Extend Datagrid with unsorted view

Hi all,
my datagrid displays in the 'default' unsorted view. Then users can choose a sorting order.
A customer also needs the default unsorted view after he has choosen a particular sort order on a certain column (without refreshing the page).
However, once choosen a sort direction, the datagrid only have the asc/desc sort directions.
Do I need to extend the datagrid or can this be done easily ?
thx.

Seems odd to have the same DG show one column in a different sort order,
even unsorted.
You could determine the row index from
var index:int = DataGrid(owner).verticalScrollPosition + listData.rowIndex
and access dataProvider["source"][index];

DataGrid with styleFunction example posted

I've just uploaded a new example to my site, which is an
extended DataGrid
with a styleFunction added similar to the one that
AdvancedDataGrid has.
This also includes a StyleableRenderer class, which is a
simple itemRenderer
that extends UIComponent, if you've been wondering where to
start in order
to start writing your own UIComponent based itemRenderers.
http://flexdiary.blogspot.com/2008/09/extended-datagrid-with-stylefunction.html
Enjoy!

Hello
First, thank you for the help. I later had the same idea with the base class. Know there is some problem with the database. But that's an other problem.
So thanks for your help!
Actually I'm not sure which DataGrid I'm using. I'm quite sure it's not MX, Because I can't find any MX-Code. The DataGrid gets created with a function in its own class. (EntityDataGrid.as)
I do not get any error. The other objects just don't get viewed. (There is an exception rule)

DataGrid with dynamic columns & renderers

I'm developing using Flash Builder 4 & Flex SDK 4.1.
I need to manage very dynamic DataGrid components and keep their definitions, which are all part of a complex item renderer of an Offers list.
The objects structure is simplified as follows -
Data: Model --> Offers ArrayCollection --> Offer VO --> DataGrid data ArrayCollection & DataGrid columns Array
View: List --> Offer Item Renderer --> DataGrid
1. Since the DataGrid's columns property accepts only an Array (not ArrayCollection), it seems like Data Binding for defining the columns is very problematic.
I tried to bind it to the source property of an ArrayCollection that would keep my columns definitions, but it didn't really work (mainly header display bugs).
What is the recommended way to keep the dynamic columns definition of a DataGrid?
2. Each column can have a set of dynamic properties, so I created a "mutant" - Column VO that extends DataGridColumn and got a dynamic properties ArrayCollection on it.
The columns got a custom header renderer that includes an icon when there are properties.
The header renderers got 4 main states (NotSelectedWithProperties, SelectedWithProperties, NotSelectedWithoutProperties & SelectedWithoutProperties).
However, the header renderer area seems a bit buggy when maintaning dynamic columns.
Any thoughts on the subject?
3. Anyway, I ended up recreating the DataGrid's columns Array very often (copying the columns definition on the offer's item renderer's dataChange event handler).
Note that the dynamic properties can be edited when the column is selected and I copy their values from the view back to the model when entering the state NotSelectedWithProperties.
This feels way too complicated and I really try to keep it simple, inspite of the required complexity.
Does anyone have better ideas?
4. In some cases the column's item renderer should also be modified into another DataGrid (grid-in-grid).
I used the MXDataGridItemRenderer with a DataGrid and included an ArrayCollection for the "newValue" returned by the editor.
(I use RendererIsEditor=true and on updateComplete populate that variable with the DataGrid's dataProvider contents)
When needed, I loop though the data objects of the parent DataGrid and populate the related field with an ArrayCollection of key-value objects that are displayed on the internal DataGrid.
After adding this feature I encounter very strange bugs -
a. After editing the grid-in-grid values and changing the column's state (selecting & deselecting), I get the following exception:
ArgumentError. Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/setChildIndex()
at mx.core::UIComponent/setChildIndex().......6993....
All I could find about this is that it might be related to some context error or something, but I'm really stuck on this one.
b. Sometimes another column might copy value from one row to another, running over the previous value.
I'm not sure exactly what sequence of actions causes this behavior, but it's related to that itemRenderer for sure.
c. Switching places with a column that uses the grid item renderer (headerShift) causes a stak overflow of StyleManager that tried to get style from the DataGridItemRenderer. This one I just found out, but couldn't reproduce a second time... strange!
I'm pretty sure this caused another problem that I don't remember at the moment.
The bottom line is that there got to be a better way to implement this feature within this already-complicated environment.
Maybe I'm doing something very wrong here...
Please advice and thanks for reading all this.

