autoexpanding a tree works - but only once

Heya ADF-community :)

I ran across a strange behavior in the adf (latest version) and I do not know how to debug/fix it. I put a tree on initiallyExpanded = 'true' and it works, but only once.

My scenario:

I have a splitter-split page, with a tree in the left (navigation) and 'details' separator in the right. The details are inside the same page, a blender decides which section to display. (More details Re: howto: display dynamic form on the selection of the tree (11 GR 1 material jdev) )

Then. Navigate in my navigation tree, access to a node and the 'details_1' section opens and shows a part of entry fields and trees (another). This tree has the value initiallyExpanded = "true" and is initially developed.

Then, I chose another node in the navigation tree, which also highlights the "details_1" (just for another record). Iterators are defined (input fields contains the correct values) but the tree is not developed. This is the same section if the tree is the same, very, very, like work one :)

After opening some leafes and switching back and forth between the two records details the tree keeps the last State.

My tree:

                  <af:tree value="#{bindings.MagMagTree.treeModel}" var="node"
                           selectionListener="#{bindings.MagMagTree.treeModel.makeCurrent}"
                           rowSelection="single" id="mag_parenttree"
                           initiallyExpanded="true"
                           partialTriggers="::save_mag">
                    <f:facet name="nodeStamp">
                      <af:outputText value="#{node.Name}" id="ot9"/>
                    </f:facet>
                  </af:tree>

I found a blogpost by Frank Nimphius, but she came back in 2007, so I don't know if this is even necessary, or an option.

Any reference to what could be wrong? A misunderstanding by myself? An error in my logic behind this? A bug?

Hello

documentation of the component:

+ "If during the initial rendering, the current subtree under the path of target line should be expanded. A RowDisclosureEvent is broadcast from the encoding start component so that listeners are correctly informed of the disclosure. » +

So, if not you unload/reload the instance of the tree but simply refresh the tree, it is not considered as initial rendering. In this case, I think you have to programmatically set the dislosure line key on the path of the selected tree

3D Camera Tracker works, but only in 'camera 3D Tracker' no mode not "Camera Active" mode?

Here's the preview of this weird problem. (BTW, I use after effects CC 2014 on Mac OS 10.9.5.)
Step 1: Download this clip stock in the new model.
Step 2: Time reverse the clip, since that's the shot I'm looking for.
Step 3: Apply '3D Camera Tracker' and wait for analysis and camera to solve.
Step 4: Confirm a good track and choose an area target between 3 points
Step5: right click and select 'create text and Camera '.
-SO FAR SO GOOD, BUT THEN... -
Text element appears in a bad position (elsewhere in the model, many pixels away) and is not properly locked to background images, but rather floats above him like a normal 2D layer. However, if I change my display in the window of the model of "Caméra Active" now available "3D Tracker camera" view, everything looks good. I can then add other elements (text, sound, models 3D using the plugin video clip of the first officer, etc.) and they work all as expected- but only when you view the view model 'camera Tracker 3D. " Of course, if I try to, it makes on what sees the camera activates, which seems wrong.
This is the strange thing. Analysis, camera fix, etc. all seem to work well. But if I can only display it correctly in the view 'camera 3D Tracker' and not 'Active camera', then I am not able to make out successfully. I tried different tutorials on the subject and able to successfully replicate for example this one, without running into the weirdness of the Active camera. On my computer, it's a different story. Thanks for your suggestions.

Thanks again, Todd. I have found a workaround and Walter Soyka simultaneously ID had the problem - set up, they seem to be a bug in AE when followed 3D clips time-reversed. Easy enough to fix once identified and hopefully fixable in future app updates. Details here:

Ethernet cable to connect my windows laptop 7 to the internet. connection is very bad. It works but only for 30 minutes max.

My internet does not work correctly. I use an ethernet cable to connect my laptop (using windows 7) to the internet. However the connection is very bad. Sometimes it works but only for 30 minutes max, and other times it does not at all, connect saying that the cable is disconnected. I tried 3 different cables to 2 different ports, then maybe the problem comes from my laptop. It connects to the wifi networks fine but not with the cable. Does anyone have any suggestions as to what could be the problem and how can I solve this problem?

Is it possible to find the two sentences into one pdf file? For example, I know the words 'Here' and 'the answer' occur more than once in my document, but only once on the same page. I'm looking for this page.

