N/A in DataFields

Hi all,
When I map a domain class to a datafield, the field will
show N/A when the domain class has a NULL value. I
want it to show something else, like 'Empty' or 'Not filled
yet' or nothing.
How do I do that?
Overriding 'FillString' will let me format the value to any
string I want, but 'FillString' will nog get executed when
'IsNull' is TRUE.

Patrice,
OK, that is one viable option. But what if I want 'Empty' in
one window and 'N/A' in another?
Pascal.
Pascal,
to replace 'N/A' by whatever you want, you only have to :
- decompile the message catalog $Forte_Root\install\nls\fortemsg
(see Forte system management guide for utility Compmsg).
- edit the .msg file created by compmsg utility
- replace the string # 126 in set # 1 ('N/A') by another
(type a blank character in you don't want anything, not a nil).
- recompile the message catalog, replace the old by the new one,
shutdown Forte
- start a brand new Forte session, and enjoy the new string...

How to Sum the datafield of a sub-group?

Post Author: [email protected]
CA Forum: General
Hello guys,
I am having this issue that I want to only Sum the datafield at sub-group level, not the detail level. But when I do the sum, it is adding all the details. The reason I am having this is because I have somewhat duplicated details (they complement each other). I merge them using group (by Item). The Item QTY is the feild that they all have and they have the same value, but I only need one of them. Now I want to group them by order number and show the total of items I ordered. I Sum all the items' QTY, but instead of sum the QTY that's merged, it sums all the QTY from detail. Basically I am suming duplicate numbers.
Is there any solution to this? Thank you.

CA Forum: General
Hello Jagan,
Thank you for the help. I treid the Average running total, but the problem is that I cannot do Summary on those new fields on the parent group. Also I can't get rid of the dupliate because the singel record does not contain enough info, I need all the records to merge togather to collect all the required inforamtion. Before I will just created a merged view on my DB to get rid of duplicate records. But this time, I am linking too much tables (includes external server DB table) that I can't make a view for that.
Basically I have an order that splits into multiple invoices that get shipped using an external server where the Actual Ship Date does not write back to our own ordering system. I am trying to see if all my items are ship on time. So I need to merge all the items QTY from invoices that linked with external shipping DB, and group them in one order.
The main problem I have is that I can't do summary on many custome fields. I can made the correct amount using Formula Field that has a shared flag to not include duplicate numbers. But once I use the shared flag, the forumla is no longer useable by Summary.
Anyway, I think I will just use Excel instead. I already have all the proper data, just that when I do group summary in Crystal, it becomes a problem. I will export the data and do analysis from there.
Thank you for the help

Using a canvas as an itemrenderer - how to access the datafield?

Yes... another ItemRenderer related question...
So I have this advancedDataGrid of which I dynamically
generate the columns in actionscript. Each of these columns get
their own datafield.
This code works well, since all the data displays nicely
where I want it to be.
However, in the columns there are numbers from like 0 to 10,
these are put there by the default itemrenderer by using the
datafield. Instead of just displaying these numbers, I'd like to
use a canvas as an itemrenderer to draw something in the box based
on the value of the number. So all I need to access in my Canvas is
the value that is parsed by the datafield.
I thought to do so by overriding public function set
data(value:Object):void
But what does value contain? I tried doing something with it
but I keep getting errors. Does value just contain the entire
dataProvider? Or is there a way to acces just the number that would
be put on that position in the grid if I wouldn't be using a custom
itemrenderer at all?
I've searched tons of blogs but haven't found the exact
answer to my question yet.
Many thanks in advance.

It contains the information needed for the entire row. Just
put a break
point in the code in your override function and then run the
application in
debug mode. Use the variables window to inspect the value.

Are the errors related to the value or are they related to
something else,
such as trying to set properties on subcomponents that have
not been
instatiated yet.

Look at implementing IDropInListItemRenderer and then look at
listData.label.

RE: DataField, update underlying data via TOOL,Express

John,
does it work if you mix the "CopyfromClipboard" method with the "PlaceValueinDisplayedField" ?
If this is not the correct solution to you problem, could you please specify "where" it does not work ?
Thanks a lot indeed.

