Using the attribute "TruncateAt"

Hi,
so as many readers or posters i´m new to JDeveloper. Now i have a problem. It looks like there´s no 'TruncateAt' attribute for the af:goLink. With af:outputText he´s doing well. So are there any possibility's to cut an URL which is shown in a column? Thx for suggestions.
Dirk

Normally, Roel's advice is good. However, if you DO want DDT to use existing attributes as your foreign key columns, you can do it. Make sure that your primary key attributes are noted as such. I believe that the column name of the foreign key in the detail table does need to be the same as the column name of the primary key in the master table.
In DDT, press the Settings button and select the tab labeled "Keys". Uncheck the checkbox labeled "Create surrogate keys for all new tables". Of course, if you have some tables for which you DO want DDT to create key columns, you'll have to generate these in a separate DDT batch. You can always see exactly what DDT proposes to create by pressing the "Show Run Set" button.

How can I customize the toolbar when using the attribute browser

In CVI 2012, the toolbar changes depending on the environment, e.g. it is different for the source window and the UI editor. The toolbar can be customized using the menu Options / Toolbar...
Unfortunately, when using the attribute browser of the UI editor, another toolbar is displayed, i.e. not the UI editor toolbar.... I would have assumed that the attribute browser belongs to the UI editor, obviously it doesn't... So how can I customize the toolbar when using the attribute browser?
Solved!
Go to Solution.

Luis,
It's nice to have you back
Thank you for the clarification, so I'll elaborate a bit more: In the regular workspace toolbar, I have a disk symbol to save the file. This symbol is gone in the attribute browser...
So I have three different toolbars, for source code (workspace), UI editor, and the UI editor displayed but the attribute browser clicked on (selected)...
Thanks

Select the printer tray using the Java Print Service with JDK 1.4.2

Hello,
I have got a problem with 1.4 Printing. I would like to specify the printer tray for printing on Windows platform (XP and NT4.0). I am trying to use the attribute javax.print.attribute.standard.MediaTray class (ex. MediaTray.BOTTOM).
Howerver, I can control the printer tray if I use the PCL driver of the printer. If I user the postscript driver I am not able to control the printer tray. I can reproduce the problem with 3 different printers (HP, Lexmark and Nashuatec).
I used the getSupportedAttributeValues to check the supported values of the Media
Media med[] = (Media[])service.getSupportedAttributeValues(Media.class, null, null);
for (int k=0; k<med.length; k++) {
System.out.println("Name : " + med[k].getClass() + " - Value : " + med[k].getValue());
With the PCL driver I have the following output and I can control the printer tray.
Name : class javax.print.attribute.standard.MediaTray - Value : 0
Name : class javax.print.attribute.standard.MediaTray - Value : 2
Name : class javax.print.attribute.standard.MediaTray - Value : 4
Name : class sun.print.Win32MediaTray - Value : 0
Name : class sun.print.Win32MediaTray - Value : 1
With the postscript driver I have the following output and I cannot control the printer tray
Name : class sun.print.Win32MediaTray - Value : 5
Name : class sun.print.Win32MediaTray - Value : 6
Name : class sun.print.Win32MediaTray - Value : 7
Name : class sun.print.Win32MediaTray - Value : 8
Name : class sun.print.Win32MediaTray - Value : 9
As I must use the postscript printer, can someone help me?
Thanks.

Hello,
Can you tell me how it's possible to selet the tray using the PCL?
I print on the following way:
PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null);
AttributeSet aset = new HashAttributeSet();
aset.add(new PrinterName("\\\\107208\\SBE08111", null)); // select printer
......Now I tried to add your code and I get the following output:
0: Name : class javax.print.attribute.standard.MediaSizeName - Value : 40
1: Name : class javax.print.attribute.standard.MediaSizeName - Value : 41
2: Name : class javax.print.attribute.standard.MediaSizeName - Value : 45
3: Name : class javax.print.attribute.standard.MediaSizeName - Value : 42
4: Name : class javax.print.attribute.standard.MediaSizeName - Value : 4
5: Name : class javax.print.attribute.standard.MediaSizeName - Value : 5
6: Name : class javax.print.attribute.standard.MediaSizeName - Value : 27
7: Name : class javax.print.attribute.standard.MediaSizeName - Value : 46
8: Name : class javax.print.attribute.standard.MediaSizeName - Value : 59
9: Name : class javax.print.attribute.standard.MediaSizeName - Value : 60
10: Name : class javax.print.attribute.standard.MediaSizeName - Value : 55
11: Name : class javax.print.attribute.standard.MediaSizeName - Value : 38
12: Name : class javax.print.attribute.standard.MediaSizeName - Value : 16
13: Name : class javax.print.attribute.standard.MediaSizeName - Value : 57
14: Name : class javax.print.attribute.standard.MediaTray - Value : 0
15: Name : class javax.print.attribute.standard.MediaTray - Value : 2
16: Name : class javax.print.attribute.standard.MediaTray - Value : 1
17: Name : class javax.print.attribute.standard.MediaTray - Value : 6
18: Name : class javax.print.attribute.standard.MediaTray - Value : 4
19: Name : class sun.print.Win32MediaTray - Value : 0
20: Name : class sun.print.Win32MediaTray - Value : 1
It's a printer with to trays, so I suppose the last two lines are important, but I'm not possible to effectively select the tray I want to print..

