Using process variables in XPath

I am trying to use a variable (/process_data/@Division) to identify an xml node to determine the person for a task:
/process_data/DivisionRolesXML/divisions/division[Division='string(/process_data/@Division )' and Position='Div Executive']/LDAPId
I get no value returned (e.g. result is 'null'). The log shows that @Division has a string value.
It works if the actual value (not variable) is specified:
/process_data/DivisionRolesXML/divisions/division[Division='division_name' and Position='Div Executive']/LDAPId
Thoughts anyone ?

Hi
I'm reasonably sure that you need to remove the single quotes in your expression. The single quotes mean that your entire sub-clause is being treated as a string, rather than as an expression.
i.e.
...[Division='string(/process_data/@Division)' ...
change to
...[Division=string(/process_data/@Division) ...

Using process variables in conditional transition

HI,
I am usin Oracle BPM 1.03
I wanto to have a value of a variable visible in the user's inbox. Therefore, I need to use project level variables.
I also want to use this variable in conditional tranistion, but the condition editor only allows Instance level variables.
Am I overlooking something? Is there an easy way to use project variable in conditional transtions?
Matej

you should be able to manually type the transition condition on the properties tab.
xArea == "MyArea"
where xArea is a Project Variable

Using process variables in subprocesses

Hi all,
I have a large process which I would like to decompose into smaller sub processes (e.g. a process that renders a pdf and sends it to a user) which I then can invoke in a orchestration of all the small workflows. I hope you understand what I am trying to say.
I have set some input and output variables for the subprocess, but in the Workbench no fields for these names appear. I guess this is the way to provide the subprocess with input and output values but I need to do some more setup of the variables I guess however I am not sure what to do.
Sincerely
Kim Christensen

Nith is correct. Here are some links to documentation (it's the ES2 docs, but it mostly applies to ES as well):

Using the variable placeholder ? in an XPath expression

Is this a supportable feature or am I doing something wrong?
I didn't see any examples in the Oracle XML DB Developers Guide where there was a ? in an XPath expression.
I also tried "?" with the same issue...

I incorporated this suggestion and it worked very well. Thanks!
Now I have converted my solution to use a structured index. As such, I want to write the where clauses in terms of column names rather than XPath expressions.
I hoped it was as simple as changing the code that generates the XPath expression to generate a SQL expression. After making that change, I'm now getting this error:

The static SQL is:

             AND ?
      ) ORDER BY CREATED_TIME desc
    ) WHERE rn > ? and rn <= ?So I'm thinking that Oracle must perform strong checking in SQL, not allowing the '=' operator to be substituted. If I run this query in Toad, replacing the ? with the SQL, it runs fine...
Can someone tell me whether or not this is a legal substitution?
The SQL that runs in Toad is:

Creating variables in Process Flows and using thse variables in the filter

Hi,
I am new to OWB and in learing stage. Need to information.
*1. as to how pass/create/use variables to OWB mapping ?*
*2. Creating variables in Process Flows and using thse variables in the filter operator of the OWB mapping?*
*3. Other mechanisms of how to create/use variables within OWB mapping itself ?*
can you please provide the above details and guide me / help me in this regard.
Thanks,
skms.

1. Add parameters to your mapping using the MAPPING INPUT PARAMETER from the pallette.
2. Add parameters to the START operator in the process flow. Bind the process flow parameter to the Mapping parameter.
3. May be appropriate to use CONSTANTS instead of parameters.
Regards
Si

How to use System Variable SY_ROW in the Process Instruction Category

Hi ,
I want to assign a value of System variable SY_ROW to a Normal Variable in the Process Instruction Category and use it in the formula. Please help me with the Syntax in the Process Instruction Category to get the System Variable: SY_ROW value into a Variable.
Thanks,
SV

Hello,
You can use these variables in formulas or, for example, to pass on certain pieces of information to a function module. How the function called by the function module behaves depends on the type of information passed on.
SY_ROW is used to view the current Table line.
Please look into the below link for more details on syntax :

Use variable in Xpath ?

Is it posible to use ?
<xsl:variable name="numPages" xdofo:ctx="incontext" select="ceiling( count(//LIST_G_1/G_1[variable:groupIterator]/LIST_G_2/G_2) div 9 )"/>

plz don't duplicate - Use variable in Xpath
<xsl:variable name="numPages" xdofo:ctx="incontext" select="ceiling( count(//LIST_G_1/G_1[variable:groupIterator]/LIST_G_2/G_2) div 9 )"/>as example
<xsl:variable name="numPages4" xdofo:ctx="incontext" select="ceiling( 5 div 2 )"/>
<xsl:variable name="numPages5" xdofo:ctx="incontext" select="ceiling( $numPages4 div 2 )"/>