Subject: DataField, update underlying data via TOOL, Express
In TOOL code we PasteText() into a DataField, but the underlying data
object does not get updated until the user interacts with the GUI.
That causes problems if we need to use the underlying data object's
value immediately after the paste. How can we:
force an update of the underlying data object and
ensure that the update goes through before our method call returns,
i.e., ensure that if the update is via Forte events, those events
are handled before returning.
The context is a calendar lookup button that pastes into an adjoining
DataField.

Well, I think I have answered my own question, but I will leave it here in case anyone else has the same problem.
So, as far as I have been able to track down, it all went wrong when I was running through the connection wizard.
Under the section titled "Creating the Data Source" is describes how to find your database file and create the appropriate connection string. However, on my version of VS Express 2010 . It offered me a prompts , saying something like, "would you like to
move this database file into the application directory and change the connection string" this sounded very sensible to me, so I said yes.
All proceeded accordingly. And the database file now appeared in the solution explorer.
The app config file said that the connection string was
Data Source=|DataDirectory|\Database1.sdf"
I presumed this would be interpreted correctly by the rest of the app, as it was generated by VS.
But it didn't, what I cannot understand is how no error was generated. And data seemed to pull
into the bound controls.
But I have been testing it for a while now. and it seems that if I manually override the config file with the actual directory where the file exists , then there is not a problem. Data is retained in the file
This is more of a VB.net question, but I couldn't find it in the drop down. I will try and move it there now
Thanks guys for your patience.
p.s. RSingh , the code I posted above did come from the SaveItem_Click event
handler

Access DataField in Itemrenderer when submitting to Database

Hello,
I'm really stuck on this one. I have setup an Itemrenderer in a Datagrid which manages a DateField. Users can enter a date and other values directly in the datagrid. When they click 'submit', I want to populate a row in a database and I have setup a service for this. A row is created in the db as expected however the date is not populated despite users having entered a value. Below is a code snippet:
Datagrid
<s:GridColumn dataField="datf" headerText="Period From" rendererIsEditable="true">
 <s:itemRenderer>
 <fx:Component>
 <s:GridItemRenderer dataChange="updateRenderer()">
 <fx:Script>
 <![CDATA[
 public function updateRenderer():void {
 periodFrom.text = outerDocument.dtf1.format(data.datf);
 private function dateField_labelFunc(item:Date):String {
 periodFrom.text = outerDocument.dtf1.format(item);
 return outerDocument.dtf1.format(item);
 ]]>
 </fx:Script>
 <mx:DateField horizontalCenter="0" verticalCenter="0" width="90%" id="periodFrom" labelFunction="dateField_labelFunc"/>
 </s:GridItemRenderer>
 </fx:Component>
</s:itemRenderer>
</s:GridColumn>
Handler
protected function createBillResult_resultHandler(event:ResultEvent):void
 var dataProvider = itemsDg.dataProvider;
 var item = null;
 for (var i:int = 0; i < dataProvider.length; i++){
 item = dataProvider.getItemAt(i);
 trace(item.datf); <--- THIS IS 'UNDEFINED'
 billItems.days = item.days;
 billItems.ratu = item.ratu;
 billItems.lnid = item.lnid;
 trace(billItems.datf = dtf2.format(item.datf));
 createBillItemsResult.token = billingService.createBillItems(billItems);
I would have thought that I can access the value from the itemrenderer using the dataField property like I do with the other items.
Please, please, please help.

Keep certain text in a datafield together when it is divided in more lines

Hello,
I have a datafield 'U_ketel_verw'. The field is set as Allow to grow. What I like to realize is that certain text in this datafield is kept together.
This is my exemple:
It looks like this now:
A = MAG 135/7, B = MAG 135/71, C = MAG 135/7 SO17, D = MAG 135/71 SO17, E = MAG
135/7 TTB, F = MAG 135/71 TTB
I like to have it as:
A = MAG 135/7, B = MAG 135/71, C = MAG 135/7 SO17, D = MAG 135/71 SO17,
E = MAG 135/7 TTB, F = MAG 135/71 TTB
This means that the part which I want to keep together is: E = MAG 135/7 TTB,
Is there a way to solve it.

