... jerky unresponsive behavior with MOTION 3...

...other than reinstalling(ouch!) is there anything else after trashing preferences that might correct this problem? I've been experiencing this problem lately with the playback refusing to stop and jerky stuttering and jumping frames during playback with animations that aren't all that complex. Maybe object caches, files somewhere? thanks

There are just too many issues that contribute to Motion's terrible behavior, including, I do not hesitate to add, Apple's hyperbole. Motion wants to recalculate everything all the time in an effort to give you (the unubtainable illusion of) realtime interaction. So, if you make a tiny change that has recursive impacts, Motion will attempt to redraw from frame 01 and fill up the RAM with the newly calculated frames. This can take a l-o-n-g time depending on your preview and display settings and how much GPU power/VRAM you have onboard.
Restarting the application or restarting your Macintosh should purge all caches. Reinstalling Motion will solve nothing.
Look in the manual for "purge."
You might try pre-rendering layers that will not change, such as chromakey foregrounds, and disabling some filters or effects like drop shadows that you may not need to edit your gross movements and timing. Reactivate them when you're ready to get serious about the final look.
Sorry not to be able to point you to an immediate solution. We all have widely disparate GPUs and CPUs.

Still image with motion has flicker pulsating problem

I use FCP 5.0.4
I have read the many threads about this subject and am still not able to succeed in getting rid of the flicker/pulsating in a still image with motion.
I would say about 25% of the stills with motion have the jitters; all the rest look great.
The first thing I tried was
Effects:Video Filters:Video:Field Shift:none
as well as
Effects:Video Filters:Video:Flicker Filter min, med, and max.
Maybe 5% were corrected with this, but the other 20% still had the jitters even after using a combination of the above or by themselves.
I just burned a test DVD using a variety of the persistently jittery stills from my current project and although the jitters change a bit, they were still there so all of these failed:
1. Effects:Video Filters:Video:De-interlace Upper (odd)
2. Effects:Video Filters:Video:De-interlace Flicker Filter minimal
3. Effects:Video Filters:Video:De-interlace Flicker Filter max
4. Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
5. Effects:Video Filters:Video:Flicker Filter max
6. All the tricks together which means
Effects:Video Filters:Video:De-interlace set at Upper (odd)
Effects:Video Filters:Video:Flicker Filter max
Effects:Video Filters:Video:Shift Fields: none
Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
I know this issue has been kicked around a lot and i know some folks are not happy that it has to be kicked around at all. But I am doing something wrong because my DVDs look very un-PRO. Would anyone like to talk me through this nightmare preferably with as many details as possible since I am obviously missing something critical.
Thanks in advance.

There is no 'secret formula'. It just takes thinking through the issues.
1. Set the image size for each image that makes sense within the context of your project. Going significantly larger than the displayed area of that image (including movement) is just asking FCP to do additional work to resize the image. FCP is less sophisticated at resizing images than Photoshop. Use Photoshop and your planning of the movie to get the images to the appropriate size.
2. Wasted effort and totally irrelevant- you could set it to 7200 dpi if it makes you feel better.
3. Good idea - be sure to knock down areas of pure or very bright white. These are the elements that will give you the most trouble.
4. Don't do this unless you want to throw away HALF the picture information. Deinterlace deletes half the picture and then photoshop recreates it through interpolation of the remaining half of the picture. Why do this?
5. Make your determination based on what works. If you have properly exposed and sized the material, the need to blur is greatly reduced. ONLY do it on the images that need it. Why degrade every image if you do not need to do so?
6. See number 5
7. Lay out your time line early, view the work on an external broadcast monitor and only mess about with the images that require it.
In the psycho business they have term for much of the referenced post - it's called superstitious behavior. Basically it comes down to "It worked before so we recommend it to everyone without regard to their situation" ... here's another example:
Many years ago in my architecture practice, we had one of the early 512k macs (upgraded from the 128k!) I needed to show one of the interns how to create a project budget spread sheet in Excel. Inadvertently I clicked on Word, said "oops", closed it and opened Excel and we went to work.
A week later I was walking by the computer and overheard the same intern explaining how to work with Excel to another architect. "First you open Word, close it, THEN you open Excel", she explained. When asked by her 'trainee', why do you have to open Word first, wouldn't it just be easier to simply open Excel? Her answer was just perfect, "Well, it works every time, what's wrong with that?" so it goes ...
good luck with your project.