Update on item 4a -
This was a major issue (the main reason for opening this thread really) and I managed to resolve it!
As part of my application, I override the default DataGrid behavior for column selection (headerRelease event).
Instead of sorting, I change the column's header looks and define it as Selected (for showing its dynamic properties and enable its deletion).
At first I did this by setting styles, but the look didn't refresh unless I created a new instance of the header renderer.
Later I changed thi behavior to work with states, but I left the new header renderer instance creation commands and those lines created all the mess!
Conclusion -
If you define a custom header renderer for your datagrid column and then a custom item renderer, don't create a new instance of your header renderer!
It would still be nice to get some response for the other issues I raised.
Thanks and have a nice week.

Extending component with code behind

Hi,
I have read an article about extending components with code
behind:
http://www.adobe.com/devnet/flex/quickstart/building_components_using_code_behind/
I have a question about that. Maybe someone can help me.
Example:
{components/CartClass.as}
package components
public class CartClass extends DataGrid
public function CartClass()
super();
{components/Cart.mxml}
<?xml version="1.0" encoding="utf-8"?>
<shop:CartClass xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:shop="components.*"
>
</shop:CartClass>
Everthing works fine but when i add:
<mx:columns>
<mx:DataGridColumn headerText="Title" />
</mx:columns>
between the shop:CartClass tag, Flex says:
Could not resolve <mx:columns> to a component
implementation
Anyone knows why?

columns is actually a property of the DataGrid instance,
rather than the
DataGrid class itself, so it needs to be in the same
namespace as the actual
DataGrid subclass:
<shop:columns>
<mx:DataGridColumn headerText="Title" />
</shop:columns>

Combobox in Datagrid with different values

Hi All,
I have a datagrid. One of the columns in the datagrid is set
to display a combobox as the ItemRenderer. Now, the data for the
combobox is different for each row. How do I set up the data
provider for the combobox in such a scenario.
For example : I have a collection of Shirt objects.
public class Shirt {
public String id;
public String type;
public String[] color; //this is an array
This should be displayed in the datagrid, with the Color
column rendered as a combobox. The colors will be different for
each shirt.
Thanks
CS

Yes. Some more detail:
in the function,
override public function set data(value:Object): void {
the "value" parameter will contain a refernce to an entire
"Shirt" instance.
So you can assign the comboBox.dataProvider=value.color;
Now, It is more complicated than this, because you will want
the combobox to show the correct value for each row, right?
For this to happen, you will need a selectedColor property on
Shirt. When the user chooses a color, you will need to update this
property with the selection.
Next, your renderer must read the value of selectedColor and
set the comboBox.selectedIndex.
If selectedColor contains the *index* of the color then you
have it easy. If it contains the color name itself, then you will
have to for-loop over the color array until yom match the
selectedColor. then you will have the index and can set
selectedIndex.
ComboBox does not support setting the value directly. It is
pretty easy to extend combo to do this. There are several examples
out there. I posted a link to one on CFLEX.net

TS1381 My left arrow does not work on my macbook pro(model A1226). I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, test all other keys with keyboard view (all others work) - HELP!!

My left arrow does not work on my macbook pro(model A1226).
I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, & tested all other keys with "keyboard viewer" (all other keys work except for the arrow).
In addition, I have gone thru all the recommended checks with universal access and have booted from snow leopard dvd and the left arrow still does not work.
I have tried using the left arrow key in all of applications I use such as: excel, ms word, address book, calendar, iphoto, terminal, & highlighting an icon and using the arrows to move to another selected icon.
Here is the kicker! In addition, I purchased a logitech solar bluetooth keyboard and the arrows work fine with my ipad but do not work when paired with the macbook pro. All other keys work fine on the macbook pro using the bluetooth keyboard.
I believe this says that the problem is not in my macbook pro keyboard. So where can it be?
Can anyone think of any other rabbit holes I can search?
thanks and regards