How to get the attribute values out?

Hi everyone,
<root>
<category name="Mens Clothing" id="0">
<subcategory>Active/Baselayer Tops</subcategory>
<subcategory>Active/Baselayer
Bottoms</subcategory>
</category>
<category name="Womens Clothing" id="1">
<subcategory>aaa</subcategory>
<subcategory>bbb</subcategory>

</root>
How to get the attribute values out? For example "Mens

"Active/Baselayer Bottoms"
var myXml:XML = new XML(event.result);

Here is attribute identifier operator from FB Help:
@ attribute identifier Operator
Usage myXML.@attributeName
Identifies attributes of an XML or XMLList object. For
example, myXML.@id identifies attributes named id for the myXML XML
object. You can also use the following syntax to access attributes:
myXML.attribute("id"), myXML["@id"], and myXML.@["id"]. The syntax
myXML.@id is recommended. To return an XMLList object of all
attribute names, use @*. To return an attribute with a name that
matches an ActionScript reserved word, use the attribute() method
instead of the @ operator.
Operands attributeName:* — The name of the attribute.
Example
How to use examples
The first example shows how to use the @ (at sign) operator
to identify an attribute of an element:
var myXML:XML =
<item id = "42">
<catalogName>Presta tube</catalogName>
<price>3.99</price>
</item>;
trace(myXML.@id); // 42The next example returns all attribute
names:
var xml:XML =<example id='123' color='blue'/>
var xml2:XMLList = xml.@*;
trace(xml2 is XMLList); // true
trace(xml2.length()); // 2
for (var i:int = 0; i < xml2.length(); i++)
trace(typeof(xml2
)); // xml
trace(xml2.nodeKind()); // attribute
trace(xml2
.name()); // id and color
} The next example returns an attribute with a name that
matches a reserved word in ActionScript. You cannot use the syntax
xml.@class (since class is a reserved word in ActionScript). You
need to use the syntax xml.attribute("class"):
var xml:XML = <example class='123'/>
trace(xml.attribute("class"));

How do I use the ? operator in JSF tag attributes?

I want to do something like this:
<h:inputText styleClass="${myBean.valid ? 'styleA' : styleB'}" ...>
What do I have to do to use this Expression language?
With the #{...} expression the ? operator doesnt seem to be available.
When I use the ${...} expression I am getting this error:
javax.servlet.ServletException: ServletException in '/WEB-INF/body/Test.jsp': /WEB-INF/body/Test.jsp(12,5) According to TLD or attribute directive in tag file, attribute styleClass does not accept any expressions
javax.faces.webapp.FacesServlet.service(FacesServlet.java:121)
Can anybody please help?
Thanks!

Personally, i'd do:
<h:inputText styleClass="styleA" rendered="#{myBean.valid}"/>
<h:inputText styleClass="styleB" rendered="#{!myBean.valid}"/>

How do I use the same css style but different attributes, Without affecting another page.

Hey everyone,
I am using the "NivoSlider", for my dreamweaver page but I am not sure how to tell styles that one page has one attribute and the other one will have a different attribute.
For example: in my "about us" I have a small slideshow with its own pictures. I then put a gallery page with its own pictures, yet, I want to make that slideshow box larger without affecting the other small slideshow.
I am using just one Style.CSS for the slideshow.
Anyways, is their a way to tell tell the code that one page is going to be a different width then the other?
Thank you!

Embedded CSS rules take priority over styles in external style sheets. So you can add page specific rules between your document's <head> tags and after all other links to external CSS files.
<style>

What my program do is to get the encoding of XML files and convert them to UTF-8 encoding files, while I need this "encoding" information of the original XML document thus I can convert...
After reading specifications and JDOM docs, the truth turns to be disappointed, no function is provided to get this information in JDOM level 2(the current released one), while it's promissed that this function will be provided in JDOM level API....
Thanx all for your help and attention!!!

If you are deploying from Visual Studio then please follow this post:

How can i add custom attributes to a new Class Object using the API ?