Dissolves with Motion'd Stills

I'm having trouble getting cross dissolves to work when I try to use them between clips that come back in from Motion, ie 2 second stills with New Camera>Behavior>Basic Motion>Move applied. Just can't seem to figure it out. I'm using a freshly installed Studio 2, an upgrade from 1.
Thanks!

It works, looks nice, but seems not the proper way to do it in the New Age.
The reasons I use handles on the .motn:
1. Give me some room to change my mind later. I need more time for movement? I need more time for an effect to resolve? I just open in editor and make some changes.
2. Allow the thing to be slipped within FCP.
I almost always use separate stacked tracks with this kind of assembly. But not because it's the olden way of doing things. It offers the most flexibility and, sad to say, whoever I'm usually editing with simply cannot grasp the paradigm of the interface where overlapped clips are on the same track.

Erratic Report Region Behavior with Dynamic SQL Queries

I'm running HTMLDB v 1.5.1.00.12 and I've noticed some odd behavior with report regions using dynamic SQL queries. Every so often, our testers will run a page containing a dynamic sql report region and get the following error, (despite the fact the query was working only moments ago and no other developer has touched it):
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
or sometimes
failed to parse SQL query:ORA-01403: no data found
The only solution I've found so far is to:
1) Make a copy of the failed report region.
2) Disable or delete the original failed report region.
The new copy of the report region runs without issue.
My search of the forums turned up the following two threads, but neither provided me with a clear explanation of the cause, and how to avoid it:
ORA-06502:PL/SQL: numeric or value error: character string buffer too small
Re: Import Export Error (ORA-06502)
The columns being returned are below the 4000 character limit, and the rows being returned are far less than 32k in size.
Could this have anything to do with the way HTMLDB is internally storing the PL/SQL used to generate the dynamic SQL Query? Is there any known issue related to this with that version of HTMLDB?
This problem occurs without any discernable pattern or consistency, making it hard to determine where I should focus my efforts in tracking down the cause.

Hi all,
My report seems to be behaving correctly once i set it to "Use Generic Column Names (parse query at runtime only)" :)
Cheers,
Joel