Process variable string into filename at Save service

Hello,
Does anyone know how to put a string into the Pathname Pattern (Template) property of a Save service (FileUtilsService - Write Document) ?
What I'm trying to do is strip the /'s out of a date string and put that date into a filename. For example, 042208_Greg.pdf
Instead I get d:\WMS\C0419\04\22\08\_Greg.pdf
I want: d:\WMS\C0419\042208_Greg.pdf
I have a Set Value service putting a form submit date (MM/DD/YY format) into a process variable called @stringDate. I am stripping /'s out of the date and setting @stringDate like so: /process_data/@stringDate <--- concat(substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approvers/Init iator/Date,1,2),substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approv ers/Initiator/Date,4,5),substring(/process_data/xfaform/object/data/xdp/datasets/data/C041 9/Approvers/Initiator/Date,7,8))
At the Save file service, I am using @stringDate in my Pathname Pattern (Template) to create the filename: d:\WMS\C0419\{/process_data/@stringDate}_{$/process_data/xfaform/object/data/xdp/datasets /data/C0419/Approvers/Initiator/CompletedBy/Name$}.pdf
Thanks,

Hi Greg
You've done a great job getting this done with xpath.
It looks to me like you've done everything right - what's not working - are you getting an exception, or is the file being saved with the wrong name?
There is a nice little DateFormatter component here, that might make things a little easier/flexible.

Initial a process variable of PDFSignatureAppearanceOptionSpec

I got a problem in set configuration parameters for Sign Signature Field activity. In this activity, there is a field call Apprearance Option Spec. We can not set it in literal value as we want it configurable without changing the Process. So here we use variable. We create a process variable of type PDFSignatureAppearanceOptionSpec. In SetValue activity, we try to set all the fields of this variable. But the problem is most of the fields in this variable are not trivial, they have some class type, TextDirection or AppearanceType, it is hard to set the value for those fields in XPath Builder. Do you have any idea to initial a process variable that is PDFSignatureAppearanceOptionSpec type?

Hi Pietro,
As the task is associated with the WD mapped to it, we will be able to access only the WD Interface controller context associated with it and also few other Task attributes.

Include variable into xpath expression of transformation activity

Are we able to include variable from the BPEL process into the xpath expression of the transformation activity?
I tried it but I received error saying it does not recognize the function bpws:getVariableData('loopCounter') when I included it into the xpath expression inside the transformation.
Thanks.
Kenny

Maybe I am giving a bad example. Instead of bpws:getVariableData('loopCounter'), I need something like bpws:getVariableData('accountName') which is being used in the filter like /root/accounts/account[name=bpws:getVariableData('accountName')]
The assign will not work in this xpath expression because it return multiple nodes in source.

How to use one variable as a default value for another variable?

Hi Experts,
Is it possible to use one variable as a default value for another variable?
For example:
Variable 1 = current calendar year month
Variable 2 = mandatory input ready variable for calendar year month
I want to use variable 1 as default value for variable 2, but also have the ability to change the month if required.
Thanks!
Kathryn

u can use replacement path variable
in that case u can replace the values of 1 variable with the another variable...
but u cannot do this setting
u cannot make variable 2 as mandatory
u cannot enter value for variable 2
because by default it will take the value of variable 1
u have to make follow settings
variable 2
name , technical name
processing by = replacement path
infoobject = ocalmonth
next tab
replaced by another variable
variable name
offset start , offset lenght
save and hit okey

How to get value of process variable in another flex form

Hi,
currently we are using Flex 3 for form development in LiveCycle ES workspace.
We have got an "Assign Task" service operation. This service operation has got a process variable defined for "input" and "output".
The service will be called in a flex form. When the process is called a task will be sent to a user.
When the user opens this task another flex form will be opened. All these steps work fine!
How it's possible to get the value of the defined process variable from the first flex form (which starts the process)
to the flex form which will be displayed when the user opens the task?
Thanks very much for your help!
Holger

Solutions:
-The 'proper' way for application specific stuff is to use a properties file, not env vars.
-Use System.getenv(), only works for versions before 1.3
-Use the java command line option '-D'
-Use Runtime.exec(), similar to the way you suggested.
-Use JNI.

Unable to access process variable value in the DXFA file

Hi,
I am using the On-Demand-Assembly solution accelerator to stitch forms. I am trying to access a process variable inside the dxfa file.
This is the syntax i used: <c:forEach var="templateItem" items="${requestScope.paramsMap.templateList}"> The templateList value is not being fetched. The same code works fine if I hard code the items.
paramsMap is set as the Parameters Map variable in the invokeODADocument service.
Any suggestions on what I might be missing here??
Thanks.
Regards,
Vidya

Vidya Kesavan,
Just a shot in the dark here, but I think you may have a typo in "requestScropt.paramsMap.templateList" where "paramsMap" should be "paramsmap" in the context of the CSC template. That could be the cause, making it impossible for ODA to find the variable you're referencing. (I believe it's "paramsmap" within the CSC regardless of what name you have the Parameter Map process variable.)
