Empty variable pane when debugging

I'm fairly new to flex builder and very new with the
debugger. For some reason when I am debugging my application my
variables pane is coming up empty, no variables at all listed. Does
anyone have any idea what might cause this? My console is updating
working correctly. Its making life dificult as you may imagine.
Thanks
Adam

No. The local variables 'used' to show up during debugging. But erratically it doesn't show up local variable values. I had to restart my machine couple of times whenever this happens, inorder to see the local variable values. But this time even restarting doesn't help.
Is there any preference setup that need to be turned on/off to see local variables?
Also I can't step into a static method now. Any idea why this happens?

Format of Variables Change When Debugging

When debugging in LabWindows, the format of the variables (decimal, hex, ASCII, etc.) is always set to the default under certain circumstances. For example if you step into a function, change format of a variable, step out then back in, the format has been reset to the default. There are other instances when you run, stop, rebuild and debug where this is done also.
I've asked NI to explain why the variable format can't be retained, at least within one debug session (until exiting LabWindows). The explanation is they use a stack-based system to store this information so it is lost during debug.
I find this to be an extreme annoyance and an enormous waste of time. For example, I deal with a lot of arrays of binary data. Seeing these array values in ASCII is of no value. So I'm nearly constantly setting the format back to hex during debugging.
I'm curious whether anyone else thinks this is a problem. NI knows about this, but it's unlikely they'll do anything unless there is a lot of feedback from us users on the value of fixing this. Post a note and let me (and NI) know what you think, whether you think this is important or not.
Thanks,
Dave

Hi Chris,
Yes, using Format >> Preferences is exactly what I was talking about when I said "change the format of a variable". Thanks for giving the exact details of doing this.
I'm still using v8.1. I'm leery of renewing my service contract because I don't feel NI is listening to me (as a customer, not just a LabWindows user) regarding the issues that affect my work and ways to greatly improve my productivity. I have been suggesting this for a few years now, to no avail, both with tech support on the phone and through your product suggestion center.
I can't explain all the intricacies of the issue. Maybe what you have to do is set breakpoints and run rather than step in and out. Here's what an engineer in NI's R&D center said:
It's not actually rebuilding the project that causes the information to be lost. It's actually even worse than that. As variables come in and out of scope, the formatting and the expand/collapse state of each variable is lost. So, if you've hit a breakpoint in a function and re-formatted a local variable, and then continue debugging outside the function, eventually stepping back into the function, the formatting for the original variable is reset when the item is created anew in the variable display, based on the data type of the variable.
The problem we have is that the formatting information is stored in stack-based memory which is associated with the actual items that you see in the variable display. As these items disappear and are re-created in the variable display, the formatting information is reset.
The complexity of representing variable scope information, including arbitrary block scopes, makes it pretty hard to maintain variable information in global, non-stack-based memory. It's obviously not impossible, but unfortunately it would require a fundamental redesign of our debugging paradigm.
Finally, we have heard this request from multiple customers, and I assure you that you are not the only customer who has asked for this feature. The problem with this feature, as with many other feature requests is one of trade-off. It is obviously impossible to accept all the feedback that we receive, and so we are constantly having to weigh development costs of a particular feature, the risks involved in implementing it, and how widespread its benefits are. So far, this feature has not made the cut. However, this does not mean that we're ignoring it, or any other customer feedback. Many customer-requested features have made it into previous releases, and we're confident that this will too, in the not too distant future. As a matter of fact, we can honestly say that most new features in a given CVI release originate with customer requests. I also just want to re-emphasize that each time you reiterate how important a given feature is, it drives up its priority and makes it more likely that we will implement it sooner, rather than later. With that in mind, we definitely welcome your suggestion to post a note about this request in the forum. We expect other people to second the request, and the more people that do that, the better.
So my question wasn't posted for NI to respond. It was to find out if anybody else using LabWindows finds this issue to be detrimental to productivity.
Thanks,
Dave

Unable to see local variable values when debugging java

Hi,
I am using JDev 10.1.2 with java version 1.4.2_04.
I have been using JDev to debug my java programs. But suddenly from this morning I am unable to see local variable values. I am able to see class and instance variables. This has happened to me before and I had restarted my machine couple of time, to get this sorted. But this time, nothing helps. Going thru the forum I found out that Include Debug information (Project Properties -> Compiler Option) need to be turned ON. It is already turned ON for me.
I would greatly appreciate if you could let me know how to crack this problem.
Thanks in advance.

Fix variable alphabetizing in debug pane

I have been trying to use Director 11 for months, but have
more or less given up because of one problem that is probably very
easy to fix: when debugging, it does not appear to be possible to
have the list of variables sorted alphabetically. this makes it
really hard to use. If Adobe wants more people to use Director,
which is a great program, they have to fix this. Another killing
problem for me is that when you use a custom icon for a projector,
it is not sized correctly, and looks terrible on the user's
desktop. We can't distribute applications like that, so it has to
get fixed!!