Strange window behavior with CS5

I have begun experiencing strange behavior with PS CS5. I should begun with the machine configuration: 2.66GHz iMac (8,1) Intel Core Duo with 4GB RAM and OSX 10.6.6, Radeon HD 2600 Pro graphics card. The initial symptom showed up suddenly as an inability to display an image window; that is, I could open PS normally, everything would show up properly, but when I opened an image file of any sort, there would be no image window. Other cues indicated that the file was open; for example, the window menu would show it selected, and the layers palette would show the file's layers.
It did not seem to matter what type of file was involved: PSD, JPG, TIF, whatever. Occasionally, this behavior would begin during a session. Sometimes it would happen right off the bat. Sometimes, stopping and restarting PS seemed to clean things up; other times, this had no effect. After messing around quite a bit with different permutations and combinations, all I could say was that the problem was random.
I might add that I've had PS CS5 on this machine pretty much since it was announced, and had not had problems with it before. So this issue came along quite suddenly a couple of weeks ago. This was a little after I'd installed an update for Nik's Viveza 2; and I began to suspect that. Although why Viveza should do such a strange thing was odd, and Viveza was never part of the files I was experiencing issues with. Anyway, I went back to an earlier version of Viveza and the problem persisted.
Since I run Time Machine, I also went back to versions of the entire PS folder from a month back, and found the same problem. Along the way, I experimented with the files I was using with PS CS4 & CS3, which I also have installed on this machine. These two versions of PS run perfectly well. At least the CS4 version has precisely the same plugins as the CS5 folder, and this seems to discount the potential problem with plugins.
To be sure about CS5, I completely deactivated, deinstalled, and reinstalled it. The same issues occurred. Now, I have to admit that I let PS run its update process so that I brought it back to the most recent version in this step of my troubleshooting. So, I can't be certain that the issue isn't with some update of CS5.
I might add that I have been running CS5 in 32-bit mode, for compatibility with certain plugins. This may or may not be an issue, since I have limited experience with running in 64-bit mode. At this point, I should add a bit more about the confusing behavior.
While messing around with CS5, I also suspected the GPU support, since my problem had to do with windows. When the problem presents itself, the usual cycle through window views that you get by pressing the "F" key seems to get messed up. In particular, the "F" key doesn't work at all. Next, if you use the View menu to select different views, the full screen with menu bar view will often have garbled pixels, while the full screen view will show a blank grey screen. Then, cycling back to a window view will show a window with blank grey contents. This is interesting since the starting point was no window at all; but going into full screen and then back will produce a window with bogus contents.
Now, the next strange thing, having to do with the GPU, is that CS5 often fails to recognize the Radeon HD 2600 card. Oddly enough, it did originally. And I had it running in Basic mode. However, CS4 does recognize the GPU; and I can set it in any variety of modes: Basic, Normal, and Advanced. This behavior is not consistent at all either; that is, while CS5 almost always now fails to detect the GPU, sometimes it does. As near as I can tell, this failure to detect the card does not depend upon whether I start CS5 in 32-bit or 64-bit mode. OTOH, CS4 always recognizes the GPU.
Another form of this odd behavior arises if I start CS5 cold, and then just open a new blank window. This almost always works. I get a blank white window, and I can paint on it with a brush, etc. However, if I go ahead at this point and open a file, then the new file takes over the window; and there are no tabs. If I select the original new file, usually labelled "Untitled", the window bar will show the change of filename but the window's contents and the layers palette will continue to show the old file that I had opened. Cycling through views can sometimes get back to the new Untitled file, but just selecting file windows never works.
Yet another aspect of this messed up window behavior is that the workspace bar, which shows the Bridge, MiniBridge and view icons on the upper left and the various workspace options and CS Live on the upper right, is present but blank. OTOH, the tool bar is always displayed correctly, as is the horizontal bar that shows the various tool options. Likewise, the palettes for the workspace such as layers, swatches, adjustments, and so on, are always correctly displayed on the left.
My next steps in trying to figure this out will be to ensure that I am running the latest of all plugins so that I can get everything running in 64-bit mode and try this again. However, the single factor that seems consistent in this whole mess is that whenever I do find this odd behavior, the performance preferences window will indicate that CS5 is not detecting the GPU. Whenever this happens, if I open up CS4 and check the same performance preference in it, the GPU is detected. I can have the two preference windows side by side on the screen in fact, CS4 sees the GPU and CS5 does not. The counter-indication is that sometimes CS5 will work properly and the preferences window still shows that the GPU has not been detected. Having said that, I can add that if I have opened up CS5, and it has found the GPU, and I have set it into, say, Basic mode, and then later found CS5 messing up, and I go back and check the performance preferences again, the GPU has always been lost. So, CS5 can mess up windows with or without the GPU detected and active; but when if it started with the GPU present, it will show up as lost after the weird behavior starts.
To add one more observation, I have had Macs and other computers with failing GPUs. This computer is showing none of the typical signs of that. Every other program seems to be working just fine, and I have a lot of these, many graphics intensive; e.g., Corel Painter 11, Parallels v6 running Windows 7, PS CS4, Lightroom v3, Aperture v3, and so on. It is just CS5 that is messing up.
I could load up this message with screen shots of all this nonsense, but I'm not sure what that would add to the strange tale, other than I'm not pulling your legs. I am, however, pulling out my own hair.
As I stated before, this began quite suddenly a couple of weeks ago, early Feb 2011. My best guess as to cause is some combination of incompatible updates between CS5, OSX, and maybe some plugin or other. I found unusual behavior with onOne's FocalPoint v2 last year after Apple updated GPU drivers in some OSX update, and cratered that program. It took onOne a month or two to fix that. I have CS5 on a laptop with the same OSX version, and on that I haven't seen these issues; but then, I haven't been using it as intensely over there. Also, that machine has different CPU and GPU models than this iMac.
So, to the community: is anybody else starting to see this odd stuff? Am I alone?

