Transition using a boolean

Hi
In my process flow, I have a transformation which outputs parameter B_1, which is a BOOLEAN value.
I need to create 2 transitions from this transformation based upon whether B_1 is true or false.
In the Transition Condition Editor I select 'Complex Condition', but I can't find how to express "B_1 = FALSE".
It keeps coming up with with an error on validation.
Does anyone have an idea how this is done?
Many Thanks

Hi,
Simply, ignore validation error and test workflow in action. I think that this stuff must work well. Not always validation responds correct.

How to use a boolean to log time?

Hi all,
In my application, I want to use a boolean to log a time on continuous bases. When boolean gets 1, it logs system time. When boolean gets 0, it logs system time...& the cycle goes on.. We can use push button for changing boolean value...
Please guide me,,
Thank you,

How to Use a Boolean Vector To Index an Array

Say I have an array A = [1 2 3 4 5 6 7 8 9 10].
I also have a boolean array B = [1 1 0 0 0 0 0 0 0 1].
I want to use the boolean array B to pick out elements in A, creating a new array C = [1 2 10]. In MATLAB, I would just type C = A(B).
I'm scratching my head trying to figure out how to do this. One solution would be to run through a for loop, querying B(i), and deleting A(i) if B(i) = 1. But this would change the size of A, so that the second time I did this, my index would be wrong.
Anyone know a clean way of doing this?
BONUS: If I have a 2D AA, with multiple columns, it would be nice to use B to pick out multiple columns of AA (in MATLAB, this would be CC = AA(:,B).

This can be done with auto-indexing with conditional tunnels. The same approach could easily be applied to a 2D array, as well:

Use of boolean variables in BPEL switch statements

I have a workflow with a single boolean input parameter:
<element name="input" type="boolean"/>
I wish to use a switch statement within the workflow, based on the value of that boolean parameter.
When I use the following XPath expression:
bpws:getVariableData("input","payload","/tns:BooleanRequest/tns:input")
I get the correct functionality, although I get the following BPEL compiler warning:
" [bpelc] [Warning ORABPEL-10078]: return value of this expression may not be a boolean
[bpelc] [Description]: in line 35 of "C:\eclipse\workspace\Boolean\Boolean.bpel", xpath expression "bpws:getVariableData("input","payload","/tns:BooleanRequest/tns:input")" used in <switch> may not return boolean type value, the xpath engine would automatically try to convert the return value to boolean..
[bpelc] [Potential fix]: Please use one of the built-in boolean functions from xpath http://www.w3.org/TR/xpath#section-Boolean-Functions to convert the return value to boolean.."
However, the boolean functions referenced do not appear to be relevant to a variable which is already of a boolean type. If I attempt to use the boolean() function in my XPath expression, I get rid of the compiler error, but the workflow now does not work as required.
How can I get rid of the compiler warning and still get the required functionality, and/or am I doing the wrong thing?
I am currently running on JBoss, with BPEL release 2.1.2 [build #1226].
Thanks for any help or ideas.

Hi Marlon,
Thanks for that - I guess we have to accept the vagaries of XPath and the absence of type-checking for variables.
I hadn't fully understood until I started investigating that I can assign ANY string to variable of type xsd:boolean, which has been the cause of some of the confusion for me - whether that value is then considered true or false depends on how you write your test condition.
I tried with your condition, and it didn't seem to work (evaluated to true if the variable data was the string "true()", but otherwise it seemed to always evaluate to false.
I also tried the following:
condition="bpws:getVariableData('booleanVariable')=true()"
but that evaluates to true for any string of length > 0.
The only one I can get to consistently work is:
condition="bpws:getVariableData('booleanVariable')=string(true())"
although that means that variable data of "TRUE" will evaluate to false (may well be the correct behaviour, depending on how you're setting the boolean variable in the first place).

"apply transitions using" is missing in my preference dialog box!

Why do I not have the "apply transitions using" in my preference dialog box?

Clodimedius wrote:
There is a way to avoid using the overlap mode, which is very simple.
Instead of using Command T to apply the default transition and shorten the video, drag the transition from the list of transition in the media browser effects library on the right.
This way, the default overlap mode is applied, instead of using the available media.
I am sorry, but this is just wrong. The default option is "using available media", as it should, no matter how you apply the transition. Like James said, you only get the "overlap" option if there is no available media to work with.
By the way, this has been this way for quite some time already (I think since 10.0.1, but I can't be sure).

How deploy a transition using complex condition by OMB+?

