Component for the statement of the problem on a Page

Dear all,

I can do not to understand how to find components in ADF Faces application.

public String getButtonText() {
     FacesContext fctx = FacesContext.getCurrentInstance();
     UIViewRoot root = fctx.getViewRoot();
     RichCommandButton button =
          (RichCommandButton)root.findComponent("r1:0:pt1:pt_cb1");

     if(button!=null){
       return "Found";
     }else{
       return "None";
     }
}

Take my code above.

I used firebug to check if this component is present, but it always returns null.

Please watch my Firebug link for image http://imageshack.us/f/840/61382955.jpg/

Can someone tell me why it is return null? I thought it back this component.

Thank you.

Hello

I suggest an iterative approach

1. from roots, find r1 (region)
2 from there, find pt1 (model region)
3. from there find "pt_cb1" (you are sure that the ID is = pt_cb1

Hello

I found the solution for the problem of sound-acpi with Toshiba P100 (it works with P100-219 at least). I can provide the source modified and compiled table DSDT, but I would like to know if it is possible to get these changes in the next update of the BIOS?

See you soon,.

Hi Mik

As you know that it is not possible to find info on the next BIOS, especially if you want to have some information about the Linux operating system. Just wait and see if some forum users pointed out something on the subject.

Greeting debuisson,

Welcome to the Support Forums!

Are you using the browser (Google) stock on a very regular or frequent basis? If Yes, brief gel is a known problem due to a memory leak in the stock browser that Google has not yet difficult (there are under all versions of Android OS to date). Basically, the continuous browser to consume your memory over time, based on the sites you visit and the length of time, it is active, which makes the system pause/freeze periodically. There are two ways to deal with this, either install a third-party browser (such as FireFox, Dolphin, Opera, Chrome, etc.) or if you really prefer the stock browser, restart your Xoom every two days (to clear/free memory and cache).

Apart from the browser, a third party application of thugs can cause this as well (especially if there are conflicts). The rule of this point, try to use a surveillance (as SystemPanel) application to monitor what is active in memory when you encounter the gel. Close active applications one by one until your gel goes and then locate the updated versions.

Please let me know what you find.

Method of onPageLoad for the problem of the UI component

Hello
I am facing problem in access to the (button) user interface component on the page in the onPage() method. I use the ADF with JDveloper 11.1.2.3 technology
the use case is:
I'm trying to disable or enable a button in the page loading based on information from the database form. in my situation am running a query check if there is a file stored in the database; If there is a file, a download button should be enabled allowing the user to download this other wise that the download button should be disabled. I tried the following code in the onPageLoad() method:
```
public void onPageLoad() {

        // loading Previous file so the user have the option to download
      
        // if there is privous file stored in db


        if ((BlobDomain)tempVO.first().getAttribute("File1") != null) {


            System.out.println("there is a file stored in db from OnpageLoad method");


             this.downloadButton.setDisabled(false);
         
        }


        else {
            // if there is no file stored the download option should be disapled


            System.out.println("no file stored in db form onPage load");


                this.downloadButton.setDisabled(true);


        }
```
and I got this error after running the previous code:

Hi Vikram,

Thanks for posting the question in the Microsoft Community!

You get the blue screen error in the computer.

To work with the issue, I suggest you to visit:

Resolve stop (blue screen) error in Windows 7

Note: When you restore the system to a previous state, programs and updates installed later will be deleted.

Note: When checking a disk for errors, if bad sectors si des secteurs defectueux sont are found then the system tries to repair sector. All data may be lost. So make a backup of the data.

Note: When you format a disk, all data will be lost.

It would be useful for us to identify the problem, if you could upload the dump file.

