Wait at Rendezvous bugs

Bug #1 - Deadlock due to improper error handling
There is a bug, IMO, in Wait at Rendezvous.vi that can cause deadlock. I'll explain.
As you can see in "Wait at Rendezvous.vi", an error that flows out of "Release Waiting Procs.vi" will cause the Enqueue Element function to fail -- it will not enqueue the single element (rendezvous object data). This means that the rendezvous object is locked and cannot be accessed anywhere else.
For example, if one tries to call "Destroy Rendezvous.vi", the call to Dequeu Element in "Destroy A Rendezvous.vi" will wait forever.

NI should fix this inside their queue functions. Ignore error in, but create error out. - For what its worth, I totally disagree... I think that current behaviour is correct and consistant with other components in the environment. If an error occurs before the enqueue element primitive then it shouldn't do anything as the data coming from the previous function could be defective... resulting in an unintended message being sent to some other location in the program causing more problems. No no no this would really suck.
If the program needs an element to be enqueued (e.g. in an SEQ implementation) then it should be the responsiblity of the programmer to handle it appropriately. That is, I agree 100% with your initial statement
Here's my approach to #1 - Basically my rational is that if the subVI returns an error its output can't be trusted and I don't want it do anymore damage (e.g. stop the bleeding). Since I dequeue outside the error bypass I know that the queue reference is valid so just re-enqueue the existing element.

Is it really worth to update to 2.2 or wait till the bugs(if any) are fixed???

There are many of us here, still a bit confused after reading many threads, to install the new Froyo update, when available.
Is it really worth this update to 2.2 or wait a few weeks for the bugs(if any) are fixed???

Ranked in order of annoyance:
1. Takes longer to charge I would say almost double
2. Battery life is worse with use, standby seems to be the same. WiFi radio definitely uses way more than it used to. I used to leave it on and always leave it off unless needed.
3. Scrolling on flash sites very slow.
4. We already had flash "lite", flash 10.1 does not seem to be any better at all.
5. Crammed more bloat ware onto the device.
Pros: (no order)
Device is faster just a tad, but not enough to justify the loss of battery
Flash light app is good
HD recording seems about the same as my other 720 so its just nice to have it
App to SD is not really a benefit with Incredible because we have so much app RAM on the device anyway
Auto update from Market
Chrome to phone is great!
Wireless N is good but really no benefit due to battery use
New voice search/integration
That's my 2 cents

My ipad just won't let me enter my apple password on FaceTime or iMessage, it works fine on my iPhone, I have tried numerous things but nothing works, can anybody help please, will a bug fix sort this out when they finally make one

My ipad just won't let me sign in with my apple password on FaceTime or iMessage since updating to ios7 it says check my network connection, even though my iPhone works fine with the same password, can anybody help please, I have tried numerous things but nothing works. Will I have to wait for a bug fix to sort this? I hear they are working on one a the minute, I hate ios7

Try a Restart.
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
Resetting your settings
You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple.
Here is a link to their contacts with most of the information below.

Cirrus has a bug for a long time

[ Before start a discussion, I tell you that my English is not good. If you read kindly, I appreciate you ]
I found a bug from Cirrus network connection in AS3.
But I liked Cirrus very very much, because It needs no AIR Runtime for Server and has UTP Hole punching and etc...
So I just waited and waited that the bug will fixed by ADOBE.
I wanted it very very much.
But a few years laters, the bug still exists.
I explain the bug on this post.
[Server] Netstream.publish('name')
[Cient] Netsteram.play('name')
This methos makes Cirrus connection between Two peers finally.
I followed example code sincerely in Adobe document.
It succeed.
But It failed sometimes.( This is the bug! )
## FEATURE ##
1. There is about 40% probability of fail to make a connection.
2. There is no event of disconnection.
3. There are no error messages and any no response of failure of connecting.
4. If server's IP address and client's IP address are same, It succed 100% to make a connection.
5. If a client fails to connect a server once, the client will never succed to connect same server even though It tries again and again.
If the client has to connect the server, the client needs to refresh the program to gets a new Netconnection ID.
6. If a client fails to connect a server, another clients have some probablities to connect to same server.
I made many online games with Cirrus and a lot of users are playing with that.
They need safe connecting method very much.
Please help them and me.
Thank you.