Hello Ian and Abhilash,
I tried both your solutions but in both cases I get an error.
In Abhilash case I still get the Boolean error
In Ian's case I get the next error:
In this matrix there should be a subscript. Like: matrix 
I changed the code put behind data.
But I get a Boolean error.
WhilePrintingRecords;
stringvar array data;
numbervar i:=1;
stringvar data_disp;
data := split({OITM.U_Ketel_verw},",");
while i <= ubound(data) do
if i mod 2 = 0 then
data_disp := data_disp + data + "," + chr(13)
else
data_disp := data_disp + data + ",";
i:=i+1;
data_disp;
Hopefully you both have another idea what need to be changed.
Thanks,
Tim

Make datafield in datagrid a hyperlink to website

I makes an HTTPService request which returns data to a datagrid. One of the returned fields is a website (without the "http://www" and ".com" so basically just the guts ("mywebsite"). I want to make the datafield an active link but do not know where or how to do this.

You can Use A Renderer For that and can use Link Buttton as a component.

Datafield includes parent node

I am confused. I have a datagrid like always. The
dataprovider is my xmllistcollection, I have done this many times.
the datagridcolumn in question is <mx:DataGridColumn
dataField="Botanical_Name"/>
The data in the xml is:
<Botanical_Name>
Dianthus 'Bath's Pink'
</Botanical_Name>
And that's exactly what I get in the field -- including the
surrounding <Botanical_Name> tags. I want what's IN those
tags, as usual not the tags. I
cannot change the XML it is coming from a source, I must
deal with it as is.
What am I missing?

It's not so simple. Yes, that is a child node. The XML
document I am working with is actually an RSS feed. There is a lot
of information in there, a lot of it I do not need. My original
application was designed to be used with a more customized XML
feed, and it worked fine. The client changed it on me to this
insane RSS formatting.
I have temporarily pulled the tile list I was using (with a
custom renderer) in order to more easily debug this data. I am
currently working with the code below. Clicking an item in the grid
should populate the fields above it with the appropriate data
items. Where would I put a function to get the actual text? The
datagrid is less important than the text field above.
<mx:VBox>
<mx:HBox>
<mx:Image id="largeImage" />
<mx:VBox>
<mx:Text id="plantName"
text="{tl.selectedItem.Botanical_Name}"/>
<mx:Text id="plantPhonetic" />
<mx:TextArea id="plantDetails"
text="{tl.selectedItem.Description}" />
<mx:LinkButton id="plantLink" label="READ MORE"
click="goPlant(event)" />
</mx:VBox>
</mx:HBox>
<mx:DataGrid id="tl" dataProvider="{coll}">
<mx:columns>
<mx:DataGridColumn dataField="Botanical_Name"/>
<mx:DataGridColumn dataField="Description"/>
<mx:DataGridColumn
dataField="Phonetic_Transcription"/>
</mx:columns>
</mx:DataGrid>
</mx:VBox>

Accessing nested child in model to populate datafield in datagrid.

I am using Rails + Flex and I have problems to access nested
xml in a datagrid.datafield.
I reproduce this in a simple mxml sample:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" width="954">
<mx:Model id="md">
<root>
<e1>el1</e1>
<e2>el2</e2>
<child>
<c1>c1</c1>
<c2>c2</c2>
</child>
<e3>el3</e3>
</root>
</mx:Model>
<mx:DataGrid id="myGrid"
dataProvider="{md}" >
<mx:columns>
<mx:DataGridColumn dataField="e1"/>
<mx:DataGridColumn dataField="e2"/>
<mx:DataGridColumn dataField="child"/>
<mx:DataGridColumn dataField="child.c1"/>
<mx:DataGridColumn dataField="e3"/>
</mx:columns>
</mx:DataGrid>
</mx:Application>
Basically, at runtime the content of 3rd column is object
(alright) and the 4th column is empty whereas it should be "c1".
Am I doing something obviously wrong ?
Thanks for any help.