Fix for the problems of release of WebHelp with IE 11 breaks search

I use RoboHelp HTML 9 and you had problems with WebHelp generated in IE 11. The table of contents was completely empty and the 'Search' tab was going well, but have not worked. Everything worked fine in Firefox. After much research online and experimenting in these forums and elsewhere, I was able to get the table of contents to display properly in IE 11 (and Firefox), but the fix caused the Search tab to stop functioning in accordance with this other forum post RH9 Webhelp search function does not work properly.
I need to have BOTH COT and research displays and works correctly but in order to get the table of contents displays correctly I had to change the preferred Format "Pure HTML" and, according to the above-mentioned position setting, it's what messes up the search function. is there a solution that will enable the TOC and research work properly?
Here is a summary of the steps I took to get to this point:
- Tested WebHelp output of two different projects myself so that the startup project Salesbuilder - all would display or function properly in Firefox but not in IE (empty TOC and non-functional research) 11.
- Find a "patch" for RH10 exactly the problem I have experienced with RH9 but wasn't able to find a version for RH9. Since the patch included only 2 files (whutils.js and whver.js), I saved these files in the RoboHTML\WebHelp5Ext\template_stock directory and replace them with the new.
- Regenerated one of my RoboHelp projects - still does not work in IE 11 and now does not work in Firefox either!
- Tried to turn on mark of the Web but this did not help and did not allow for opening PDF that is necessary for one of the projects, I turned it again.
- Change the preferred Format setting "Pure html" instead of "DHTML" and the table of contents displays and worked properly in 11 IE and Firefox! Hooray!
- Celebrated for 10 seconds until I clicked on the "Search" tab and see the input box filled with letters of the alphabet with other random letters, words, numbers below. It looks almost like an index, but none of my projects using an index and I've not generated one or the other project.
- Found the post mentioned above which States that the solution is to change the preferred Format of DHTML, but when I do this I am back empty TOC and look clean but non-functional search!
- I have now deleted the search the output of one of the projects tab, it is not really necessary, but I need to find a solution for this for my other project.
Two of my projects are run locally - it is documentation that is distributed on a CD release and the other is CSH, which is loaded on the local server with the software for which it was created.
Dorothy
Note to administrators: Sorry, but I posted this in response to a previous post , summary, Index, & Research do not appear in the generated... help -then perhaps it should be removed from this thread to avoid confusion.

There is an official fix for RoboHelp 9 IE10. But who is unable to solve your problem. If you PM me, I can send you a pre-test to fix IE11 on RH9 to see if it works in your situation.

The only real solution is probably to update RH11.

Kind regards

Data for the problem of dynamic regions was interrupted
Hello. I use JDev 11.2.2 and stack complete ADF.

This is when I try to load a new stream of work of a dynamic region. Let me give a step by step test case:

1 - using HR, model of generation: create objects (entities, objects View) for the employees and departments tables and an Application Module.

2. - in VC, add a page facelets with layout of two columns, first for a tree for the switching of regions and a dynamic region in the second column.

3 - create a page fragment that includes a generated table view in data controls and another fragment of page view of departments.

4 - create two workflow bounded, for fragment employees and another for the fragment of departments.

5 - drag and drop workflow bounded to create a dynamic region in the second column of the home page. Of course by selecting backingBean for new bean (default value is increased demand).

6 - in the model, create a static filled List View object with two attributes: a workflow id and a description

7 - in VC, generate a tree in the first column of the home page

8. - write a component of the tree selection listener to read the id of the current workflow and set this ID value of workflow dynamic region at the appropriate bean.

9 - set triggers of partials in a dynamic region in the homepage to listen for events from the tree.

10 - run and try to load a new workflow clicking in the tree. An alert is triggered with this message:

* "The content of this page could not load as expected because data transmission has been interrupted. Please try again or contact your system administrator. » *

And the newspaper is displayed as a result of lines:

* < FaceletViewHandlingStrategy > < handleRenderException > error rendered View [index.jsf] *.

If the taskflow taskflow id that has not worked is established in bean area Dynamics initial taskflow for the region, it works, but the other taskflow fails...

Any suggestions?

