Problems on customized TableCellEditor?

Hi, Swing Gurus
Much thanks to every guy who has made so many valuable suggestions.
But, still I have problems on my customized TableCellEditor. The biggest problem is when a user cancelled editing(e.g. by clicking the other table cell), the customized TableCellEditor doesn��t response well. And after cancellation the original value of the cell is changed to null.
To solve the problem, I find ItemListener in java.awt.event and my customized TableCellEditor has implemented it. But I don��t know if I can or how to register it on a jtable.
If not, does it mean I must intercept a mouse click event on the table and judge if it is outside the cell being edited?
Any hints?
Thank you in advance!
Regards,
Justine

Hey RGD VLB,
Thanks for the question. If I understand correctly, two iOS devices are not able to connect using FaceTime. You want to know if the OS could be the problem? I would recommend that you read this article, it may be able to help the issue.
This article covers different things that might be causing an issue.
If you can't make or receive FaceTime calls - Apple Support
Update both devices (your device and your friend's device) to the latest version of iOS.
Thanks for using Apple Support Communities.
Have a good one,
Mario

PROBLEM IN CUSTOM IDOC CREATION

Hi Friends,
                I'm facing a problem in custom idoc creation plz try to assist me
1.As per the information i have i'm creating segment in we31
for cremas01 idoc.But when i enter the name for segment i'm getting message "Name range Voilation particular name which i had given is not permitted in customer system?
Plz clarify this,and are there any formalities which i should look for before creating custom idoc?
Good answers will be rewarded.
                                                                          Regards,

The Problem might be.... with the naming of the segment.
Standard segments should be created with 'E1' and all the custom segments are created using 'Z1' and the name with 8 characters long only is permitted.

Problem with custom paper size on dot matrix printer

Hi All,
I'm using CR2008 with updated to SP2. I have a problem with custom paper size (W=21; H=14), the CR Viewer show report with custom paper size correctly but when I print it to a dot matrix printer (Epson LQ 300+) the content was rotated to landscape. If print to a laser printer the content was printed correctly. My report was printed correctly by CR10 or previous versions I got this issue when upgraded to CR2008. I aslo tested my computer and printer with orther application like MS Word the printing have no problem with custom paper size.
Thanks for any advice for me.
Han

Looking at the Epson LQ 300+ driver, I see that the latest update is from 2002. In my experience, most matrix printer drivers are not unicode. Crystal Reports is designed to only work with unicode printer drivers. See the [How Printer Driver Options Affect a Report|https://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/a09051e9-721e-2b10-11b6-f9c65c64ef29&overridelayout=true] article, page 6 for details. Also, see [this|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_dev/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do] note.
Finally, see if you can print from the CR designer to this printer and if you get the correct results here.

Problem with Customer Interaction Module in Web Channel Builder

Hello Everyone,
Facing an issue with Web Channel Builder Customer Interaction Module.
In Web channel builder we have done all the required configuration changes, but still we are not able to get the reviews and rating part in the product detail page.
We have created a new application and all the other module are working fine ,but the only module that is causing problem is Customer Interaction module. Every time we are activating this module rest modules stops working.
Can anyone please let us know what could be the root cause of this problem.
Are there any setting that has to be done ...that we are missing in?
I have studied that Product Catalogue is integrated with this module. Are there any setting that are to be done in the Product Catalogue module in Web channel builder?
Thanks in advance!

PB

Hi PB,
Did you please get any proper error / exception in log file? Did you please check the web.xml as well that there is no same application name defined.
Can you please also copy paste the log please.

Problems with Custom Paper Size and Address Book

I'm having some trouble printing from Address Book onto a custom paper size. I'm attempting to set up a notecard, and only print one at a time, rather than multiple columns as in the Labels option. The trouble is that when creating this small size, Address Book doesn't recognize it as anything other than a regular sheet of US Letter, and thus prints the address in the middle of the page.
I have no problem printing envelopes, though, which seems odd because they too go in the manual feed for my printer. The notecards are similar width to the envelopes, but only about half the length.
Has anyone else experienced problems with custom paper sizes printing improperly? I'm using an HP 4515 LaserJet, but have access to a few other laser printers. Thanks for any insight

I have had the same problem, and with the same result; Adobe Tech Support can't help or fix, after 15 hours on phone, Level 2 support. It is a software bug Adobe has, and can't seem to fix. I just upgraded to Lightroom CC, and my problem migrated with the upgrade. I print in Photoshop fine.
If you found an answer, I would appreciate knowing how to do it!
Thanks

Problems with custom buttons

I have problems with custom buttons in Captivate 5. The button is not switching from the _up stage to _over stage, but when I click on it the _down stage works fine. It is not a problem with the naming of the buttons. They are all with the same name and in lower case. I have tried with various custom buttons and the problem is the same. There is no problems with the standard buttons from the Adobe Gallery, so it is a bit strange, also strange that it is only the _over stage that causes problems.
The buttons I have made in Adobe Illustrator. Have tried both exporting in png and bmp format. It is the same problem.
Hope someone has some idea as to what can be wrong.