Good one,Tim. I have filed a bug for this issue.
Thanks,
Don

JDev903 debugger doesn't display local variable when debugging into JDK src

Hi,
I found that JDev903 debugger doesn't display local variables in the "smart data" and "data" panels when debugging into the JDK src. For most of the time, it only shows "this" object.
Is this right? How do I setup JDev903 to display local variables in debugger?
thanks,
Richard

Hi Fred,
Did you forget to put resultFormat="e4x"?

The ForEach Loop Enumerator is Empty - SSIS Error when executing through CMD via VBA

I am currently working on a SSIS package that is to be triggered through CMD via VBA (Access). All that the package does is read a bunch of files from a folder and upload them into a table in SQL Server. The tricky part comes is that this folder location from
which the package is to read the files is dynamic.
I figured out a way to make it dynamic, by using variables
I have used the following variables:
"Directory" against DIRECTORY in COLLECTION>>EXPRESSIONS in the ForEachfile Enumerator,
"FilePath" (With Index 0) in the Variable Mappings
PROBLEM : As the final link in the chain, I have used following to be triggered from VBA
dtexec \f "C:\Desktop\SSISAppend.dtsx" /Set "\Package.Variables[User::Directory].Property[Value];C:\Desktop\AppendFiles"
When I try to execute the package using the above command, it gives out the error
Code : 0x8001C004
Description: The For Each File Enumerator is empty. The For Each File enumerator did not find any files that meatched the file pattern, or the specified directory was empty.
But, when I run the package from MS VisualStudio 2008, the package runs fine, takes the location of the file assigned to the variable "Directory".
All help is appreciated

Where are you executing the package from? You're giving an aboslute path so this will work only if package as well as the folder is in the same machine from which you execute the above code. Otherwise you need to use UNC path.
Another thing to check is what login is executing the command and you need to ensure it does have access to the directoty path as well as to the path where package resides.
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

How to inspect a cursor variable in a debug session?

In a function inside the body of a package I do...
Example:
V_SITUACIONESACTYHIST C_SITUACIONESACTYHIST%ROWTYPE;
BEGIN
FOR v_SituacionesACTyHIST IN c_SituacionesACTyHIST( p_id_DECE400, p_idpers )
LOOP
IF ( V_SITUACIONESACTYHIST.ESTADO_SITUACION = 'S' ) THEN
v_hay_regs_hist:=1;
END IF;
END LOOP;
where the cursor variable c_SituacionesACTyHIST is declared in the specifications package (Is this the problem, because is a global declaration?).
When debugging I cannot inspect the value of V_SITUACIONESACTYHIST.ESTADO_SITUACION or whatever cursor variable field; I always obtain "NULL" as value...
Why?
How can I see the value of that variables?
I have the same problem in v2.1 and 1.5.5 version of sqldeveloper.
Thanks.

I'm proposing that you don't have a variable named the same as your cursor variable.
CREATE OR REPLACE
PROCEDURE P1
AS
CURSOR test_cur
IS
SELECT owner, table_name FROM all_tables WHERE ROWNUM <= 10;
-- x test_cur%rowtype; /* This variable is not needed. */
BEGIN
FOR x IN test_cur /* If you don't have another variable named x somewhere, you can see values for x */
LOOP
dbms_output.put_line(x.owner || '.' || x.table_name);
END LOOP;
END P1;from your example...
V_SITUACIONESACTYHIST C_SITUACIONESACTYHIST%ROWTYPE;
BEGIN
FOR v_SituacionesACTyHIST IN c_SituacionesACTyHIST( p_id_DECE400, p_idpers )
LOOP
IF ( V_SITUACIONESACTYHIST.ESTADO_SITUACION = 'S' ) THEN
v_hay_regs_hist:=1;
END IF;
END LOOP;You're declaring your variable twice:
(1) V_SITUACIONESACTYHIST C_SITUACIONESACTYHIST%ROWTYPE;
(2) FOR v_SituacionesACTyHIST IN c_SituacionesACTyHIST
When you're debugging, it's looking at the first version...which is null because you haven't assigned anything to it. When you use a Cursor For-Loop like that, it implicitly declares the variable for you. You don't have to do it in your DECLARE section.

When debugging, a for loop is not entered even though the number 6 is passed to "N".

I cannot figure out why a for loop is not entered when I debug it. When debugging a value of 6 is clearly passed to "N", the number of iterations the loop is supposed to execute. So when I debug, execution highlighting just parses right over the loop, even though I request to enter the loop. Everything inside of the loop is not executed. Have you experienced this before? - Any ideas?