1. P2P connections are not always possible depending on the configuration of NATs and firewalls. for an explanation, please see this posting:
https://forums.adobe.com/message/1064983#1064983
to understand what's really happening, please see
http://tools.ietf.org/html/rfc7016#section-3.5.1.6
2, 3. there should be an event after a timeout, around 2 minutes.
4. that's expected. the "behind NAT" local addresses should be reachable on the same computer.
5. that's expected. the failure to connect is because a P2P path can't be found. see answer 1 above. however, you don't need to reload the SWF -- you just need to make a new NetConnection to get a new peer ID.
6. that's expected, see answer 1 above.
since P2P connections aren't always possible, you might need to provide a server for client-server-client fallback when P2P doesn't work.

Problems / Bugs / Improvements we have found - Experienced users.

Hello there,
I work for an animation / film company and After Effects is an integral part of out production services. As much as we love the program, its not without its flaws. Here are some things we have found after using After Effects day in and day out...
Clone Stamp :
Please can you add a keyframe-able 'offset' feature to the clone stamp source region? It seems that there isn't a great way of doing this without expressions. We found a workaround which is to offset the centre point of the tracker before we do the track, then parent the clone source region to this point. Theres a lot of people online who think the cloner is completely broken for use in video, but the problem is that theres no easy way to parent the source region to a tracker...
Rendering :
Practically every day we turn up to work and find that a lot of renders weren't successful. This causes us lots and lots of unnecessary stress and problems. If there is any stability fixes that you can do then we would be highly appreciative. (Possibly just making it so that the ram is purged after each clip is rendered? - It seems to be a memory problem half the time even though this machine has 64GB of ram...). Renders also seem to be excruciatingly slow at times, even though were using an extremely powerful machine; is there nothing that can be done to accelerate renders and/or use more of the computers resources? We have found that sometimes if we pre-render a comp, it renders pretty instantaneously when in the render queue, whereas we have seen the same comp stuck doing barely anything in the render queue for hours..?
Additionally, can there be a way to change the render path/settings of multiple renders in one go? Unless were mistaken, it seems like each clip has to be manually set up and this is extremely painstaking when working with a lot of files! Also media encoder doesn't seem to render files accurately quite a lot of the time, not sure at all where the problem is but we have totally stopped using this way of rendering now as the renders rarely come out as expected.
Switching between comps:
PLEASE can you create a MASTER FX switch, which will turn off ALL the effects and motion blur in the entire project (not just the comp you are in)? This would be an amazing feature as we spend SO much time just waiting for heavy comps to open just so we can add them to the render queue... Possibly this could not effects the final render, but just allow you to quickly get into a comp? We know that caps lock stops any preview being loaded but there are many limitations to this approach.
Motion blur:
Sometimes we notice that if we have motion blur switched on inside of pre-comps, the blur is being calculated and applied multiple times, which looks horrible and takes forever to calculate... A master motion blur controller is long overdue in After Effects and programs such as Nuke have had this feature since day 1. We would love to see this feature and i'm sure there are many others who would too!
3D controls:
We would love to see better 3D controls for positioning layers etc - if there were improvements on the 3D manipulation tools (Rotate,translate,scale...) to resemble the look of a full 3D program, our lives would be much easier .
Mesh warp / Nulls:
It would be amazing to be able to parent points on the mesh warp to a null object, or at least give every mesh warp point a positional value. This would enable animators to create much improved 2D rigs for characters etc! At the moment the mesh warp isn't very robust and is difficult to get the desired control and effect.
Lens blur/Depth of field:
Can you please add an easier way to see what is in focus and whats not, when using a depth pass? There is a great feature in Nuke which allows u to see where the depth of field is taking place called 'focal plane setup', but it seems that after effects is a case of trial and error when dealing with this kind of task! Would also be amazing if you could simply click the area you want to be in focus (like in Nuke )
Duplicating comps and child comps:
PLEASE can you add an option to duplicate a comp as well as all the comps inside of it? If your dealing with complex projects it is horrific to have to go in and duplicate the comp then ALT drag the duplicate in so your not destroying other comps linked to that comp (hope that doesn't sound too confusing!). There are some scripts when claim to add this functionality but we've had no joy with any of these so far...
Multiple comps / new viewer problems
This is a big one for me and my colleagues. When there are two comp viewers on screen, please can you make the timeline switch to the corresponding comp when you click within the viewer window? Its a huge pain to have to switch between timelines when your doing this! Please can you also add the option to add real time updates in both comp viewers when you have two comp viewers on screen? It seems that only one updates in real time which can be pretty annoying...
I think thats everything for now, it would be amazing if you could rectify some of these problems as i know it would make a lot of people very happy!
Cheers!