Here's the reason I say that the same plugins exist for both CS4 & CS5. Sometime last year, the internal hard drive on this computer died (as they so often do), and it was replaced under the Apple care warranty. As a consequence, I decided to rebuild the OS and applications from scratch and bring back my user files from backup. I among other things, I reinstalled all of CS4 as well as CS5 (and I had to put CS3 back too for reasons having to do with printing calibration images for Quad Tone RIP). Then, I went to reinstall the plugins that I needed. I use Nik Software, onOne, Portrait Professional and various Topaz plugins. To my recollection, most of these install in PS CS3, CS4, CS5, Aperture, and Lightroom. In short, it is not that I've copied or moved plugin folders from one application folder to another, just that the installers automatically detect the presence of the various applications and put the various plugins into each, as appropriate.
The only 32-bit plugins that I have that don't fit into this category are from Vincent Versace. He provides special versions of certain Nik plugins (Tonal Contrast, Contrast Only, etc) that function with some Acme Educational extensions for performing B&W conversion, sharpening, blah blah blah. These plugins are only 32-bit and the extensions are only CS5 compatible. I've installed these ones only into CS5; so, you've got me. OTOH, I've had these from Vincent as soon as CS5 was available; and they've worked so far without problems. Perhaps I should just edit the extensions so I could use the latest plugins direct from Nik instead of the Versace special editions...
I've checked fonts and repaired permissions. I am presently going through the rather tedious process of disabling plugins and extensions to see if anything yields consistent results. The rather random arrival of the strangeness makes ensuring that a change is really having an effect more difficult to validate, as you will appreciate.
I apologize for my long-winded original post. I add all of the detail so that anyone who'd experienced similar strange behaviors might properly pattern-match what they were seeing. On the one hand, in finding the cause of a problem, you look for what's changed; and theoretically nothing is new. On the other hand, there's always so much changing behind the scenes with automatic updates of this, that, and the other thing that it's impossible to make the claim that nothing's new.

Is it possible to create DVD Templates with Motion for burning Blue Ray DVDs from Final Cut Pro X?

As far as I know, motion templates can only be used with DVD Studio Pro. FCP X only lets you add a background image to the DVD menu.

Does anyone have the same problem with my new iMac?

Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.
First, empty the Trash.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Triple-click anywhere in the line below to select it, then drag or copy it — do not type — into the Terminal window:
find . $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl $ 2> /dev/null | wc -l
Press return. The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
The output of this command, on a line directly below what you entered, will be a number such as "35." Please post it in a reply.

How do I make interactive DVD/Blu-Ray menus with motion?

So, adobe doesn't support Encore anymore which means I can't use dynamic link to AE to create interactive DVD/Blu-Ray menus with motion.... or can I? Is there something I'm doing wrong? While in Encore, I go to dynamic link and boom, dynamic link to AE is not highlighted. If I can't make an interactive menu with motion using adobe, then what can I use? This is causing a major problem for me and my clients. (if i over looked the answer to this in another post, my apologies)

You can use the "Create After Effects Composition." This prompts you to create an independent version of the Encore PSD menu file, and opens the layered file in AE CC and creates a new composition with appropriate settings. AE no longer has mpeg export, so you export from AE to AME.
There were some workflow options that I did not play with much, but they were never what I saw as the basics for using AE to create the motion background.
You need to understand these two help pages:
Adobe Encore * Menu timing and looping
http://help.adobe.com/en_US/encore/cs/using/WSF49EA5DB-3743-49c2-9831-F66328B192F8.html

http://help.adobe.com/en_US/encore/cs/using/WSA5513911-0AD1-440c-BDAD-2E0E806B425E.html
I'm not sure what you mean by "interactive" unless you just mean creating navigation.

How do I select an image with motion blur so that I can put it onto a different background ?

How do I overlay a image with motion blur on a white background (like the first image) onto a different background (to look like the second image)? any help would be greatly appreciated, many thanks ,ed
Message was edited by: motoredd

I’m afraid you may have bitten off more than you might want to chew.
The resulting pixels of an in-camera-blur combine information about the color/brightness of back- and foreground (edit: the result of surface properties and lighting conditions) with motion (basically transparency for this task) in such a way that it seems exceedingly difficult (maybe even improssible) to isolate the foreground in a »pure« form.
One may get a halfway decent mask (as the backgound is at least almost uniform and brighter than the foreground elements) but you may have to manually decontaminate the transparent areas, otherwise the masked object in front of a dark background would have a bright edge.

Problem with Motion

I am using motion since long time. But yesterday unexpectedly my Motion failed. Dont know what happened. But now i couldn't open any existing motion file. It shows error. "Could not open file." I tried to install motion again. But it could not solved my problem. What can i do now?