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

[SOLVED] Lousy fonts with .chm viewer for Linux

I installed the .chm file viewer HelpExplorer 3.0 in both Windows XP and Arch Linux (chm = compiled HTML help file). In Windows XP, with default fonts installed, the fonts in text read with this viewer appear crisp, sharp and anti-aliased. In Arch with KDE 3.5.7, on the other hand, the fonts appear fuzzy, grainy and don't seem to be anti-aliased, in contrast with their appearance in all other apps (except for a few such as Dillo) which render text good-looking, sharp and anti-aliased.
HelpExplorer for Linux was provided as a tarball that included a precompiled 'helpexplorer' binary. The program doesn't seem to allow for customizing font settings.
The following fonts are installed in Arch (in /usr/share/fonts/):
ttf-bitstream-vera-1.10-5 is installed by default
gsfonts 8.11-4 is installed by default
PostScript Type 1 fonts installed: Century Schoolbook, Nimbus, URW Bookman, URW Gothic, URW Palladio
ttf-ms-fonts-2.0-1 (Microsoft TTF: Andale Mono, Arial, Comic, Courier, Georgia, Impact, Tahoma, Times New Roman, Trebuchet)
font-bh-ttf-1.0.0-3 (Luxi BH)
xorg-fonts-100dpi-1.0.1-1 (courier, helvetica, lucida, new century, times)

What do I need to do to improve the font appearance in this program in Linux?
Last edited by RobF (2007-10-02 18:06:46)

I found a solution of sorts by installing and running the Windows version of HelpExplorer in Wine or Crossover. There is still very little control over fonts but when I enlarge the default font (with 2x CTRL-+) I do get a nice-looking anti-aliased Times New Roman font, and this solution would be my preferred way of reading .chm files in Linux (i.e. better than KchmViewer or Xchm).
Recap of the problem:
1. The .chm viewer HelpExplorer Viewer 3.0 when installed in Windows XP renders fonts crisp and clear and anti-aliased.
2. The Linux version of HelpExplorer Viewer 3.0 (delivered as a precompiled executable in a tarball) doesn't render fonts antialiased, regardless of what I tried, and they look grainy and unattractive.
3. The Windows version of HelpExplorer Viewer 3.0 when installed and run in Arch in Wine or Crossover does render the default font they offer (looks like Times New Roman) fairly crisp and clear and anti-aliased, at least at the enlarged setting.
Can someone explain to me what might be going on? Why is it that the Linux version cannot render fonts anti-aliased when the Windows version running in the emulator in Linux can? Is there something that I have to change in my fonts config, fonts location, symlinks or path to get the anti-aliased fonts to work in HelpExplorer in Linux?

Master-detail with dynamic view object

How can you create a view link with a view object that is dynamic? I have created a master-detail relationship on a UIX page. I change the master view object at runtime using a view definition and SQL and then I bind the view object to an iterator on a UIX page. I need the new dynamic view object to maintain the link between the detail view object. Is this possible?
The reason why I have to change the view object at runtime is because I am implementing a search module and the tables in the from clause can be modified at runtime so I need to have a dynamic view object.
Thanks,
Sanjay

After playing around with ViewObjectImpl's setQuery() method some more I found out that this solution might not work for me due to the following reason: when the user tries to sort a column in the result table, the original contents of the view object get executed instead of the run time query.

I would like to go back to my original solution that included creating a view definition based on the runtime query and then creating a view object from that which I bind to the RowSetIterator. The missing piece to the master-detail functionality is with the detail Iterator being in sync with the master. I have tried the following but I get a ClassCastException 
DCIteratorBinding detailBinding = ctx.getBindingContainer().findIteratorBinding("DetailIterator");
detailBinding.getViewObject().setMasterRowSetIterator(masterBinding.getRowSetIterator());