Hi Manish,
I have uploaded the zip file with the button files to Acrobat and mailed you the link.
Look forward to hear if you find a reason or more importantly a solution :-)
Kind regards
Rene

Problems with Customer Service AND unexplained charges!

I've been with Verizon for I-don't-know-how-many years, and through the years you are bound to have a few problems here and there but some of the problems are just ridiculous! It's also the same reocurring problem!!!!!!!!!!!!!!!! I was with Alltel first, before it was bought out by Verizon. The years I was with Alltel, I didn't have near as many problems. It seems EVERY time I do the smallest change or something to my phone or bill, I get a ridiculous amount of charges that I was NOT aware of, nor told about... EVEN IF I ask "So this isn't going to change my bill, or there will not be any unexpected/unexplained charges that I don't know about?"... BUT not matter how many times I ask... and NO matter how many times I am told "no"... there always is. For example.... last year, I updated and signed a new 2 year contract and purchased the first Driod. Before, my 30 day warranty was up, I was having problems with my Driod, and decided to send it in and get a new one. Before I did this.. I called customer service to make sure there would be no interuption in my bill, and there wouldn't be any unexpect charges, and there would be no difference in anything. I was told there was not, and once I recieved my new phone, just send it in and nothing would be changed. Of course, when I get my bill.. I see I was charged $500 for the new phone. It was explained to me that my credit card was reimbursed (which I never check that card, because I never used it expect to purchase the phone) and that I was recharged for the new phone, since it was a new phone. So I had to fork out the $500 (on top of my bill) and then wait months to get the $100 rebate card. Months after that, I "assumed liablity of my line" because I was on a plan with my family. I decided to have my own line, so I "assumed liability." I was not told that when I did that, I "renewed" my contract date. So I just added 6 more months to my 2 year contract. Was NOT told about that! Then again...... I was recently having problems with my Driod (the screen went black and would not come back on.) I had to turn on an OLD motorola razor, so I would not be without a phone for two days while I was waiting on my phone to come in. As soon as my phone came in, I had my Droid turned back on. I recieved my bill recently, and my bill was $200 over what it normally should be.... so I called in... apparently, when I had my phone replaced, they dropped off my data package and when I recieved my replacement driod, they never put it back on. So I was being charged for alllll my data usage... again I was NOT told about this. I wasn't even aware that they had dropped off my data package, and when/where did they get the authority to do that??? These are just a FEW of the problems that I have had.................................
Does anyone have these reoccuring problems!?

I understand that my bill can be viewed online, and I do view it fairly regularly, so if there are any unexplained charges, I can call Verizon asap. The problem does not come from me not understanding my bill, but from customer service. I have been with Verizon for a very long time, and it is a continuing problem. Where did Verizon get the 'OK' to drop my data package off my plan? Who authorized that?
After calling Verizon and trying to find out the problem, the gentleman told me that when I activated on old phone while I was waiting on my new Droid to arrive, my data package was dropped off and I "should" have been told about that. When I reactiviated my new Droid, I "should" have called and had them restart my data package. I was not aware that when you activate an old phone that data plan is taken off your plan. In all my years of having cell phones, I never make two years with one phone. I have always, at one point, had to turn on an old phone, and my data package has NEVER changed. Why would I have my data package dropped and why would I have to call Verizon to have it restarted. I would never know to do that unless I was TOLD that my data packaged HAD to be re-added when I recieved my new phone, but I was never told of that.
All of that is beside the point, the point is, Verizon was never given the authorization to change my plan. Never. My bill was taken care of and readjusted, and I am thankful for that. It does not change the fact it is always a hassle with Verizon Customer Service and I am always the one having to PROVE that I am not at fault, or that I was NEVER told of certian things. EVERY TIME I HAVE CALLED CUSTOMER SERVICE, I AM TOLD "I'M SORRY, THEY SHOULD HAVE TOLD YOU THAT."
"they should" does not help my bill with the extra armount of charges.

