviour in 11.1.2. I was actually setting the tab_id dynamically after the user has selected a row, via clicking a link. The ID was returning null hence the weird tab behaviour.
Ironically, it was actually another recent note that you have posted http://blogs.oracle.com/jdevotnharvest/entry/jdeveloper_11_1_2_command that led me to the solution!!
So thanks inadvertently !!
Cheers,
Simo

Ok Frank,
That is what I did. I would to report a bug, This is not working when the train is in dialog mode, then it crashes when I try to leave the child taskflow. In not dialog mode it works perfectly.
Is it possible to get the train button bar working in the child train taskflow
thanks Edwin

Parent TaskFlow doesnt get control back if child taskflow is closed in IE

Hi,
We have a bounded taskflow , which internally calls a child taskflow in a new window. The problem is if we close the child taskflow window before it renders completely it doesn't pass the control back to the parent taskflow. After that parent window is unusable and we have to close it start it again.
This issue is only seen in I.E (i am using 7.0) and chrome , it works fine in Firefox mozilla 3+
Any idea what can be the issue here???

Hi,
I suggest to you create a test case and file a Service Request with customer support

Executing Child Taskflow Method from parent taskflow page

Hi All,
I have one issue with checking dirty data form Parent Taskflow button to check dirty data update in Child Taskflow page's view Object.
JDev version: 11.1.1.3
Scenario :
Outer Container page has back button which need to check wherethere child taskflow has dirty data update or not. Child Taskflow transaction is always create new transaction and non-shared. But from ControllerContext, the root am service still associated with other viewobjects i.e. is loaded in others tabs in that outer container page, which is also checking dirty data from another tabs' viewobject dirty data checking (I need to avoid this issue that's why not working for me with controller context). I am thining to execute the child taskflow method from parent page on back button to check dirty data update for that tabs' page only. For it, how can we get access child taskflow method from parent page with static region taskflow. Is there any solution to implement like this? thank you so much.
- Robin

Hi,
this should work:
1. child task flow has input parameter "parentBean" defined.
2. The child task flow has a managed bean "ChildBean" defined in pageFlowScope with a property "parentBean" with setter/getter.
3. the parentBean input parameter references (in its value roperty) #{pageFlowScope.childBean.parentBean}
4. The parent bean is configured on the parent view task flow (viewScope) and passed as a task flow binding input parameter. The parent bean has a boolean property "childFlowTransactionDirty"
This allows the child bean to invoke the parent bean childFlowTransactionDirty to tell it that the transaction is dirty. On the parent view, you would just check the parentBean state for this property.
Next is how you set the value on the parentBean from the childTaskFlow. One option is to use a RegionController on the PageDef file of ADF bound views in the child task flow.
public class MyRegionController implements RegionController {
    public MyRegionController(){
    public boolean refreshRegion(RegionContext regionContext) {
     int refreshFlag = regionContext.getRefreshFlag();
      //get access to the ChildBean and its parentBean property. Then call
      //ControllerContext .... to check the transaction state
      //update the childFlowTransactionDirty property
      ((DCBindingContainer)regionContext.getRegionBinding()).refresh(refreshFlag);
      return true;
    @Override
    public boolean validateRegion(RegionContext regionContext) {
        regionContext.getRegionBinding().validate();
        return false;
    public boolean isRegionViewable(RegionContext regionContext) {
        return regionContext.getRegionBinding().isViewable();
    @Override
    public String getName() {
        return this.getClass().toString();
}Next: When users press the back button in the parent view, you call the ParentView bean childFlowTransactionDirty to check the child task flow transaction to be dirty or not

Why does Premiere render the same sequence sometimes fast and sometimes really slow?

I use Premiere Pro CC 2014.
I have a Nvidia GTX 590
Intel Core i7 X990 @ 3.47GHz
24GB RAM
Windows 7 (64)
200GB free space on an SSD drive and 2 more drives with each 1TB free.
I'm having trouble with performance when rendering sequences.
The sequences themselves are pretty simple. They contain MOV files from my Canon EOS 5D Mark III and transparent PNG files as overlays for titles and additional graphics.
I also use lumetri looks and have turned on Cuda rendering. As a codec for exporting I use H264 (fullhd, 25fps, 20mbits, 2pass, max render quality, max depth)
Whether or not I export in Premiere or via AME doesn't matter, the problem stays the same.
Now, when I start exporting, at one point, which is seemingly random (sometimes at 35%, sometimes at 60%, sometimes at 2% - I'm talking about the same sequence!) rendering becomes really really slow (~1 hour for a 3min video), and I don't understand why. I keeps slow until the whole sequence is finished. But before that, rendering was fast!
But sometimes, I'm lucky, and - after restarting my computer and Premiere, the same sequences render in whole, in under 2 minutes!
So obviously my computer is able to render fast. But it does not always do that. Sometimes - even after a fresh reboot, I'm out of luck and the same sequence renders in an hour - but only after a random point in the sequence.
It's as if Premiere stumbles and can't get up again. The only thing that CAN help (though does not alway), is rebooting the system and hoping for the best.
Where does this strange behaviour come from? I use ordinary footage, ordinary filters and an ordinary export codec. I have lots of RAM and lots of disk space
I have not found a topic in this forum with a similar problem

Similar problem here but on a Mac. AME is always much slower than directly exporting from Premiere, but if I start to get slow renders a reboot always sorts the issue out.

