Trim value in ADF expression builder

Hi,
Can somebody tell me how can I trim a String using the expression builder from oracle ADF?
My expression is #{row.bindings.Days.inputValue eq 'W' ? viewcontrollerBundle.WORKING_DAYS : viewcontrollerBundle.ALL_WEEK_DAYS} and I want to trim row.bindings.Days.inputValue.
Sorry if the question is too easy but I didn't find something appropriate.
Thank you.

Hi,
You can do it using JSTL function trim(), [URL http://blogs.oracle.com/adf/2011/04/string_manipulation_functions_inside_el.html]This blog has explanation for using JSTL substring function in EL, you can use trim() in the same way.
Sample code:
#{fn:trim(row.bindings.Days.inputValue) eq 'W' ? viewcontrollerBundle.WORKING_DAYS : viewcontrollerBundle.ALL_WEEK_DAYS}Sireesha

Adf expression builder substring function

Hello,
I'm new to adf and I want to make substring using expression builder. I've tried #{fn:substr(bindings.getSysdate.result,1,5)} but doesn't work and I didn't find on the net.
Please help.
Thank you

Hi,
the JSTL function is called fn:substring and - as Timo mentions - you need to add
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
to the jsp:root tag of the JSPX page
This here then worked for me:
#{fn:substring(bindings.employeeName.inputValue,1,3)}

Issue with Expression Builder Popup on UI

In one of our UI's we have column which has an expression and an image as the value.One clicking the image an expression builder popup opens,where we can change the expression value(which will later gets updated in the column).This is how the column looks:
<af:column sortProperty="Condition" filterable="true" sortable="true" filterFeatures="caseInsensitive"
headerText="#{bindings.OrchestrationProcessStatusLogic1.hints.ConditionDisplay.label}"
width="400" id="column3" showRequired="true">
<af:panelGroupLayout id="pgl1" layout="horizontal">
<af:outputText value="#{row.bindings.ConditionDisplay.inputValue}"
id="outputText5" partialTriggers="eb1"/>
<af:spacer width="10" height="10" id="s1"/>
<eb:expBuilder expBuilderBean="#{dooStatusExpBuilderBean.expBuilderBean}"
tabModels="#{dooStatusExpBuilderBean.tabModels}"
id="eb1"
expBuilderListener="#{dooStatusExpBuilderBean}"
expValue="#{row.bindings.ConditionDisplay.inputValue}"
rendered="#{!pageFlowScope.releasedProcess}"/>
</af:panelGroupLayout>
</af:column>
When we enter an expression in the popup and click OK,we are implementing a certain method(processValueChange(ExpBuilderEvent evt) from oracle.bpel.expbuilderdc.model.ExpBuilderListener) in dooStatusExpBuilderBean to check the correctness of the expression.
When we enter an incorrect value in the Expression builder pop up and click 'OK',An error message is displayed and Expression Builder popup closes and the old value of expression is retained in the column.Is this the default behaviour? Wouldn't it be more practical if the expression builder popup remains open in case we enter incorrect expression and click OK.
We don't have the handle over expression builder pop up ,Is there a way we can override the default behavior and keep the pop up in case of an invalid expression and errors?
Any inputs on this would be really helpful.
Thanks,
Sowjanya.

Jdev 10g, ADF- expression based on column value

Hi,
I have an ADF table with a column in it that is populated through a data control. The column can be one of five values (1 - 5) which mean different statuses (Approved, Denied, Pending, etc). I was just wondering if anyone could recommend a way to do the translation in the table column.
I was looking at the expression builder but it didn't seem like it would take more than the #{row.Status==1 ? 'Approved': 'Others'} and I have 5 different statuses that I'd like displayed to the user.
Thanks

Hi,
yes you can nest conditions like here:
inlineStyle="#{row.Status == '1' and row.ErrStatus == '0' ? 'color:rgb(0,255,0);' : row.Status == '2' and row.ErrStatus == '0' ? 'color:rgb(210,170,0);' : row.ErrStatus == '1' or row.ErrStatus == '5' ? 'color:rgb(0,0,255);' : row.ErrStatus == '3' ? 'color:rgb(255,0,255);' : row.ErrStatus == '4' or row.ErrStatus == '9' ? 'color:rgb(255,0,0);' : row.ErrStatus == '2' ? 'color:rgb(205,0,0);' : ''}
{code}

Why is ADF Bindings node not displayed in Expression Builder window?