Is it possible to find the two sentences into one pdf file? For example, I know the words 'Here' and 'the answer' occur more than once in my document, but only once on the same page. I'm looking for this page.
I tried to do this by using the search but it will find only them, if they occur as a long chain, that is to say "Here's the answer" rather than how they occur in the document it is to say "Here 's" a bunch of information that leads you to 'the answer'. The search feature so standard did not help.
Then I tried to do this by using the tool to delete (obviously not the application of writing!) because it allows me to search for multiple words or phrases, however it is not highlight what page both are found. I tried to turn on the preference to enable deletions of comments and even if it meant that I could then go through all the comments, it's still not faster than my document is more than 1,000 pages, which meant there were too many total comments for me to be able to easily identify which page had both.
Any ideas?

There is no built-in way to search for two strings and limited to show only the results that appear on the same page.

It can be done by using a custom script, however.

Research of a window does not work (but only when the folder is indexed).

As the title suggests, I can look perfectly fine and find EVERYTHING in a folder with even the most detailed search operators, but only if I index the file. I had the same problem with Windows 7 as well and I don't know how to get around this problem. I think it may have something to do with the case in question is on an external drive but I still don't understand why this is the case. Indexing is supposed to make the search faster for a specific folder, but no matter what I do, Indexing always brings Vista only returning "no matches" for each search query. If I was of the same type in one letter, he found nothing.

Assistance would be greatly appreciated.

Detected MS trackball & work, but only the basic enabled buttons.

I have an optical trackball usb IntelliPoint MS. It of that I plugged in and works. Device Manager still lists it as "Microsoft USB Trackball Optical".

It's a trackball 5 buttons-wheel scroll, but for some reason, the scroll wheel, scroll wheel button, buttons forward and back all do not work. But the trackball works as are the buttons on the left & right.

When I run mouse app in the control panel and click the "Center of mouse and keyboard", it tells me "device detected" (in spite of what the DM said.)

I uninstalled and reinstalled v2.2 (64 bit) only to get the same result. I disconnected and reconnected the trackball of the computer (connected directly to the rear of one of the USB ports on my PC.

It's weird. Why MSM & K say "no device not detected" when the DM clearly detects my "MS trackball?

Hello Mugsy,

Thanks to the Microsoft Community Forum.

Did you try to connect the Microsoft Trackball on another computer and check if it works?

Problems with a few mouse buttons occurs if the drivers/firmware is damaged. I suggest that you download the latest version of mouse and keyboard Center 2.1 64 bits and IntelliPoint 7.1 64 bit for Windows 7 from Microsoft Download link provided below.

HDMI audio still works but only my TV displays the desktop instead of what's on my computer moniter.

Hello

Hope someone can help with this mystery. I've been watching Netflix fine until yesterday, when all of a sudden the HDMI signal has stopped working. I can put a movie and hear through television, but the TV shows a picture of my office, even if the Office does not appear on the computer, the film shows. How is that even possible? Tried turning off and unplugging everything. With the help of windows 8 (and is it to be terribly frustrating)

Hello Randy,

Thank you for giving us the opportunity to help you.

I would be grateful if you can provide us with the following information to help us better understand the issue.
1. What is the brand and model of the computer?
2. Did you try to connect to a different HDMI port and check if it works?
According to the description of the signal problem HDMI has stopped working. You also mentioned that you can put a movie and hear through television, but the TV shows a picture of your desktop, even if the Office does not appear on the computer.

HDMI cables are supported, but not all, audio signals compatible HDMI video audio support cards. If your TV has an audio input, you might be able to connect an audio cable separated from the sound card of your computer directly to the TV. Otherwise, you need to connect the different audio signal to an output device, such as external speakers or your stereo. Follow these methods and check if that helps:

Method 1:

I suggest to disconnect the HDMI cable and try to connect it buy, follow these steps.

a. turn off your computer and place it near your TV. Unplug the monitor, but leave the mouse and keyboard connected.

b. connect the video cable from your computer's output to your TV.

c. turn on your TV and set it to the input that matches the output on your computer. You may need to refer to the supplied with your television user's guide for instructions on how to do it.

d. turn on your computer.

e. you should see windows displayed on your TV. If the screen looks stretched, or part of the screen seems cut off, you will probably have to adjust the screen resolution in Windows.

f. If Windows will appear on your TV, you will need to reconnect the computer to your monitor and adjust the screen resolution before connect you to your TV.

To set screen resolution follow this procedure:

a. right click on the screen, and then select the Screen Resolution.

b. check if the resolution is set to 1024 x 768.

c. If this isn't the case, then set it to 1024 x 768.