here is the relevant stack trace:
java.lang.ClassCastException

ICal bug with month view

I primarily use week view on iCal, but sometimes i switch to month view for a larger perspective. Often, i use month view to check for any leftover events from the previous month in case i forgot to delete one or two.
I just found a bug concerning this. If i click on "month" today, it'll take me to the month view for june 2011, and from there i can navigate forwards or backwards. However, may 2011 seems to have a bug. If i click on < from june, it does nothing; if i click again, it takes me to april 2011. Similarly, if i click on > from april it does nothing and if i click again it takes me to june.
It doesn't end there. The june/may thing happens only when the selected day (the one shaded light grey on the month and week views and bright blue on the little month tab on the left) is after 04 june. If a day from the first week of june (i have my weeks start on sunday) is selected, the < button does take me to may, but several events which i deleted a long time ago are showing up.
Now, i have an event set for today (04 june). Since the first four days of june are in the same week as the last three of may, the month view for may shows these four days, as any normal calendar app would.
If i use the month tab to the left to navigate, i can access may 2011 by selecting any day on that month. However, iCal's behaviour depends on which day was selected previously. If the previous day was in april 2011 or earlier, iCal will show the month of may completely empty, which is great because i have no leftover appointments from may; however, the box for 04 june is also empty, which it shouldn't be. If the previous day was in june 2011, it'll show may with a repeating event on every sunday except the first, which is completely absurd, since i have deleted this event (and why isn't it showing on the first sunday in may?); the box for 04 june, however, will correctly show the event i have set for this day. If the previous day was in july 2011 or later, it'll show may with the repeating event on all sundays (including the first one) and it won't show anything on the box for 04 june.
Obviously, there is a bug with may 2011.
In case it helps, i do have a repeating event set to all sundays until the end of existence, but i have deleted all the entries from may and previously, since they have obviously already happened. Also, i had many other repeating events set to happen on different weekdays; these are to repeat themselves weekly until about halfway through june, and they started on april or may (can't remember right now). Like the sunday one, i have deleted all the entries from may because they have already taken place. Strangely (and thankfully), none of these appear when i visit may from june or later, as does the sunday event.
Any help would be greatly appreciated. Or am i forever stuck with week view, which has so far proven to be bug-free?
(I did a search on Google and another on the Apple forums for this issue but could find nothing, so i decided to ask the question myself. I apologise if somebody has already asked this question and i just couldn't find it.)

Greetings,
I have a vague recollection of someone else with this issue but haven't experienced it myself nor encountered it recently.
Troubleshooting:
1.) First make an iCal backup: http://support.apple.com/kb/HT2966.
2.) Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical and / or "ical"
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
__NOTE: Removing these files will remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
Once the computer is back up and running open iCal and test.
Hope that helps!

Problem with a view in XK01 transaction

Hi All,
I am working on upload conversion for Vendor Master. While doing conversion, i am getting a problem with a Contact person view in XK01 transaction. In contact person view the telephone field column sometimes allowing to add data ,sometimes it's not allowing data which results an error in conversion program saying that the telephone field in not an input field. I don't know why the view is showing the telephone field like that.
Can any one suggest the solution for this problem. I know this is configuration problem with a view but i posted in ABAP forums.
Thanks

Hi Ben,
I assume that you are writing a BDC program to upload contact person information. If so, you are trying to populate a table control here. Please check to see if you are calculating the index to assign values to the correct rows.
if you are calculating index in your program then i think it should be configuration problem as you said.
Thanks,
Ganesh.

I bought a brand new Mac 27" desktop that came loaded with Adobe CS6. Everything worked like a charm until the hard drive, 1Tb, developed a bad sector and the Apple Store reinstalled a new one as I had extended warranty with them. They recycled the drive immediately (like a fool I didn't ask for it back to get the data off it.) But luckily I have all my data on CrashPlan. I downloaded it and it worked great except I downloaded it to the desktop and not the original location so it got squirrely. I also have an external 1.5Tb drive that I wanted to make bootable so I installed Mavericks 10.9.3 . I then went ahead and installed it on the newly installed drive too.
I think that because I have a new drive Adobe thinks I have a news computer. I bought the 27" Mac brand new from Ebay and it came loaded with software, including CS6. I have a serial number for CS6 but Adobe said it wasn't valid. (I have owned CS2, CS4 and now CS6 which came preloaded onto the Mac by the seller who told me that the software was registered to the Mac???
I am going to re-download the backup but this time to the original location (I still don't think it will work with Adobe. What can I do about this?