Hello,
I'm using Oracle JDeveloper Studio Edition Version 11.1.1.1.0, and I've created a Fusion Web Application and I've configured ADF Authentication and Security for my web project, using the provided wizard.
On a certain page, I've placed a Go Link component, and I'm trying to edit the Text and Destination Property using EL Expressions. When I open the Expression Builder window all I can see are the following nodes: ADF Controller Objects, ADF Managed Beans, JSF Managed Beans and JSP Objects, but no ADF Bindings. I need to access the securityContext properties, and from what I've read in B31974-03, I need ADF Bindings.
Also, I've tryied using the search field from the Expression Builder windows, without any luck.
This is probably a newbie problem, but I really can't figure it out. Please help.
Bogdan.

Hi,
maybe your problem is that you don't have created pageDef related with your page. Try right click on your page and Go To Page Definition. It will create the related pageDef if it does not exist.
Hope this helps

Ceiling Function in Expression Builder in an Update Field Value Workflow

I'm trying to use the "ceiling" function in an update value workflow. I want to multiple the number value in field A by the currency value in field B and have that new value display in field C. But I also want to round up or ceiling the resulting value to the nearest $0.10. Here is what I want to do, but this is not working. PLEASE HELP.
EXPRESSION BUILDER FUNCTION
FIELD C = CEILING((FIELDA*FIELDB)+FIELDB,0.1)
Edited by: gprobertson on Feb 15, 2010 10:20 AM

Hi, I dont think this function is supported in workflow expressions. It is only available in reporting / analytics. Even there it only Rounds a noninteger numerical expression to the next highest integer. Even the function round doesnt seem to be available in workflow functions list

Expression Builder: convert string to number

Hi all,
I'm having trouble building a field validation rule for bank account numbers.
The numbers have 12 positions, so I cannot use a string or text number.
The validation rule to be implemented is that the last two digits are calculated based on the first 10 (modulo 97).
However, when I use the Mid function to pick the first characters, I am unable to do any calculations on it. Apparently, the string to number conversion doesn't work (it should work when I read the manual, as it says that when using an operator between two data types, the second type is converted to the first (cf. example of 1234+abcd (should result in 1234 as to the manual))). So I tried '1*Mid(...)' or '0+Mid(...)'. Syntactically the expression builder accepts it and I can save it. BUT when I change the particular value on the screen, it gives me an SSO error (not the Field Validation error message I entered).
Why isn't there simply a function ToNumber (like ToChar)????? How could I workaround this?
Any input very welcome!
Frederik

Apparently, I was a bit confused when typing the first sentence, it should be:
The numbers have 12 positions, so I cannot use an integer or number data type, but have to use String.

How to get the logged in userId value in adf task flow OIM11g R2

3 different ways to retrieve the username (not sure what you mean by user ID) :

Also provide your JDev version.
Basicly, you should use the groovy expression in a view criteria (it's the fastest and easiest way) and call that view criteria whenever you need it.
That's if you are using ADF BC of course.

Checking for empty tags using expression builder for XPATH

I am creating several filters in a mediator for several parallel paths. I am trying to route the mediator to the correct DB adapter based on what tags are empty in the incoming XML. The XML has 1 required tag and 3 optional. So for the expression, I am using the expression builder to load the tag name then putting either [text()] or [not(text())] immediately after each tag with an "and" in between for the 3 optional elements. The problem I am having is they always return false. For example, if I enter a value for an optional tag and put [text()] after it, it evaluates to false. What is the correct way to check if an element has text or not?
Thanks in advance!

Hi,
Its not recognizing the getVariableData func... instead try this:
string-length(xpath)>0
ex: string-length($in.body/imp1:manoj/imp1:C1)>0
It works... Happy deploying ... :)

Compare only DATE portion of a datetime field in Expression builder

Hi! All,
This may be a simple question, but I couldn't find the answer. I have a query where I want to say :
Expression exp = exp1.get("startDateTime").equal(pDate);
here pDate is a java.util.Date class with a time stamp.
I wish to basically compare just the DATE portion of the value stored in the data base with only the DATE portion of "pDate" and ignore the time component.
How do I do this in expression builder?
By the way we are on Toplink 9.0.4.5
Thanks