If the problem persists, go to method 2.

Method 2

When you set the outgoing SMTP server, why not specifying the SMTP server 'by' is not working, but only the first specified server?

I have several options for the outgoing SMTP server. I put a default and attempt to send. It fails and uses the first condition in the list.

I restart Thunderbird and try to send. It uses the first condition in the list.

I eliminated all SMTP servers in the list but the one I want, and it works.

What escapes me, that I have observed this problem on all my systems for a long time?

Kind regards

Carl

your lack of anything that account having a SMTP server associated with them, which, if your 'in' an account more wrinkles 'default '.

Right click on a folder in account, and then select settings.
Click on the account name in the settings and on the right is a drop down list and the value 'default' smtp for this account.

G780 keyboard does not work, but ONLY if the Elan Touchpad driver is installed.

I have a bad surprise today--unlike other manufacturers, which offers one year free tech support, Lenovo does not. $179 for a contract or $89 to cover an isolated incident. Thank you, guys. :-/

Here's my problem.

G780, bought last October. Upgrade to Win7 Home Premium Win8 Pro.

A few days ago the integrated keyboard has stopped working. It works in the BIOS, but when you start in Windows, Windows does not recognize it.

There is a PS/2 keyboard driver and device keyboard HID that appear in Win8 Device Manager. I guess these are the drivers for the built-in keyboard. If I plug in a USB keyboard, it appears in the device as an additional device keyboard HID Manager.

By trial and error, I discovered that the keyboard still works fine when the Elan touchpad driver is not installed. The problem with THAT: I can not disable the touchpad unless the driver is installed, and if the touchpad is not disabled, it will screw me up because I accidentally brush my hand against the touchpad while typing.

I also noticed that sometimes the touchpad in the system tray icon with a WARNING icon overlaid on top of it (you know, the little yellow triangle with exclamation point). I can't understand why, and I can't understand what has changed on my computer that caused the keyboard to stop functioning properly.

I tried uninstalling the Elan touchpad driver, download the latest driver from support G780 web page and put it back. No luck.

I make do with a USB keyboard at the moment, but I really need this problem is resolved.

Thanks in advance.

So I had uninstalled the drivers of momentum earlier... yesterday I tried to reinstall those supplied with the computer.

At least the keyboard worked now, but the drivers have not been properly disable the touchpad when I plugged the mouse.

Then I hit Fn - F6, not really thinking that he would do anything, but it fixed the problem.

I would have but the pilot would have overridden some setting I put with Fn - F6, but... maybe not.

Problem solved.

Hello

I suggest to go through these steps and check

Method 1:
I suggest you to update fire wire device driver and check.

The FireWire driver software update may solve problems with a FireWire connection. Use the following steps to update the driver software:
(a) to connect to the Internet if the computer is not already connected.
(b) click Start, right-click computer, and then click Properties
(c) click on Device Manager
(d) click on the plus sign (+) next to other devices.
(e) if there is no reference to IEEE 1394, as Bus, right-click on the name host controller, and then select update.

Method 2:

Uninstalls and reinstalls the fire wire device driver.
(a) to connect to the Internet if the computer is not already connected.
(b) click Start, right-click computer, and then click Properties
(c) click on Device Manager
(d) click on the plus sign (+) next to other devices.
(e) if there is no reference to IEEE 1394 controller Host Bus, right click on the name and select uninstall
(f) close Device Manager, and then restart the computer...

You can also try updating the chipset drivers

the event structure cannot combine with other events and run only once

Why it will always get stuck when I combined the 'new user add' event to the event of 'Login '?

It works for me when I separate the two, but the 'Add a new user' button can work but only once for the structure above, program will be blocked on the second time that I press the button "add a new user".

It has already been said, you must use that a single structure of the event and not 2. Also, avoid using local variables (better store data in a shift register and not in an indicator) how you do it, it can cause bad racing conditions.

Actually here you just don't another data storage since you have a file. Don't store data file to the root of the C drive, you do not have write permission. Use the default data folder or the folder of the application.

I have attached a simple example. I guess that's a work at home? Please make my account help: try to understand why your VI does not work and try to find a solution by yourself. Modify my sample and play with him. This is how you learn LabVIEW. If something is not clear, post here, and we can explain/help.

Edit: has the 'connection' event, I don't check against whether the file exists or not. Difficulty of this part, gives too little practice.