Problem with custom validated data types using domain on 11g

Hi,
I ' m on a migration process from 10 to 11 and I notice that a custom domain didn't work correctly anymore
to be more specific every time that I was submiting a page a was getting an error cannot convert from myclass to oracle.jbo.domain.String
I search the forum and I saw a similar problem
Cannot convert type class java.lang.String to class oracle.jbo.domain.Clob
at which Frank says that it is a known bug and suggests a work around.
I use the workaround and it worked but some more issues came up:
1. If the validation fails I get the error that I throw at the validate method not in a popup with just my message
but in the whole window with the whole error stack, meaning that my custom validation is not handled like native ADF validation errors by
the framework (at 10.1.3.4 worked OK)
2 If i dont give a value at the attribute in the validation phase mdata variable is not null but is length is zero (at 10.1.3.4 its value was null)
public class AFM implements DomainInterface, Serializable {
public AFM(String val) {
mData = new String(val);
validate();
private String mData;
protected void validate() {
// ### Implement custom domain validation logic here. ###
mData==null // returns false
mData.length()==0 // returns true
3. Can i force validation only for new or updated values? I saw that the validation process is taking place every time a row is fetched.
This is not only a performance issue, the bigger problem is that if a fetched from the DB value fails the validation an error is return but the
user cannot change the value to correct it.
TIA
Tilemahos

since i don't get any answer I wonder if i should have use a more provocative title like
"custom domains in 11g don't work"
is it true?

Problem with custom control and focus

I've a problem with the focus in a custom control that contains a TextField and some custom nodes.
If i create a form with some of these custom controls i'm not able to navigate through these fields by using the TAB key.
I've implemented a KeyEvent listener on the custom control and was able to grab the focus and forward it to the embedded TextField by calling requestFocus() on the TextField but the problem is that the TextField won't get rid of the focus anymore. Means if i press TAB the first embedded TextField will get the focus, after pressing TAB again the embedded TextField in the next custom control will get the focus AND the former focused TextField still got the focus!?
So i'm not able to remove the focus from an embeded TextField.
Any idea how to do this ?

Here you go, it contains the control, skin and behavior of the custom control, the css file and a test file that shows the problem...
control:
import javafx.scene.control.Control;

Printing Problem with custom size paper in Illustrator

Hi having problems with my custom sized paper print using my canon printers it's the same on both the ip100 and the pro-100s, it was printing fine until i've updated my illustrator and mac os Yosemite, it prints the image at a reduced size on the paper to what it should be does anyone have any understanding of this? I've tried everything i know, is this a driver or system problem?

Hi there wasn't an option to set the default printer to pdf where would I do this?
I've done a bit of a work around that seems to be working. I've put the page set up as A4 and then clicked on the printer utility custom settings and then unticked detect paper width, so I can put through the paper I want just got to tweak the x and y to get it right, its not the best but sitting here for four hours trying to figure it out, it will have to do for now. Thanks Jacob for your help, no doubt I'll be back in the morning, I'm burnt out now!

Data provider problem in custom item renderer

I have a complex, custom item renderer for a list. I add
items that I extracted from an xml to the data provider using the
IList interface. But when displaying the list, the items are all
screwed up. Each rendered item has some parts which are initialized
as different components depending on the values from the xml. This
initialization is called in the item renderer for the
creationComplete event.
The weird thing is that when I output the dataProvider to
check its values, some of the items have internal uids sometimes
and sometimes they don't. If I output the dataProvider right after
I add the items to it, none of them get internal uids. But from the
initialize method, some of them do and some don't.
To make things weirder, sometimes, as I scroll up and down
the list, the dynamic components get all switched up. I'm either
having a problem with internal uids or with the creation policies
for lists. Or it's probably some simpler mistake I have yet to see.
Anyone have any idea where the problem could lie? Any help is
greatly appreciated.

Any successful render must:
1) override the set data property of the component
Further, best practice is to store any data you need in the
override set data(), and call invalidateProperties(). Then do the
actual work in an override commitProperties() function.
The framework is smart about when to call commitProperties
efficiently. set data() gets called much more often.

Post goods receipt problem of customer returns material

hi,
i have a problem while doing customer returns in VL01N (PGR).system displays error msg.
E VL 171
Status of inpection lot xxxxxxx / partial lot 00000 does not allow goods issue.
Material having inspection set up on material master with inspection type-06
can u tell me how to solve this.
thanks in advance.

Hi prakash
In MMR i think you must have assigned a quality inspection as 06 . so at the time doing delivery , and before PGI , quality inspection took place. Now when you are doing PGR , i think you just check the goods insepction data at item level in delivery data . and remove that quality inspection 06 and then save it . then only PGR will happen .
Because you have assigned qualtiy inspection in MMR , system is checking , wheather the goods are good or not .that could be one of the reason it is not doing PGR, if u remove that 06 which is goods inspection then PGR will be done , then you can proceed further
Prakash if you have done in adifferent way plz share with us and if it got solved also plz let us know