Some of the issues you're describing already have fixes underway. Specifically rendering and switching between comps. The Adobe folks have said that the majority of the After Effects team is working on making AE behave differently (much more quickly) in interactivity and rendering. As I've heard it described, it sounds a lot like it'll answer both of those issues.
I believe I speak for all of us who use AE every day when I say, "We cannot wait! (Well, we can wait until the bugs are squashed...but you know what we mean!)" If you missed the initial public discussion on this: Happy New Year! ~ and a question… The overwhelming response to that question was FASTER! And the AE team listened. YAY!
Please have you (and everyone on your team who cares) file feature requests for the rest of these too. It would be great to be able to have the functionality of the True Comp Duplicator script a little more robustly and integrated into AE! And the DOF thing is a biggie too. Adobe - Feature Request/Bug Report Form
The folks on the AE team do listen to feature requests and the more they get for a certain feature, the higher priority it gets.
This is just a forum for users to help each other. Granted, the AE team is great about looking in too, but feature requests are the official way for them to track these things.
And, hey, EVERYONE ELSE reading this; file feature requests too! Adobe wants us to stay subscribed and happy, so let them know what we need/want.

Bugs in PDF workflow/ Quartz Filters?

I've noticed several issues with PDF workflows in Lion that seem to have gone wrong. Whether deliberately or not, I don't know.
1. If you Export a PDF from Preview with a Quartz Filter, that filter is not applied to the copy of the PDF in Preview's window, though the file on disk does get the filter applied. If you close and reload the PDF, the effects of filter will be displayed.
2. If you create a new Quartz Filter in ColorSync Utility, it doesn't work.
Even duplicating an existing system filter, like "Gray Tone", doesn't work when you apply it to a PDF document in ColorSync Utility.
3. If you do have any user quartz filters, they don't show up in Preview's Export file dialog, unless you copy them from ~/Library/Filters to ~/Library/PDF Services.
There are several webpages about this.
4. Save As PDF-X has disappeared from the PDF button of the print menu.
I have seen other webpages that mention this.
All these issues are on both of my Macs, so I don't think it's a local problem, though I would be grateful for any confirmation.

Thanks Benwiggy for that tip.
I am still running Snow Leopard due to things dropped in Lion.
I needed fax capability before I could move to Lion.
I was also waiting for the bugs to get worked out because I will lose some time when changing over.
I still have the menu item with Snow Leopard but the work flow for PDF-X is now broken as well.
I have not always had Acrobat pro.
I am famialure with inserting, extracting, and typing information on PDF documents as one would need to do in an office.
I had always used preview and the PDF-X "save as" feature to embed fonts.
I see there is a save as format to "PDF/X" in Acrobat Pro v9.0.
There is a settings button next to the save as box.
It has four different settings or flavors of PDF/x:
PDF/X-1a
PDF/X-3
PDF/X-4
PDF/X-4p.
Then there is a conversion box that allows input of a "conversion profile".
There there is a viewing or printing condition box as well.
As you can see I don't work with colors much. It is all about preserving the text and images in a document as everything is usually black and white or grey scale.
What setting for PDF/X would you suggest if "font" embedding was an issue and it was desirable to preserve the text and images as they were, without regard to color correcton.
Thanks in advance for your reply.

Yet another iMovie 6 bug-Crashing!

