• All tables and xml are be NULL problem

  Hello guys

  I'm working on a project that uses the format of loading xml, e4x and intensively, table manipulation and it was fine but now I'm stuck on a strange problem.  All code was beautiful and application work and respond in a desired way, but then mystourisly it stopped working and started to return NULL values in almost all the tables of the (internal) actionscript and XML varibales.
  
  Now every time I have to load the xml file and set the loaded xml internal variables, internal values get only NULL instead of data.
  The same is the situation with the berries, I created a few components in mxml, and when I passed them to reference tables, the code gets compiled successfully, but again Array has only null values [that code worked very well too]

  Thanks Larell

  You can use an absolute path, but the chances of error are much greater than when you use a local path.  In addition, your absolute path does not work when you deploy your swf (on a server under an air or as a file of projection).

  Use a relative path.  the easiest way is to put the xml file in the same directory with your html and swf, fla.  You can then use:

  yourxml. Load ("icons.xml");

  I like to keep xml files in a subfolder of the xml file that contains my html and swf, fla.  in this situation, you would use:

  yourxml. Load("XML/icons.xml");

  but whenever you have a path problem, the best bet after a few checks and emerge from the spelling is to the file to be loaded into the same directory as all flash files and make sure you can get this to work.  then start moving files to create a cleaner more logical Setup, if that suits your needs.

• DataGrid and &amp; quot; change &amp; quot; the event, called 2nd time problem

  Hello
  
  I have a datagrid and I use the attribute 'change' to call a function when you click on an item in my datagrid. I use the change attribute because I still want the columns to sort by the column header. In any case, it works the first time around, but if I click on the same element in the list, it does not yet have my function.
  
  When you click an item in the DataGrid I call the 'navigateToURL()' method and it works the first time, but when you click on the same item in the datagrid control, which is not, I guess he thinks there is no change happening so it does not have the function to call. He's right there.
  
  Any help appreciated.
  
  -WestSide

  try to use itemClick

  public void clickItem(e:ListEvent):void {}

• akwardness DataGrid and onclick

  Hello
  
  I have an onclick on my datagrid. When you click the scroll bar in the grid if its there and or column header (sorting) she calls the same function. I understand that both are events click on the grid, but the scroll bar, which seems to be an area on the data grid that shouldn't be my function to call.
  
  In addition a kind being a click, how can we get around that, I would like to have both the onclick on my datagrid and still be able to click to sort.
  
  Thank you

  If you want to detect someone by selecting a line on your datagrid, use the change, not the click event event.

• DataGrid and TitleWindow - problem clicking on header called TitleWindow!

  Hi all
  
  I'm really puzzled by the present, any help would be greatly appreciated!
  
  I have a DataGrid and a TitleWindow. I've been using a 'click "command in the DataGrid is click ="launchViewer (event)".
  
  This is the code for the launchViewer:
  public void launchViewer(event:MouseEvent):void
  {/ * Function launchViewer * /}
  var popUp: ViewWindow = ViewWindow (PopUpManager.createPopUp (this, ViewWindow, false));
  }
  
  
  But now I find that if I click on the headers to sort the columns of the datagrid the TitleWindow is called as well! Is there a way to recognize that if I click on a column header the TitleWindow function will not be called?
  
  I tried to use mouseOver, but this error occurs:
  TypeError: Error #1009: cannot access a property or method of a null object reference.
  
  Help, please!
  Thank you very much
  Tanz

  Here I have a solution that worked for me:

  I used the Exchange = "dgClicked (event) call" instead of click ="launchViewer (event)" in the defintiion of Datagrid.

  DgClicked function rank controls the clicked cell was. If row 0 (header) was clicked then do a normal sort - that is, do not call the TitleWindow popUp.

  public void dgClicked(event:ListEvent):void
  {
  If (event.rowIndex! = 0) {}
  launchViewer (event);
  }
  }

  The definition of launchViewer also supposed a MouseEvent to a ListEvent:
  public void launchViewer(event:ListEvent):void
  {
  var popUp: ViewWindow = ViewWindow (PopUpManager.createPopUp (this, ViewWindow, false));
  }

  I hope this helps someone else out there!

• PL/SQL and XML

  So I have a little problem. I have a request that I need to have to produce XML from. I was initially doing this through htp.prn, but then I realized that some of the data that I was out to and XML file may have special characters in them, namely signs and double quotes. I decided to see if Oracle were all functions to remove special characters and replace them with the HTML counterparts (an ampersand would turn into & amp ;)) I found a few things that seemed useful, but the problem is, with the functions I found, he wanted the data to be strictly out of the database and some of the data I wanted in the XML document was also user entered on the pages. Is there something out there that will search by text AND query results to check that there are no special characters? Thank you.
  
  -Joshua

  The following function should work for what you are trying to do.

  htp.p(htf.escape_sc(:P1_ITEM));
  

  To escape the database columns simply include in your select statement:

  SELECT htf.escape_sc(COLUMN_NAME) alias
    FROM TABLE
  

  To escape from the elements on your page apex:

  INSERT INTO table
             (COLUMN_NAME)
       VALUES(htf.escape_sc(:P1_ITEM))
  

  Good luck

• N000bie - woes headerText DataGrid and data...

  Hello

  So, I have not worked with before DataGrid so far; what I'm trying to do is to enter the data of the first line of xmlDP, '< team >' and uses these attributes as the column headerText property (for example: 1. Chk, 2 Nam0rz, 3 medium, etc...). I can get it going, but I can not insert my data once I have change the col.headerText. through addColumn. See the comments in the code below for more than a description, but considering how the DataGrid control is a new paradigm for me, I know that I do this wrong of all.

  If anyone can help me tame this code together in order to achieve the desired result, or explain how best to build the code below in order to get the desired result, I appreciate it.

  Thank you muchleh,

  which is not sensible to what you say in your first post and it makes no sense watching the player xmllists.

  Looks like you want the name of the attribute of the players to be column headings.

  Try this:

  var colA: Array = ['checkBox', 'name', 'avg', 'data', 'data2'];

  aDg.columns = colA;

  var dp:DataProvider = new DataProvider (xmlDP);

  aDg.dataProvider = dp;

• Problem with spark list and XML dataProvider

  I am VERY new to Flex so I'm probably doing something wrong, but I hope it means this will get a quick response.

  I use a list of spark related to a data provider. On the actions of the user, the list will be filtered. The problem I encounter is that when the xml result is one, she will eventually launch an error:

  Has no type constraint: cannot convert mx.utils::ObjectProxy to mx.collections.IList.