Avoiding N/A in numeric datafield : solution

Hello,
I finally found the solution to my 'N/A' problem in Forte Documentation.
As with Excel, you can provide more than one template dependind on the
numeric value :
Here is the text :
The Template value can contain as many as four formatting templates,
separated by semicolons:
the first template applies to positive NumericData object values
the second template applies to negative NumericData values
the third template applies to zero values
the fourth template applies only to NULL NumericData object values.
So if you use a template like
0;-0;0;MyText
the string MyText will appear in place of N/A.
If you want an empty string, just put one more ; in place of myText
Eric Decossaux
Cliniques Universitaires St Luc

I have managed to avoid the dreaded "N/A" for null values by fully
defining a template for the field in question. For example, a currency
field would use:
$#,##0.00;$#,##0.00;$#,##0.00;;
In order, these four templates are defined for positive values,
negative values, zero values, and null values. Defining the null
template as ";;" avoids the "N/A".
I have not however tried this with domain fields. This also does not
check for maximum values.

Using Nested Object Properties as DataGrid dataField

I am populating a DataGrid with an ArrayCollection of
Objects. Each of those Objects has a property that is itself an
Object. I want to use a property of the second (or "nested") Object
as a dataField for one of my columns.
Any idea how to make this work? Would a custom item render be
the only way?

Using the labelFunction property of the DataGridColumn would
be enough:
<mx:DataGrid width="100%" height="100%"
dataProvider="{myAC}">
<mx:columns>
<mx:DataGridColumn dataField="myProperty1" />
<mx:DataGridColumn dataField="myProperty2" />
<mx:DataGridColumn
labelFunction="myOwnLabel" />
</mx:columns>
</mx:DataGrid>
function myOwnLabel(item:Object,
column:DataGridColumn):String
return item.myProperty;
The function must have that signature in order to work, where
item is an instance of the objects in your dataProvider and column
is the DataGridColumn calling the function.

Hello Gfinistr
From what I understand to be the case you would like to use an application like VeraMail on the Treo to access your email instead of using Blazer (web browser), correct?
Here are some things to consider:
1) Since your email account is set up through MSN/Hotmail (same thing technically) unfortunately the Palm Software VersaMail or even Chattermail which has enhanced features does not support MSN/Hotmail. The only devices that support this email client are the Windows Mobile Based Devices such as Treo 700w/wx, 800w and Treo Pro.
2) Verizon's WirelessSync is a service offered by Verzion and basically you can set up an email account that will push directly to the verzion servers to access email and other information. https://www.wirelesssync.vzw.com/genweb/html/ext/Login.do?prefix=&page=/loginRedirect.do

DataField and DataBase record

We have the following problem:
when using a DataField mapped on a field of a database table,
if the value of the table field is NIL, the content of the DataField is N/A.
Is it possible to set it to an empty string instead of N/A without controlling
explicitly every single DataField and every record in the database table?
Thanks

Complex E4X query dataFields for DataGrid

Hi all, still fighting with DataGrids. For today, lets assume
I have some XML like this:
var testData : XML =
<categories>
<category name="Category 1" id="1">
<item year="2007">300</item><item
year="2008">400</item><item
year="2009">500</item>
</category>
<category name="Category 2" id="2">
<item year="2007">600</item><item
year="2008">500</item><item
year="2009">300</item>
</category>
</categories>;
And later, I define my DataGrid:
<mx:DataGrid id="test" editable="true" height="100%"
width="100%" dataProvider="{testData.category}" textAlign="center"
alternatingItemColors="[#FFFFFF,#EAEAEA]" draggableColumns="false"
>
<mx:columns>
<mx:DataGridColumn headerText="Category"
dataField="@name" />
<mx:DataGridColumn headerText="2007"
dataField="item.(@year==2007)" />
</mx:columns>
</mx:DataGrid>
I eventually want to define the columns dynamically, which I
can do. But first, I need to figure out how to populate the
columns. Why doesn't this E4X item.(@year==2007) query work
properly? I can do Alert.show( testData.category.item.(@year==2007)
) in a script portion of the mxml, and it returns the fields that
are expected.
Thanks,
Justin

dataField does not support expressions.
For nested xml data, you need to use a labelFunction. I have
an example on www.cflex.net.