Why did I have to upgrade on both my drives? Buggy, buggy, buggy. Transitions don't work properly, neither do video effects and it has a tendency to crash. But, hey, great-looking box!
I wish instead of coming out with all these fancy new features, they'd concentrate on making the software stable.
But, hey, that's just me.

These are projects started in iMovie 6. Yes, I'm having some issues with 3rd party plugins. But they worked fine with the previous version. And, anyway, so few transitions and effects come standard with iMovie—what else are we supposed to do? I'm finding the new preview irritating. It decides for itself when it loops and when it doesn't—so I have to keep turning it off. Sometimes the update feature doen't work. Sometimes I get white frames at the end of pictures placed in the timeline so I have to go back in and clip them off. Updating clips sometimes causes transitions to re-render funny and the whole block has to be removed and recreated. And, in general, the new interface seems fancier but is more cumbersome to work with and takes longer to do projects. I've also had issues exporting finished movies.
In general, it feels like a beta version and I didn't have the sense to wait until the bugs got worked out. My bad. Each first effort seems a little buggy, but this one is the least stable yet. It's almost like the marketing people are telling the programmers when the product is ready rather than the other way around.

Code Coloring Bug: Ranges in DateFields

Adding ranges to DateFields in an mxml file will cause the
code coloring to stop working. Is this a known bug?
Try a field like this:
<mx:DateField id="dtNeeded" disabledRanges="{[{rangeEnd:
new Date()}]}"
selectedDate="{detailObject.dtNeeded}" editable="true"
/>

That "complaint thing" is the bug reporting tool, there is no
bug
tracking system, its the only way your going to be able to
communicate
with Adobe about the bug. There is no list of bugs, and you
will never
know for sure if/when it will be fixed. If your lucky you may
get a reply.

MobileMe iDisk App: Icon Bug

The MobileMe iDisk application appears to work as advertised but the icon on my iPhone is the one for an app called ShoppingList. I have reset my iPhone twice and deleted and re-installed the app twice, as well as deleting it from my iMac and downloading it again from iTunes (Store UK) but the icon still changes on the iPhone. On my iMac, the icon is as should be.
So I now have two different apps with the same icon on my iPhone. Anyone else experiencing this bug? This hasn't happened to any other app I've purchased on either of my iPhones.
This is on my iPhone 3G S.

iTunes Store Support got back to me today and this is what the kind folks suggested:
+I see that your in app purchase is not working as expected. I understand how frustrating this must be. I can certainly appreciate how eager you must be to resolve this issue. The developer of this application, Apple Inc, is the best resource for assistance with this issue. To contact them, please visit:+
+http://www.apple.com/support/mobileme/+
+The article below may also be helpful; I found it for you on the Apple website:+
+Troubleshooting applications purchased from the App Store+
+http://support.apple.com/kb/TS1702+
I appreciate their help, but do they appreciate the irony of directing me to Apple Inc.?
Anyway, I've already tried the troubleshooting suggestions but to no avail.
I'll wait for the bug to be fixed with an update.

With all the problems related to firefox 4.o on this forum I want to know whether upgrading to 4.0 is advisable until bugs worked out???

Can someone with more expertise who has used 4.o for awhile tell me weather upgrading now is advisable or should I wait until the bugs are worked out?????

how do you figure whether the addons one uses is compatible with 4.0?
Thanks

Overridable calculations...bug?

Has anyone been able to implement a field that is calculated, but can be
overridden? I have created a numeric field that calculates a value
based on two other fields. I then selected the field type to be
"Calculated - User Can Override". The calculations occur successfully,
however, if I attempt to override the calculated value, as soon as I
exit the field it replaces the typed-in value with the calculated value
again.
I have also trying experimenting with different values for the
'override' property on the Calculate object in the XML source, but
nothing seems to change the behavior. It doesn't appear to be behaving
the way the XFA Specification says it should.
Is this a bug? Is there any other way to allow overrides of calculations?
Justin