Welcome to the forums. FYI, a more descriptive title can help getting a response quicker... Nearly all posts are about a problem with Motion...
See if this helps...

Strange Permissions Behavior with Public/Private Drop Box

Strange Permissions Behavior with Non-Course Drop Box
In an effort to promote iTunes U on campus this semester (and to get people working with audio and video more) we're having a contest in which people can submit personal or group audio/video projects.
This being an iTunes promo, we intend for students to submit their contributions via a drop box.
To that end, I began experimenting with drop boxes in iTunes U, which I haven't done much of previously. I've created a course called "iTunes U Drop Box Test" under "Campus Events". Within that, I have two tabs: "Featured Submissions" and "Dropbox". My goal with this drop box was to allow faculty, students and college folks the ability to use the drop box ("college" being a role I've defined for those who don't fit into the faculty/student roles).
When I first started experimenting, access to the "iTunes U Drop Box Test" course looked like this:
--- Credentials (System) ---
Edit: Administrator@urn:mace:itunesu.com:sites:lafayette.edu
Download: Authenticated@urn:mace:itunesu.com:sites:lafayette.edu
Download: Unauthenticated@urn:mace:itunesu.com:sites:lafayette.edu
Download: All@urn:mace:itunesu.com:sites:lafayette.edu
--- Credentials ----
Download: College@urn:mace:lafayette.edu
Download: Instructor@urn:mace:lafayette.edu
Download: Instructor@urn:mace:lafayette.edu:classes:${IDENTIFIER}
Download: Student@urn:mace:lafayette.edu
Download: Student@urn:mace:lafayette.edu:classes:${IDENTIFIER}
For the "Featured" Submissions tab, I gave the non-system credentials the "download" right, and for the "Dropbox" tab I gave the non-system credentials the "dropbox" right.
My understanding of this setup is that everyone should have had the ability to view the course and the contents of the "Featured Submissions" tab and that those in the College/Instructor/Student roles would be able to upload files via the "Dropbox" tab ... but not see the contents of said tab after the files were uploaded (aside from any files they uploaded themselves).
This is not the behavior we saw however. While the College/Instructor/Student roles could upload files to the dropbox, everyone (including the unauthenticated public) was able to see all of the contents of the dropbox.
The only way I could get this to work as advertised was to change all of the system credentials save the "Administrator" to "No Access":
--- Credentials (System) ---
Edit: Administrator@urn:mace:itunesu.com:sites:lafayette.edu
No Access: Authenticated@urn:mace:itunesu.com:sites:lafayette.edu
No Access: Unauthenticated@urn:mace:itunesu.com:sites:lafayette.edu
No Access: All@urn:mace:itunesu.com:sites:lafayette.edu
Once I did this, everything worked as advertised: College/Instructor/Student roles could upload tracks, and the "Dropbox" tab would only display tracks they uploaded.
So my question is ... is this the correct behavior for the drop box? It looks like when the system credentials are in play, they're simply overriding whatever the normal "view" rule is for the drop box, which doesn't seem right.

Your current configuration where things work as you wanted does seem correct to me. You are not using any System Credentials to accomplish the functionality and that's fine.
Here's some more info to clarify how / why this is working for you and why you had to set "No Access" for the System Credentials:
The System Credential "Authenticated@..." is going to get assigned to any user that goes through your transfer script. Even if you transfer script assigns no credentials to a user, upon entering iTunes U they will have at least 1 - the "Authenticated@..." credential. Therefore, unless you block access using "No Access", any user that passes through your transfer script is going to be able to access the area in question.
When you change values for "Unauthenticated@..." or "All@..." you are defining what someone that DOES NOT pass through your transfer script can do. You want both of those to be "No Access" at the top level of your site if you do not want unauthenticated visitors.
The distinction between "Unauthenticated" and "All" is that "All" applies to all users whether they pass through the transfer script or not.
Here's another way to remember things:
User passes through your transfer script, iTunes U automatically assigns:
Authenticated@....
All@....
User does not pass through your transfer script and instead access your iTunes U site through derivable URL*, they get assigned:
Unauthenticated@....
All@....
*The derivable URL for a site is: http://deimos.apple.com/WebObjects/Core.woa/Browse/site-domain-name