Hello,
I can’t deploy a process flow package using OMB+
But, it doesn't work because of a transition with complex condition.
I will try to explain my problem on the best :
I am working in OWB 10g R2.
I developped several process flow of this modele:
- I have a package module named : PFL_MODULE
- In this package module, I have created four process flow package :
PPK_ODS
PPK_DWH
PPK_DMT
PPK_SCH
In each package I have three or four process flow.
To deploy it, I use OMB+
I created this script :
+# move to apropriate context+
OMBCC '/$project_name/PFL_MODULE'
+puts "Current context is [OMBDCC]"+
+puts ""+
+# Connect to the default control center+
+puts "Connect to the default control center"+
+puts ""+
+OMBCONNECT CONTROL_CENTER+
+puts "Deploying workflows :"+

OMBDROP DEPLOYMENT_ACTION_PLAN 'PROCESS_FLOW_PACKAGES'
+puts [OMBCOMMIT]+
+puts "Workflows are deployed"+
when I tested it, everything worked !
But, recently, I had to modify one of my process flow. This process flow is in PPK_SCH package (and it named PRC_SCH_FULL)
I had to change a transition using an enumerated condition (SUCCESS, ERROR) by a transition using a complex condition.
My condition is very simple, I test one of my variable ("PRC_SCH_FULL"."VAR_END" =1)
When I deploy my new process flow by the control center in OWB it works.
But, when I deploy it by my script I have an error message :
*OMB05602 : An unknown Deployment error has occured for Object Type DeploymentContextImpl.generate WBGeneratedObject[] is null or length 0 for PPK_SCH.*
I'm sure the problem is in transition because when I put an enumerted condition back, it works again.
So, How can I do to deploy my process flow package that contains a process flow with complex condition in a transition?
thank you in advance for any suggestions.
Jue.

If I get what you said, then you have 2 enumerated and one complex condition?
Rules for Valid Transitions
For a transition to be valid, it must conform to the following rules:
All activities, apart from START and END, must have at least one incoming transition.
Only the AND and OR activities can have more than one incoming transition.
Only a FORK activity can have more than one unconditional outgoing transition.
A FORK activity can have only unconditional outgoing transitions.
An activity that has an enumerated set of outcomes must have either an outgoing transition for each possible outcome or an unconditional outgoing transition.
An activity can have zero or more outgoing complex expression transitions.
An activity, with an outgoing complex expression transition, must have an unconditional outgoing transition.
An END_LOOP transition must have only one unconditional transition to its associated FOR_LOOP or WHILE_LOOP activity.
The transition taken by the exit outcome of a FOR_LOOP or WHILE_LOOP must not connect to an activity that could be carried on as a result of the "loop."

How to use one boolean button to control many boolean buttons?

I would like to create a LabView control interface with boolean buttons.
As my attachment picture shown, there are four boolean buttons.
The button1 is the main power, if I press ON button1, other three
buttons also turned to ON at the same time.
How do I build up the LabView program in the block diagram?
What should I do???

Controls and indicators function as variables. In a text based language, you could just write the name of the variable again. In LV, since each control only has one terminal, you need local variables to do this. To create a local variable, right click on the control and from the popup menu select Create>>Local Variable. You can have a local as read or write. Create a local for each of the buttons and wire the data coming out of the first button into the locals.
There is something that is very important to understand here - when you use locals, you can disrupt the dataflow nature of LV and create race conditions. For example - if, after fixing your code, you were to click on one of the buttons, to set it to F, it would immediately be set back to T by the running code. This can be very dangerous. Also, I see you're using the continuous run mode. You should use a loop instead. Try looking for some LV by searching google for "Labview tutorials. Also, here's one you can start with.

A transition using an image (slide an image across the screen)

Hi everyone,
Hopefully a good question I am about to ask. I have 2 clips, and wish to use an image as the transition between those 2 clips. I've seen this sometimes
on TV, where you'll see a clip playing, then a graphic is used - like a side swipe for example, coming in from the left, a graphic slides in from the left, passes
through the middle of the screen, and exits on the right, as it exits, the 2nd clip is now playing.
Does anyone know how to accomplish this ? I thought perhaps there would be a canned video transition available, but none of them allow me to
add an image to any of those effects ( for example in "slide" category under "Slide" in the video transition effect panel.
Thanks for your time !
Dave.

When you unpin it, you can go past the beginning and the end of the clip in the Effect Controls Panel.
As for getting them to run at the same speed, consider this...
You have to wait to start the wipe until the graphic is in the frame and you have to end the wipe before the graphic leaves the frame.
So, figure out the exact middle, and work both forwards and backwards from there. To find the middle of the wipe should be easy, it is generally right at the cut. And finding the middle of the graphic should be easy because it usuaaly starts there. So force a keyframe at that point by clicking on the diamond.
As I write this I realize you need to know where the center of the graphic is so that you can start the wipe when exactly half of the graphic is on screen and end it when exactly half is off screen. So start with the middle, then go to the beginning of the wipe and make sure that the graphic is half on and half off on the left. Then go to the end of the wipe and make sure the graphic is at that halfway point on the right.
The math shoulf force this to work.