Jon,
What Ricardo is suggesting is a workaround to the Acrobat 7.x bug where a field whose value is calculated yet overridable cannot, in fact, be overridden in the way XFA specifies that one should be able to do.
When you set a field's Value Type to "Calculated - User Can Override" (using the Value tab in the Object palette), that's supposed to define a field with a calculated value (via script) which the user can opt to override with a specific value that, once entered into the field, shouldn't change.
The problem is that while Acrobat 7.x lets you override the calculation by entering a number in the field, once you press Enter or click away to commit the override, it's completely ignored and subsequent calculations use the calculated value from the script instead of the value that was specified as the override.
Using Ricardo's workaround, you can achieve the desired functionality without having to wait for a bug fix in Acrobat 8.0. Essentially, Ricardo's workaround is using a hidden check box to determine whether the calculation has been overridden. When the user enters a value, it's considered an override and the check box's value is set to 1. Then, when calculations are run on the form, the field's calculation script first checks to see if the check box's value is 1. If it is, it just uses the value already entered into the field. Otherwise, it uses the default script.

Hanging during waiting for changes

I just downloaded iOS 7 for my iPhone 4S yesterday. Now it won't sync with iTunes. During the sync process it hangs at the "waiting for changes to be applied" step. Any ideas on how to fix this or do I need to wait for a bug patch from Apple?

New VMS/IPC boxes - speed and pricing

For the most part, I've been a very happy FiOS customer. The internet side has gone out exactly once in the year I've had the service, and it was restored within an hour. TV has dropped out twice, both times very late at night (I assume for head-end maintenance). Reliability is better than every other ISP I've ever had, combined.
That said..
I wanted to snag another STB for the house - found out the local stores had all been closed (I can understand why from the financial aspect, but it was still a shock pulling up to my old store to pick up another STB.. and finding a "for lease" sign, when I'd been by there 2 months prior), so I looked at options online. The new VMS + IPC boxes looked promising, especially since they added the ability for the entire house to pause, rewind, schedule recordings, etc, from any TV - instead of only the DVR being able to do that (though the old boxes could stream recordings from the DVR).
My chief complaint so far - while the VMS box itself is responsive, the IPC boxes are painfully slow to respond to anything. Picture quality is fantastic, but using them feels, to put it in nerd terms, like using a Pentium 90 with Windows XP and 128MB RAM. They take 5+ to respond to anything more than a channel change (and even that takes up to 3 seconds), and frequently "lose" remote key presses if you try to, say, hit guide, hit page down, then try to arrow down to the channel that you know is on the next page. It literally feels like a throwback to the earliest digital set top boxes from Comcast/Time Warner - the first ones with built-in TV listings in the mid 1990s. The speed is right on par with them; the only thing faster right now is they don't shut down for 30 minutes a day to update the TV listings.
I've gone through the built-in diagnostics on the boxes to verify signal levels - they're decent (not perfect, but this is a 20 year old house with mostly original coax), but we have no pixelation or picture drop-out, so I would think they could carry the basic stuff between the IPC boxes and VMS pretty easily. The router certainly has no problem handling the 75/35 on the same coax (speedtest shows 85-90 down, 35-40 up, with a ~5ms ping, no matter which cable outlet it's plugged into)..
My other complaint - why did Verizon move to "rooms" for pricing? I thought I was getting a DVR plus 3 STBs (since I ordered 3 STBs and asked for a DVR), instead of a VMS + 2 STBs - and I'm paying much more than I did for the old DVR + 2 STBs.
With the griping out of the way - is there a reasonable chance that firmware updates will help with the speed of the IPC boxes? Or is there a chance it's a cabling issue? (I have no problem pulling new coax or cat5e, and I can provide signal levels if that'll help) If not, is there any chance of getting the old QIP7232 DVR + QIP7100 box back (and adding another 7100), and switching back to what I was paying before? I know they're a bit antiquated (especially the 7100s), but they were much more responsive, and didn't make me want to throw the STBs through the window. It just seems really rediculous that I'm paying such a large premium (plus the "upgrade fee") for equipment that, in terms of the user experience, is much worse.
Again.. been a happy customer for a long time, but the new terminals are super painful to use.
Thanks.

If this is the case. I think I will wait till the bugs are worked out
Question what were you paying before and after for the boxes. So what was the old DVR + 2 STB's and the new DVR plus 2 stb's
Trying to get an idea of what you meant by way more. Most people said same pricing and a small $20 or so upgrade fee