Get default audit field behavior with an external datasource

Others have posted and blogged extensively about creating a robust audit trail for LightSwitch. However, if you are looking to achieve the default behavior with an external datasource, you could simply add the fields to your database
and write code in every entity's Inserting() and Updating() method. However, if you have many tables in your app this can be a lot of work. Here is a very easy way to DRY this up.
1. Add the audit fields to your tables
- CreatedBy
- DateCreated
- UpdatedBy
- DateUpdated
2. Use this code in the DataService class for your datasource.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.LightSwitch;
using Microsoft.LightSwitch.Security.Server;
namespace LightSwitchApplication
public partial class ApplicationDataService
partial void SaveChanges_Executing()
EntityChangeSet changes = this.Details.GetChanges();
IReadOnlyCollection<IEntityObject> addedEntities = changes.AddedEntities;
IReadOnlyCollection<IEntityObject> modifiedEntities = changes.ModifiedEntities;
if (addedEntities.Any())
foreach (IEntityObject entity in addedEntities)
InsertAuditFields(entity);
if (modifiedEntities.Any())
foreach (IEntityObject entity in modifiedEntities)
UpdateAuditFields(entity);
private void InsertAuditFields(IEntityObject entity)
string userName = this.Application.User.FullName;
DateTimeOffset currentDateTime = DateTimeOffset.Now;
entity.Details.Properties["CreatedBy"].Value = userName;
entity.Details.Properties["DateCreated"].Value = currentDateTime;
entity.Details.Properties["UpdatedBy"].Value = userName;
entity.Details.Properties["DateUpdated"].Value = currentDateTime;
private void UpdateAuditFields(IEntityObject entity)
string userName = this.Application.User.FullName;
DateTimeOffset currentDateTime = DateTimeOffset.Now;
entity.Details.Properties["UpdatedBy"].Value = userName;
entity.Details.Properties["DateUpdated"].Value = currentDateTime;
Hopefully this helps someone.

This version will check whether the table has the audit properties, thus allowing you to opt in. Paul's solution is going to be better in the long run because it checks at compile time. This was meant to be a quick way to get the default behavior.
This is not a substitute for a full audit capability (see Paul's blog) if that is your requirement.

Strange behavior with DefaultCellEditor

Hello everybody,
I found a strange behavior with DefaultCellEditor using a JTextField in a JTable. The following line will show, what I mean:
setDefaultCellEditor(String.class,new DefaultCellEditor(new JTextField()));
Imho this should do the same as JTable does already, when it installs a JTextField as default cell editor for cell values of the String class. But, it seems, that it is not the same:
When I add this line in the constructor of a JTable subclass the editor component seems to be less wide and less high to the right and bottom - it looks so with Win95 with JDK 1.4.0 - but with Win2000 it is correct for example.
My question is - how can it be, that the normal default cell editor does not have this behavior but when I use the line above, it is displayed in the wrong way?- What does the default cell editor in another way than I do it, that it has not this ugly display?
I would like to look in the sources, but unfortunately I can't find the source code in JDK 1.4.0 - perhaps you have a hint, where to find it.
greetings Marsian

It seems the Label doesn't like it, that it is in a GridCell with rowspan = 2
If it is in a normal cell (no rowspan), it works.
If I add ColumnConstraints to the gridpane, it kind of works, but the Label still occupies more space than it should.

Strange behavior with Collections

Hello!
I have a - from my point of view - strange behavior with a List (same also applies to Vector, LinkedList, and others):
List<String> myList = new myList<String>;
myList.add("One");
while (true) {
try {
System.out.println(myList.size());
throw new Exception();
} catch (Exception e) {
e.printStackTrace();
}And the result is 1, 2, 2, 2, ...although I added only one element. The two elements in the List point to the same object.
What could case this issue?
Regards,

Strange behavior with Label#setWrapText(true) in GridPane.

I've got a strange behavior with a Label, which has setWrapText(true) in a GridPane.
Check out the sample and click the button.
You see, that the GridPane suddenly behaves as if it had GridPane.setVGrow and HGrow set for the lblStatus.
(it takes the full available space).
Furthermore the first column shrinks to a minimum, so that lblText1 can't display its text anymore.
Tested with 2.1 GA.
Any help with that?
