itemFocusOutHandler with DataGrid editable selected point question
Hi all, I'm relatively new to Flex and I have a question that is generating a lot of frustration. I'm sure that the solution is string me in the face, but I just can't see the forest for the trees.
OK, I am trying to achieve a data grid that is populated with data based on a one-to-many relationship between the people and the courts with a join to show people that do not have assigned courses and then assign these by date if necessary.
It is action of itemFocusOutHandler where the database is then updated with the selected data grid component.
Question: when you're away from the cell update the triggering event and the database is updated with the selected new row and not passed. I expect the update to trigger until the selected element is change, but it doesn't seem to be the case.
Example of
Added to John on the 24th courses
Tab to Jason the selected item changes, and Jason is added to the database with no entry. ALSOM If then back to John of Jason, the database will be updated with data for John
View database:
Table_ID | CourseHeader | Date | Person_IDHeader 4 |
---|---|---|---|
1 | 28/10/2010 | 2 |
Where the person is equal to
Table_ID | First | Last |
---|---|---|
1 | John | Smith |
2 | Jason | Holmes |
You are willing to provide any help will be very appreciated.
And the code (I tried to simplify this if possible):

Thank you again...
If your topic says Manager itemFocusOut, implies that you are using a
event Focusout/focusouthandler(). I did not read the code that carefully.
Verify that the selectedItem has already changed. Maybe he has. You
must be able to use the information in the DataGridEvent to access to the
data item that was published.

Suddenly this week 7 Windows has stopped working and the error message said I might have a non-genuine copy, etc. I checked the product key by using the Start/computer/properties menu. The product key was not the same as on my PC, so I tried to get the right version. Then I got the error message that you have entered the product key will not work with this edition of Windows 7, and I want to run Windows 7 set up or enter a professional product key.
I saw that someone else had been advised to run MGADiag.exe so I've already did but am puzzled by the report. And I'm worried, why me nice Acer desktop PC suddenly did that, when he had worked happily with normal updates etc. The report shows a different product to the label of my PC key.
Can someone help, please
Thank you

As a plug-in? I have problems with an editable IRS form. It gives me "Access denied" and then opens the file as an editable file. I was able to open the form in the library.
I found a few other questions on this forum who have remained unanswered. I found a site citing the problem for drive X - I use XI.
Change to drive XI. Perhaps the reader at the library had this as its default setting.
- In Adobe Reader, clear the check box enable the Mode protected at startup :
- If you have a PDF open, right-click the document, and then click Page Display Preferences.
- If you open Adobe Reader from the shortcut, click on Edit > Preferences.
- In the categories dialog box Preferences pane, click (enhanced) protection, and then clear the box enable the Mode protected at startup .
- Close and reopen Reader.
I have no idea if that setting has been changed in my XI player since I used this version exactly one year ago.

Cannot see the whole picture when you move into a smaller template with the direct Selection tool
Hello!
I recently got my laptop cleaned in preparation for examinations and such (I'm in high school). As I belong to art class, when Basic programs have been re-installed we also got the Adobe programs, but we got the CC 2015 version instead of the version CS5, we had earlier. After a stressful week, I finally had time to sit and work on my projects aside, but I quickly found a big problem which stops at my work. After re size the image at the size I want, I don't see the whole picture when I move in the smallest area with the direct Selection tool more. Photos I use are generally quite large, that I've tried to work with now are 451mmx338mm after the scaling down and I have a 'framework of standard departure' to 60mmx15mm (I make the bosses), so now I have basically has to guess my way toward a good composition...
Can I make it work again?
Click on the image and hold the pointer of the mouse for a while. And then drag.

Access to library and store SDK API with simple editing?
Hello
We just started to evaluate the DPS for our first project.
In our project, we want to access the device ID and send it to a server. Apparently, the library and the store SDK provides this feature (DeviceService).
My question is now:
We can access this SDK with the single edition of DPS? Or do we need the professional edition or enterprise to use this SDK?
Thank you!
Best
Matthias
No, there are specific features of business of DPS. Library and store SDK cannot be used with simple edition or Pro of the DPS, so you'll need to get the company DPS to use these features.

The drop-down list changes color with background option selected
Hello!
I m stuck with this drop-down menu that I need to have a red background, if the TBD option is active (which is the default) and have no backgrond if no other option is selected.
The red background is a red rectangle that is visible or hidden, I have all code in the event of modification of the drop-down list:
if (this.rawValue == "TBD"){ RectangleRed2.presence = "visible"; }else{ RectangleRed2.presence = "hidden"; }
But the thing is that the event checks the value when is changed, so if I'm in the value of TBD and I selected point 1, the recntagle is still visible, because at the moment, I have chosen point 1 value was to be determined, so does not in the way I need to.
Anys ideas?
Thank you!
You must use
if (xfa.event.newText == "TBD"){ ...
Then it works fine.
"xfa.event.newText" evaluates to dropdown in the runtime.
Hope it is useful,

With Standard Edition database DB from Enterprise Manager management packs.
Hi all
As far as I know Enterprise Manager 11g is free to install, but not management pack.
I want to install 11g Grid control in my environment but I got all my oracle Standard edition databases.
So my question is that:
Which one would use one of the following management pack in my Enterprise manager 11g grid control environment?
Below is the text copied from EM 11 g Documentation
Enterprise Manager offers the following packs of the Oracle database:
Pack of diagnostics for the Oracle database.
Tuning Pack for Oracle Database+.
Management of change for Oracle Database pack+.
Configuration Management Pack for the Oracle database.
Provisioning and Patch Automation Pack for Oracle Database+.
Hide data Pack for Oracle Database+.
These management packs can be purchased only with Enterprise Edition. The features of these packs are available through Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control and API provided with the Oracle database software.
Thank you very much
HemsNot exactly, but you can not register with anything other than Enterprise Edition management packs.
You can continue to use the Grid control to monitor the availability of database and server and perform tasks to others, but the features available in these management packs (as the 'Performance', or patch management tab and so on) will not work. It still provides a value without these packs.

Why don't I have easily select my questions open after the connection support?
When I connect support communities, I have still no clear idea where to find my support questions which remain open to check updates.
Seems to me that this should be a great, distinct and separate button on the homepage of support after you have connected. "My open issues Apple Community Support."
Is this too much to ask?