CPOI
Hello

+ "Make sure selection backingBean to new bean (default value is increased demand)". "+"

That's your problem. Set the viewScope bean to avoid dynamic region to switch back to the default workflow after each request

Partial cure for the problem of model Icon Editor

I'm driven crazy by models Icon Editor behavior (which I love and use all the time). What happens is I'll open a project, start to make icons with my set of templates (all saved in LabVIEW Data\Icon Templates\VI\BS icons) and especially if I've included copies of screws that have been developed, say, two years ago and copied from another file on the disk, will notice two copies of the model , with the second copy often in... part \VI\3rd. Now, these are clearly my models, just saved in the "wrong" place.

Get rid of these models in doubles was very difficult - I just spent half an hour doing it. You delete all the files in the 3rd part, open the icon editor and see only one copy, then start doing things and Bingo!, the model appears in the model list in the Icon Editor, but also the file reappears in the 3rd party folder. What should do?

So I did a search on the Web, found a fool named "Bob Schor", which has asked about it in 2011 (on this Forum, of all places!), got a few suggestions, but does not solve the problem. So I tried something else.

I noticed that there is a lot of. BIN files stored in the model icon folders, with file names that appear to reference different versions of LabVIEW (e.g. Templates.15.0f2.bin). On a lark, I deleted this file, deleted the folder of 3rd party model, LabVIEW has reopened, reopened the icon editor, and (he said, I hope) the problem seems to be solved. There is no more 3rd-party file appearing in the model list, icons are not really, it can't be, maybe if I killed the evil Dragon. I'll let it rest for a week and if it still seems to work, will return and mark this as a 'Solution '. Comments and other ideas welcome.

Bob Schor

Is there a step I missed, but just found. In the icon editor itself, there is a setting to know where (by default) record the models he finds inside a VI already, but are not in the calibre of icon file. This setting is under Tools, icon editor properties. In the 'Model' category, you should disable "Save third icon templates" which, like a default value of \Icon Templates\3rd, part.

I am currently testing (on several machines, all configured slightly differently), these ideas and so far it seems to work. I had a small panic today when the '3rd party folder' with additional copies of some of my models began to appear that I opened the existing screws, but turning the switch "Record the icon of third-party models" seemed to solve this problem. I'm almost ready to mark this (and earlier versions) post as a Solution...

I found the FIX for the problem of HP4500 ink cartridge!

I had problems with my ink cartridge three colors... just like many others. After searching endlessly with no solution to the problem, I decided to take a flashlight and look inside the printer. What I found was a piece that had become crooked behind my color cartridge. It was a simple solution... I took a long thin to flat head screwdriver and pushed very GENTLY in place. I then ran a TEST PAGE and ALIGNMENT before I printed anything... it worked! Here is a picture I took before I did the setting of the insert on the left hand side, it's here that the color cartridge is going... If you notice, it appears to be crooked... he slipped easily right now in place. I've reintroduced the cartridges and closed the door. IMPORTANT * make sure that you unplug your printer before attempting to solve this problem * good luck and hope it's a permanent and not temporary solution

Hi coolinutah,

Thanks for the valuable information and goot to know that you were able to correct and solve the problem.

Studio EN - is there a work around for the problem of referencing data from a grid with a different connection of DB and # different dimensions?

Hello
I'm making reference to a column in a different grid with a different database connection. I did some searching in the forums, and it seems that it is a known problem with EN Studio. The problem is that if 2 different database connections have different number of dimensions, then the reference will throw an error.
For example, what I try to do, is below:
In grid2.column [A], I have the following formula:
Grid1. Column [A]
The result is an error.
The ultimate goal is to have a base of variance formula in the grid between grid1 and grid2, who have connections to different database with a different number of dimensions. Is there a solution to this bug? The example of the basic formula is less to:
Grid1. Column [A] - grid2.column [A]
Any help is very appreciated!
Thank you
Tiffany

Have you tried to change the database connection in a row instead of create a new grid?