Hello everyone,
Here is my problem. I just created a subclass of Document using the API (not XML), by creating a ClassObjectDefinition and a ClassObject. Here is the code :
// doc is an instance of Document
ClassObject co = doc.getClassObject();
ClassObjectDefinition cod = new ClassObjectDefinition(ifsSession);
cod.setSuperclass(co);
cod.setSuperclassName(co.getName());
cod.setName("MYDocument");
ClassObject c = (ClassObject)ifsSession.createSchemaObject(cod);
Everything seems to be OK since i can see the new class when i use ifsmgr. But my question is : how can i add custom attributes to this new class ? Here is what i tried :
AttributeDefinition value = new AttributeDefinition(ifsSession);
value.setAttribute("FOO", AttributeValue.newAttributeValue("bar"));
c.addAttribute(value);
But i got the following error message :
oracle.ifs.common.IfsException: IFS-30002: Unable to create new LibraryObject
java.sql.SQLException: ORA-01400: impossible d'insirer NULL dans ("IFSSYS"."ODM_ATTRIBUTE"."DATATYPE")
oracle.ifs.server.S_LibraryObjectData oracle.ifs.beans.LibrarySession.DMNewSchemaObject(oracle.ifs.server.S_LibraryObjectDefinition)
oracle.ifs.beans.SchemaObject oracle.ifs.beans.LibrarySession.NewSchemaObject(oracle.ifs.beans.SchemaObjectDefinition)
oracle.ifs.beans.SchemaObject oracle.ifs.beans.LibrarySession.createSchemaObject(oracle.ifs.beans.SchemaObjectDefinition)
void fr.sword.ifs.GestionDocument.IFSDocument.createDocument(java.lang.String)
void fr.sword.ifs.GestionDocument.IFSDocument.main(java.lang.String[])
So, what am i doing wrong ?
More generally, are we restricted in the types of the attributes ? (for example, would it be possible to add an attribute that would be an inputStream ? Or an object that i have already created ?).
Any help would be appreciated. Thanks in advance.

Hi Guillaume,
you're welcome. Don't know exactly, but assume that ATTRIBUTEDATATYPE_UNKNOWN
is used to check for erronous cases only
and it shouldn't be used otherwise.
Creating your own objects could be simply done via
ClassObject ifsClassObject;
DocumentDefinition ifsDocDef = new DocumentDefinition(ifsSession);
// get class object for my very own document
ifsClassObject = ClassObject.getClassObjectFromLabel(ifsSession, "MYDOCUMENT");
// set the class for the document i'd like to create
ifsDocDef.setClassObject(ifsClassObject);
// set attributes and content for the document...
ifsDocDef.setAttribute("MYFOO_ATTRIBUTE",....);
ifsDocDef.setContent("This is the content of my document");
// create the document...
PublicObject doc = ifsSession.createPublicObject(ifsDocDef);
null

How to get cm:search to use the max attribute when creating the SQL query?

When we use the max attribute in the cm:search tag, it does not seem to honor the max attribute when creating the SQL query. However, the result returned from the tag is limited to the number specified by the max attribute. Then the tag seems to work as intended, but the performance will be sub optimal when the SQL query returns unnecessary rows to the application.
We use the cm:search tag to list the latest news (ordered by date), and with the current implementation we have to expect a decrease in performance over time as more news is published. But we can’t live with that. We need to do the constraint in the SQL query, not in the application.
The sortBy attribute of cm:search is translated to “order by” in the SQL query, as expected.
Is it possible to get cm:search to generate the SQL query with an addition of “where rownum <= maxRows”?

Hi Erik,
The behavior of a repository in regards to the search tag's max results parameter is dependent on the underlying repository's implementation. That said, the OOTB repository in WLP does augment the generated SQL to limit the number of rows returned from the database. This is done in the parsing logic. This behavior may differ with other repository implementations.

Using the value "Image/*" for the accept attribute of the HTML input Element, how can I add .pdf to the array of preconfigured file types (.jpe, .jpg, .jpeg, .?

On a form, using the value "image/*" for the accept attribute of the HTML input Element, how can I add .pdf to the array of pre-configured file types (.jpe, .jpg, .jpeg, .gif, .png, .bmp, .ico, .svg, .svgz, .tif, .tiff, .ai, .drw, .pct, .psp, .xcf, .psd, .raw)?
Say I wanted to add .gif, .jfif or .ico. I find this array limited, how can I add types to image?
<input type="file" name="file" accept="image/*" id="file" />
mimeTypes.rdf does not seem to allow this.

''mimeTypes.rdf'' has nothing to do with web development. It's a file that stores your file handling preferences (e.g. if you want ZIP files automatically saved or opened).
You can't change the file types of the pre-defined content specifiers (audio/*, video/*, image/*), but you can specify additional MIME types. To add PDF to your above example,
<pre><nowiki><input type="file" name="file" accept="image/*,application/pdf" id="file" /></nowiki></pre>
For details, see

Populating CRM marketing attributes using the APD

Hi Experts
We are having problems with populating CRM marketing attributes using the APD. When we run our process we get the error message:
CRMBW_ATTR_WRITE005: Error when processing function module CRMBW_UPDATE_BPMKT_5. Message no. RSAN_MDL024
As you can see, we are using the new function module CRMBW_UPDATE_BPMKT_5 since the old CRMBW_UPDATE_BPMKT did not work either.
Do we have to add a reference to a infoobject in transaction CRMBWTARGETS? We have not done this because the marketing attribute in CRM doesnt have decimals and all the objects in BI have. Could this be the cause of the error?
Kind regards
Erik

Hi Ramesh,
Thanks for quick reply.
I have already followed the procedure you have described. Since there is not common objects between ODS and Bpatner infoobject, i am not able to do mapping.
for eg. my ZBPARTNER infoobject has attributes like zfooty, ztennis and zrugby but my ODS has char name , char value, counter for multiple values infoobjects.
I am following the example in the demo content to work out the process but could not understand how the data is getting uploaded from ODS to Business partner.