Use of Boolean in Abap Object

Gentlemans!!
I'm wondering if the boolean type data exists in Abap Object and if it used when we define methods.
I used to use it in C++ and Java and I still don't know if this it's used or even exists in Abap Objects.
Thanks for your help.
Regards,
Polak.

Hello,
The boolean type don't exist in ABAP.
In ABAP we used to refer to the type-pool ABAP where exists a type ABAP_BOOL (character length 1) where X = true and space = false. To refer to these values there are two constants: ABAP_TRUE and ABAP_FALSE.
To access the type-pool use the transaction SE11 select Type Group and enter ABAP.

Need information about the transition used in this video.

Hi,
I try to make a video about a game (a fragmovie).
I have see a video with very nice transition. I want try to do same but i don't know how.
If somemone have tuto, links, tips or whatever for help me, thanks you.
The video : http://www.youtube.com/watch?feature=player_embedded&v=unWCV9aWWrc
I want do same transitions as 00:14 or 00:27sec.
Thanks.

I'd take your two clips and set them up with a simple dissolve transition between the two using opacity with the blend mode set to alpha add. Next drop the comp with the dissolve transition into a new comp or select both layers and pre-compose. Now apply Effect>Stylize>Motion Tile and animate the tile center to complete the transition.

Use of boolean returning functions in a project

Hello all gurus,
in my project, we have a fairly important packaged functions that return boolean values. Working with these ones in pl/sql is very fine. But sometimes we need to reuse these functions in SQL, but no luck because bools are usable under pl/sql only and can't interact in any way in SQL statements. So the workaround should be to use these functions to return us some Y/N or 1/0 to emulate boolean behavior in SQL statements.
Here what i tested with not luck:
-- not work
select r.role, sys.diutil.bool_to_int(dbms_session.is_role_enabled(r.role)) as is_role_enabled
from   dba_roles r;
-- not work
select r.role
from   dba_roles r
where sys.diutil.bool_to_int(dbms_session.is_role_enabled(r.role)) = 1;
-- not work
select t1.id,
       bool_to_char(my_bool_func(t1.x, t1.y, ...)) as is_something
from   t1;
-- not work
select t1.id,
       sys.diutil.bool_to_int(my_bool_func(t1.x, t1.y, ...)) as is_something
from   t1;The odd wrapping trick as a last resort solution is working....
-- Works! Seems the only way, but a lot of wrapping work...
create or replace function my_bool_func_wrap(p_x number, p_y number, ...) return varchar2 as
begin
   return bool_to_char(my_bool_func(p_x, p_y, ...));
end;
select t1.id,
       my_bool_func_wrap((t1.x, t1.y, ...)) as is_something
from   t1;I read a lot, but no elegant and working way.
Is there a more standard, elegant universal way to call bool functions from SQL?
Is creating a custom type visible and usable from both pl/sql and sql, if possible, a way to go?
Any other pointers?
For new development, is it good to make my boolean type returning functions using SQL compatible type like CHAR (Y/N) or NUMBER (1/0) ? It will make us less wrapping job, but more and less elegant bool handling code on the pl/sql side.
What is the goal to have bool only in pl/sql and not usable in SQL? It's kind of a feature incompatibility in the same product. Strange...
Thanks a lot

Finally, I'll have to dump the BOOLEAN return type to all our boolean functions and return char instead. With this I will be able to call then from SQL.... From this perspective, BOOLEAN is useless.I would not say that. Let's assume that you implement boolean in SQL as a single byte character string containing either Y or N, enforce that with a constraint and also add a not-null constraint to it.
You simply define two PL functions (not usable from SQL) that deals with the conversion. You use the one function to change boolean to char before hitting the SQL engine, and the other to convert char to boolean when getting data from the SQL engine.
As I/O routines are modularised, it means that you need to deal with these conversions once only when writing and once only when reading (per module).
Simple example:
SQL> create or replace function to_bool( c varchar2 ) return boolean is
2 begin
3          return( c = 'Y' );
4 end;
5 /

5          else

Can't change preference to apply transitions using available media

I'm trying to change the preference in FCP X 10.3 to have FC use available media for transitions. According to my official Apple training materials this should be done in the preferences in the Editing tab. That preference setting is simply not there (see attached screen shot). Has it been moved to another location or has the method been changed in this rev of FCP?

That's been removed. Unfortunately the Apple book came out early, based on 10.0 and has much that is wrong. It is now always set to use available media. If you get an error message when you try to do the transition, it means there is not available media.