As mentioned by "eh" auto-indexed arrays that are empty will cause this.
A "FOR loop" will itereate as many times as is indicated by the smallest number elements in any of its auto-indexed inputs.
When you watch it in execution-highlighting, you probably will see a "0" coming in on an auto-indexed input.

Extendscript variables undefined when triggered from PostFrameMakerDocUpdate event

I am trying to run an Extendscript script in RH10.0.1.292.
This script is registered to the PostFrameMakerDocUpdate event so that it runs evey time I update my FM sources.
Every time I Update or Force Update, when the script runs, I get an 'undefined variable' message.
However, when I run the same script from within RoboHelp, or from the ExtendScript Toolkit, everything is fine. The script runs to completion without any errors.
Initially, the undefined variable is a global (defined at the top of the file before any functions)
var Rev = "Rev 2.3 December 22, 2013";
If I move Rev into the only function where it is used, I get another error: the numParaStyles is now an undefined variable. This is a local variable, defined in the one and only function where it is ued.
var numParaStyles = FM_paragraphStyles.length;
Although FM_paragraphStyles is a global array:
var FM_paragraphStyles = ["TipText", "CautionText", "WarningText"];
This script is is based on the Reference Page Image Updater.jsx script included in the
Adobe\RoboHTML\10.00\Scripts\Sample Scripts
folder. I added the Rev string as part of my debugging efforts,
Since the script works find from the ExtendScript Toolkit and from within RoboHelp, I suspect something is happening to mess up with the script's variable scoping when the script is run in response to an event. But that's just a guess. I am not an expert in JavaScript, let alone ExtendScript.
Has anyone else seen this behavior? Is there something I can do to prevent the error messages?
Thanks!

Extendscript doesn't work nice with globals if you are using scripting
events. In my experience, the easiest workaround is to create functions
that create globals and call that function in the function linked to an
event. Personally, I normally make a script and then add an extra
function specifically for events that initiates any globals and then
runs the script normally. There's no easy fix, sorry.
I believe this is a bug. You can report bugs to Adobe via

Illustrator crashes when debugging extension

I'm building an Illustrator extension, but haven't made much progress due to crashes that occur when debugging.
I set a breakpoint in order to view the Application object's structure. When the breakpoint is hit, the Application data takes a very long time to appear in variables view.
package
     import com.adobe.csawlib.illustrator.Illustrator;
     import com.adobe.illustrator.*;
     public class HelloWorldIllustrator
          public static function run():void
                        // Breakpoint on the line below
               var app:Application = Illustrator.app;
When I try to expand some variables with a triangle next to them, occasionally the triangle disappears as if there were no nested data. When I switch back to Illustrator, it crashes infrequently.
Windows Vista 64 bit, Flash Builder standalone.
If there are workarounds, I'd appreciate any help.
Thanks in advance!

I've been experiencing this issue too. I run CC on OS 10.6.8 with Extensis Fusion 4. I discovered Fusion 4 is not compatible with CC and have since upgraded to Fusion 5. Illustrator was still crashing, but I found in the forums that the Verdana font had to be activated in the System folder. I tried to install it there, but couldn't figure out how to do that, so I just activated it in the Font Library. After that, Illustrator opened.
You can find out more about this by doing a search for "Illustrator CC crash at launch" in the forum sections.

Can't activate the Stack or Data window when debugging or test a procedure

Hi,
I can't activate the Stack or Data window when debugging a procedure. The options in the View/Debugger menu are all grayed out. I can't provide parameter values when testing procedures. I am using SQL Developper 3.2.2. Has this feature ever worked?
Thanks,

Hi Jeff,
Thanks for the reply. You were right. I didn't have the privileges for debugging. I installed a local db and now have DBA privileges to do my learning and testing. I did a simple test that takes 2 strings and concatenates them into a 3rd variable then displays them. Seems to work except that the DBMS_OUTPUT occurs in the debug log is this normal? See below.

Adding to the content pane when a button is clicked

Hi there,
Could you have a look at my code please and tell me how I would execute the following code when a perticular button is pressed,
Container pane = getContentPane();
pane.setBackground(Color.white);
panel = new SwingOvalDrawing();
panel.setBackground(Color.white);
pane.add(panel,"Center");
If the code is left in the main method it will draw the oval when the program is launched, but if I insert the same code in the Action Performed method and press the button nothing happens, not only that but upon compiling the code the following error is shown
"local variable pane is accessed from within inner class; needs to be declared final"
Any help would be appreciated.

I tried declaring it as an object variable but still when the button is pressed nothing shows.
This is the button code
// Add the buttons.
JButton dCircleButton = new JButton("", buttonCircleIcon);
dCircleButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
     System.out.println("Button works ok");
     //canvasPanel = new Panel();
     //canvasPanel.add(panel, "Center");
     pane.add(panel,"Center");
});