There are a couple of ways to accomplish this. You could use between(beginningOfDay,endOfDay) where beginning of day is 12:00:00am on the date specified in pDate and end of day is 11:59:59pm on pDate. Or you could consider using a combination of dateName(), datePart(), and/or truncateDate() expressions to compare at the day, month, year level. I am not sure which would give you better performance, so you might need to do some testing to verify.
In the first case, create beginningOfDay and endOfDay based upon the date housed in pDate. Then:
Expression selectionCriteria = exp1.get("startDateTime").between(beginningOfDay,endOfDay);
In the second case, there would be a little more code to write:
Expression startDateTimeExp = exp1.get("startDateTime");
Expression dayExp = startDateTimeExp.datePart("day");
Expression monthExp = startDateTimeExp.datePart("month");
Expression yearExp = startDateTimeExp.datePart("year");
int desiredDay = get day of month from pDate;
int desiredMonth = get month of year from pDate;
int desiredYear = get year from pDate;
Expression selectionCriteria = dayExp.equal(desiredDay).and(monthExp.equal(desiredMonth)).and(yearExp.equal(desiredYear));
Check out the TopLink API docs on the Expression class for more details on what these Expression building methods do : http://download-west.oracle.com/docs/cd/B10464_05/web.904/b10491/index.html

How to user #{or} in expression builder

Dear All,
am using jdeveloper 11.1.1.3
I have an input text in an adf page , I need to disable this input text depending on two bindings with or operator--> if one of them is true then disable the input text...
If this possible and if yes then how ?
I noticed the Operands in the expression builder popup but i dont know how to use it
Regards,
Lama
Edited by: Delta on Sep 6, 2010 1:35 AM

You can use 'and' and 'or' instead of '&&' and '||', which is especially nice for '&&' as you would have to use '& amp ;& amp ;' (without spaces) if typed into source of the jspx directly.

Object type mappings in expression builder

Hi,
I'm trying to use expression builder to give me a query returning all instances of an object with a particular foreign key, and where 'active' = true.
'active' is a CHAR field in the database with values 'T' or 'F' and this is mapped to a Boolean in workbench as true and false.
All works fine in normal operations, retrieving and writing the data.
I've written the expression as
myId EQUAL arg
AND
active EQUAL 'true'
where 'true' is a literal of type Boolean.
Unfortunately, running this query generates an error that no mapping exists for 'true'.
I've also tried changing it to
active EQUAL 'T'
where 'T' is a literal of type String.
This also generates an error.
It seems to me as though the object type mapping is confusing the expression builder and it can't generate the sql correctly.
Any ideas?

Can you post the specific version of TopLink, the exact code you are using to construct and execute your query, as well as the error message with stack trace. With these items we should be able to provide an answer for you.

Using managed bean method in expression builder

Hello,
I'm new to adf and I have the following problem.
I have a managed bean in session scope that has the following method:
public boolean alertMessages() throws NamingException,
SQLException {
if (condition)
{ return true;}
else
{return false;}
I have a page that has a link. Using the expression builder and according the function result I want to make the link bold or not.
I use the expression #{sessionScope.backing_pages_index.alertMessages ?'bold':'normal'} but it does'n work.
Could anybody help me.
Thank you,

Hi..
If you add your bean as sessionScope No need to add sessionScope to EL front,and should setter and getter for alertMessages
use *font-weight:#{backing_pages_index.alertMessages ? 'bold':'normal'}*
try as follows it is working for me
> private boolean alertMessages;
> public void setAlertMessages(boolean alertMessages) {
> this.alertMessages = alertMessages;
> }
> public boolean isAlertMessages() {
> if (true) {
> return true;
> } else {
> return false;
> }
> }
<af:commandLink text="commandLink 1" id="cl1" action="CustomPage"> inlineStyle="font-weight:#{backing_pages_index.alertMessages ? 'bold':'normal'};"/>

How to do substring with Expression Builder

Hi,
I only execute a substring with Expression Builder, this is possible?
thanx

Hi!
With Expression Builder it is not possible as the EL by default does not have such function.
But you may:
1. Use JSTL 1.2 functions like "${fn:trim(' MYSTRING '}"
2. Write your own function and TagLib - see on net
Also, you may write a custom Map implementation and expose it in some backing bean to make it available in EL without need to create TagLib (as #{mybean.trim[' some string ']"). But this way is much complex if you need more than singe parameter for your function...
