OFA find page error "search cannot be executed.
Hi friends,I'm new to the framework of OSTEOARTHRITIS. I just created a new search page (which is my first page of OFA :-)). I got an error "Unable to execute the search because the table has changes pending that would be lost.", I am able to solve the problem, but it's just luck. I played a bit with some values, this is how I fixed it. But I want to know how we get the error and what we must do to fix it. I want to know the concept and want to remedy this by chance.
Here is the code and what I've done (I got all the Online code).
Step 1: Created a simple search with 6 columns to the display page. All fields has 'Read Only' "mark as 'false'.
Step 2: Run the page, and once I gave values in the search field I am able to see the results.
Step 3: Then I thought about playing around on the page and tried the following scenario
At the start of the page must all data and research on the basis of the values it should only show the corresponding data.
Step 4: To achieve step 3, I created a method in AM as follows and calls the page controller.
public void initPurchaseorderVO()
{
//get a handle to the View Object that we wish to initialize
OAViewObject vo = (OAViewObject)getPoSearchVO1();
if (!vo.isPreparedForExecution())
{
vo.executeQuery();
}
//Create a blank Row
Row row = vo.createRow();
row.setNewRowState(Row.STATUS_INITIALIZED);
}
Step 5: Regenerate and run the program, now I am able to view all the records, but when I tried to do a search by completing certain values in the search field I got the following error message
The search cannot be executed because the table has pending changes that would be lost.
Step 6: After some searching online and play with some values, I changed the following line in AM as follows
Change row.setNewRowState(Row.STATUS_INITIALIZED)
To row.setNewRowState(Row.STATUS_NEW)
or comment row.setNewRowState(Row.STATUS_INITIALIZED)
Step 7: Now, I am able to run the page, display all the data and then when I tried to use search option data appear as it supposed to be.I want to know why "row.setNewRowState (Row.STATUS_INITIALIZED)" is the source of the problems and what it mean? and there at - it another option to resolve the error I get?
Thank you in advance
Sri.
Sri,
Line = vo.createRow () returns an object of class useful (inherited from oracle.jbo.Row import) line when you
Create a new page of the OFA record.
The main objective of the creation of a line of view object is to receive values from the page once the user causes a form submission (for example, by selecting the application button).
This brings the new registration information at the intermediate level.
We can create a new record in data coming from the screen of the OAF without creating a "view subject line' (IE one line other = vo.createRow ())
This will create only a blank midweek tire line, after that create this line vo user can insert using vo.insertRow (row);. Once the empty row is created and inserted then only registered values OFA is captured and committed in the database using getTransaction () .commit ();
Summary : to create a new record, you must create a blank line, so you must use the line line = vo.createRow)
As you perform the search operation you will get step detail in the Oracle document in that you don't have to search online.
Its available in doc - Index.html jdev go looking for exercise, it is easy and explained in step-by-step detail.
Let me know if you do not find this exercise, will help you to understand where it is exactly.

Get error in the search for the page cannot be executed
Hello
By adding a checkbox control to the results of QueryRegion Table.
The search page is to launch error
The search cannot be performed because the table has pending changes that would be lost.
First search is performed successfully, but when we are once again, we get the error
The search cannot be performed because the table has pending changes that would be lost.
When I remove the box and change to any point of the image or switch the search works very well.
but when I use the checkbox iam getting the error above
Results table contains research request only.
Can someone explain why we get this error
How to overcome the problem.

and I guess that the box has a transitional attribute.Now, in the setter of the transitional attribute in VORowImpl just use populateAttribute method
instead of setSttributeInternal.public void setSelectFlag (String val)
{
populateAttribute (SELECTFLAG, val);
}polateAttribute is not the original Version as dirty.
This will solve the problem.

Repeated cannot find symbol errors
Hi, I'm a newb at blackberry JDE and java in general. I'm used to working to loosen typed and extended as php environments. I'm creating a simple application tasking to teach myself State and management of the data and other. I've made very little progress and I am already stuck. I looked through the blackberry API tutorial resources and searching the forums, but have been unable to find answers (probably seen them and just he did not know that I am so lost). I met two roadblocks in the following code, which intervened in the section highlighted with #. The following class is called by a class of application and built and tested successfully, without the sharps.
1.) whenever I try to add whatever it is inside the class ButtonListener (by adding the code in force, that is), as a string, call a method or try to push something to the front of the battery of the display, I get the error 'cannot find symbol' during compilation. I guess it's a problem with the legacy of some sort, but I am totally lost and frustrated.
2.) once it's resolved, I want to insert a switch statement where the # is to add and remove items from different field of the display depending on the value selected in the ObjectChoiceField itemTypeField. I think, I need to set the index of the choicefield initially and then retrieve it later, but I don't know how.
Any help will be greatly appreciated.

I have a website, the pages of movieclip interpolations (named home, bio, music, video and contact). Love the effect and tried to keep it. Main scenario contains the main buttons (home_btn, bio_btn, music btn, video_btn, contact_btn). Music page has an XML mp3 player it with the button control. Video page has a video encoded without code.
I need the following:
1 - music and video to be cut as the tween pages/movieclips offstage. Gets boring with them playing mostly at the same time!
2 - music player to play properly. He's not with the new code.
I have the following code. The "Code in 'tween' is on frame 1 of the main timeline of the movie. The 'MP3 code' is on frame 1 of the music clip. I get the error message after running my film. I ran the debugger I publish and point it to music.my_channel.stop (); to the code below. My thought process on this was that it reach out to music movieclip, find my_channel and stop him. Also, my MP3 player does not work as a result of this new code.

"Cannot display page" error message when you try to download 2010 professional
Original title:
Error message on Internet download from trusted sites?
I am trying to download 2010 Professional on my computer. Yes, I have a product key. Whenever I try to download, I get an error message "cannot display the page. This often happens to me. Any suggestions?
Hello
Thank you for giving us the opportunity to help you with your concern for Windows!
I see from the description of your post, that you are unable to download Microsoft Office Professional 2010.
If you get the error message in Internet Explorer , then this might be the cause:
For performance reasons, where Internet Explorer cannot establish a connection to a proxy server, the proxy server is added to a list of proxy servers bad so that it is not reused for a period of time. This period is 30 minutes by default. If a proxy auto-configuration script returns a PROXY list that specifies several proxy servers, a connection to the proxy in the list will be attempted. If the connection fails, the process is repeated until a connection is established, or the list is exhausted. If the list is exhausted and no connection is established, the user will receive a "Cannot display Page" error message in Internet Explorer.
We would like to get more information about you to help solve your problem. You better, please answer the following questions.
1. What is the full error message?
2 are you able to download other files without any problem?
3. what web browser do you use to download?
4. what version of Windows are you using? What service pack is installed on the computer?
5. based on what site are you trying to download?