SP online 365 - Unable to render the data. If the problem persists, contact your web server administrator.

Help needed urgently, i'm pulling my hair out on this one!
Using SharePoint online (365) I am trying to create an external list to a SQL table. I go through the steps in SP designer and finally create the external list but when I go to the list I get the error:
Unable to render the data. If the problem persists, contact your web server administrator.
I have read all of the posts on here to fix this and they are mainly for on premise; the powershell doesn't work with spOnline and I have added permissions into the BCS service application but nothing works. I read that it is not possible to connect
sharepoint online to an on-premise SQL database so I moved the SQL database to an azure SQL service server but I still get the same error.
I have a "test" on premise sharepoint which I have tried this on and it works fine so it must be an issue with SPonline! does anyone know how to get BCS connections to external data working in sharepoint online as external lists?

Hi,
In SharePoint online, we support:
Business Data Connectivity (BDC)
Data Source types, including Windows Communication Foundation (WCF)
SQL Server Azure connectors
I'd suggest you refer to the article below:
https://support.office.com/en-us/article/Make-an-External-List-from-a-SQL-Azure-table-with-Business-Connectivity-Services-and-Secure-Store-466f3809-fde7-41f2-87f7-77d9fdadfc95?ui=en-US&rs=en-US&ad=US
It describes about how to use SharePoint technologies to access data from a SQL Azure database without having to write code, including create an External List by using Business Connectivity Services (BCS) and Secure Store. BCS connects SharePoint solutions
to external data, and Secure Store enables user authentication for the data. By using an External List, you can display the contents of a table from SQL Azure in SharePoint Online. Users can read, edit, and update the data, all in SharePoint Online.

Can the Add To Cart image render the hand cursor to look more like a clickable link?

I have used a custom image for the add to cart tag - {tag_addtocart,<img src="/images/fg_buttonbuy.jpg" width="203" height="76" />} - however our client is worried people will be unsure if that's where they click to add the product to the cart as the cursor stays as the arrow and doesn't change to the hand like when clicking on other links.
I was pointed to this page http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_button_test and told I was able to customise my code so that it did render the hand. I've done a little bit of trial and error however am unsure how to add the button code to the add to cart tag.
If anyone is able to assist it would be greatly appreciated!

I tried the target the class but there was no class associated with the button rendered:
<img src="/images/button.gif" alt="" onclick="AddToCart(83934,3349995,'',3,'','',false);return false;">
Can I wrap it in <span class="button"><img . . .></span>? If so does it need to be assigned to the link. ie. .button img a { cursor:pointer; }
Thanks.

Help render the raw files edited with camera raw how?

Hi
i have a problem
i use bridge cs5 (updated) to browse my raw files
often i open my raw files with camera raw inside bridge cs5 and make some corrections like exposure , saturation , contrast and so on
but after bridge doesn't re-render the files
i mean the thumbs ,previews , the slideshow still are in default setting
when i click and open with camera raw inside bridge or with photoshop cs5 ,the raw files look with corretions
but again bridge show me not with the corrections
i run under w7 32bit
what could be the problem?
thanks

mantralightroom wrote:
i see previews and thumbs with the edits but with a big delay
thanks
If you are using HQ On Demand you will get fast thumbnails, but there will be a delay in generating the preview as Bridge builds it.
The Always HQ takes more space, but faster as the data is already in cache.
Hope this helps.

Render the findform

I want to render the findform so for each attribute he will choose a new line and he will show the attribute on each differnt line.
Can't comboboxes, checkboxes, radio groups be supported in the findform?
How do I have to change the code for the render-function so I can customize the view of the findform?
I would like to loop the output by looping the different attributes and displaying each content
for (int i=0; i<attrs.length; i++) {
aTable.addHeader("  ");
aTable.addHeader("   ");
aTable.addHeader(resHtml.getString(resData.COLUMN_NAME_PROMPT));
aTable.addHeader("      ");
aTable.addHeader(resHtml.getString(resData.COLUMN_CONDITION_PROMPT));
aTable.addHeader(resHtml.getString(resData.COLUMN_VALUE_PROMPT));
aTable.addHeader("      ");
// }

The FindForm is just one example of how to build a search UI. You can take the existing source code and copy it to create your own application-specific search form. The answer to your question is yes, because HTML FORM elements can contain various input types such as text,textarea, radio, checkbox,...
I would recommend that you build your customfindform using a JSP page and DataTags so that you can customize the user interface via your favorite html editor. You can also take the existing class as a starting point for your FindForm DataWebBean.<HR></BLOCKQUOTE>
