Problem with Custom container - cl_gui_custom_container/cl_gui_alv_grid

Hi,
I want to reuse the same custom container screen for a different data.
First screen there will be button 1 and button 2
if I click button 1 then calculate and display data in custom container, if button 2 is clicked then calculate and display data with in the same custom container.
For this
1. Created Custom container - CONTAINER
2. In program defined and created custom container and custom alv grid
g_custom_container TYPE REF TO cl_gui_custom_container,
        alv_grid                     TYPE REF TO cl_gui_alv_grid.
       IF g_custom_container IS INITIAL.
            CREATE OBJECT g_custom_container
                EXPORTING
              container_name = 'CONTAINER'.
            CREATE OBJECT alv_grid
               EXPORTING
                i_parent = g_custom_container.
      ENDIF.
3. Display data using CALL METHOD alv_grid->set_table_for_first_display
   every thing works great for button 1
4. when button 2 is clicked then calculate and display different set of data in same custom container which is used earlier.
5. here I used
call method alv_grid->free.
    call method g_custom_container->free.
6. create above objects once again and tried to use
call method alv_grid->set_table_for_first_display
, to reuse the same custom container 'CONTAINER' again for a different set of data and getting ABAP dump.
In debug mode, when I used the above method FREE for both ALV_GRID and G_CUSTOM_CONTAINER objects are not clearing.
Please let me know how can I reuse the same container for a different set of data when button2 is pressed.
Thanks in advance,
Krishna

Hello Krishna
I would recommend to use a different approach instead of trying to initialize your container instances:
DATA:
go_container_1 TYPE REF TO cl_gui_custom_container,
go_container_2 TYPE REF TO cl_gui_custom_container,
go_grid_1          TYPE REF TO cl_gui_alv_grid,
go_grid_2          TYPE REF TO cl_gui_alv_grid.
" NOTE: Do this coding BEFORE calling the screen
* (1) Create 2 containers
CREATE OBJECT g_container_1
                EXPORTING
              container_name = 'CONTAINER'.
CREATE OBJECT g_container_2
                EXPORTING
              container_name = 'CONTAINER'.
" NOTE: If it is not possible to use the same container name then either create an additional
"            dummy screen having a second CUSTOM_CONTROL element or replace
" the customer containers with docking containers -> here you do not need to give a container name
* (2) Create 2 grid instances using a different container
* (3) Link the first container to the screen using its LINK method:
CALL METHOD go_container_1
    EXPORTING
       repid = <...>
      dynnr = <...>.
* (4) Perhaps you need to define a second dummy screen to which you link the second container
* (5) Display first grid instance (as default)
Now when the user pushes button 2 (to display the second grid) link container_1 to the dummy screen
and link container_2 to your main screen.

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.

Problems with OLE Container in QUERY

Hi all,
I have problem with OLE Container when I am trying to retrieve data from the database. Inserting is no problem and commit is done. I am doing it with
initialize_container('block.ole_object','C:\test.doc');
I have only one column of BLOB type and it is last in the block as it was suggested somewhere on the forum.
When I am trying to retrieve the already inserted data I get error with the following
Description:
FRM-40505: Oracle ERROR: unable to perform query and CTRL+F1 says the following:
ORA-00932: inconsistent data types: expected got
The forms and the database are as follow:
Forms [32 Bit] Version 6.0.8.24.1 (Production)
Oracle Database 10g Enterprise Edition Release 10.1.0.4.2 - Production
I need immediate help!!!

This may be related to the 10g database, I'm not sure as there is no way for me to test it. I know that it works with a 9i database.
One thing to check is to make sure that you don't have the FORMS60_DISABLE_DESCRIBE set to 1 within the Oracle registry.
If this doesn't work, your only option might be to use a LONG RAW instead of a BLOB column type in the database.

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

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:

Problems with customizing select lists and popup LOVs

Hi
I have 2 problems about select lists and popup LOVs.
The first one is about a select list in a tabular form.
It should be created with APEX_ITEM.SELECT_LIST_FROM_LOV or similar and take its values from a named LOV.
This worked fine but now it should also have the possibility to enter a free value.
I tried to accomplish that by creating a APEX_ITEM.POPUP_FROM_LOV, but there is a problem with the function that is called by the arrow icon right to the input field (for eg. genList_f11_5()).
If the row is added by addRow, then it works fine, but if the row is is not empty
then the function call is like genList_f11_$_row() and the input field gets no value, when a LOV option is selected.
The other problem is about a select list which should have the possibility to enter a custom value and
also there should be the possibility to select several values. I tried to implement this by a text area containing the selected values and a multiple select list, with an event handler in each option. The user could click options and they would be copied to the text area. The problem is that I couldn't make the event handler work in IE.
I would appreciate any ideas about either of these problems.

Hi,
If you download application you can see source.
I have not write any instructions, sorry.
If you are on Apex 4 you can just load jQuery UI autocomplete library and take ideas from my app.
If you download my sample in zip there is uncompressed htmldbQuery library.
You can see that and take only function htmldbAutocomplete.
Then check jQuery UI document
http://jqueryui.com/demos/autocomplete/#method-search
There is method search that you can use open list just by click of input.
I hope this helps at start.

Problems with Custom Data Types when converting from TS 1.0 to 3.0.

I am currently involved in the process of converting a test environment from TestStand 1.0, LabVIEW 5.1, and Windows NT to TestStand 3.0, LabVIEW 7.0, and Windows XP. We use a custom Operator Interface developed in LV. Based on the entered Model and Serial number, the appropriate Test Sequence is called. We also use a custom Process Model. The steps in the Test Sequence are either LV code modules or DLLs created in C++. We have LV SubVIs and C++ API functions that allow the developers of the test steps to add data to various Custom Data Types. For example, a developer may set up a test to add a note (Step.Result.Notes[x].String) when the test fails. Step.Result.Notes is a container for an array of strings. The attempt to set a note first attempts to use SetDimensions to redimension the array, then SetValString to set the value. These notes are added to the report. On the old system, everything worked fine. A note could be added to any result. On the new system, if a note is added to say the 5th result, but results 1-4 do not have a note, the test sequence ends and the Operator Interface returns to waiting for data entry (as if no test ever happened). No report is generated. The LabVIEW libraries have been modified to solve this problem by calling SetDimensions to incrementally increase the array size by one, and populating the unused TestStand array elements with an empty array of LabVIEW strings using the SetValString call . In other words, based on the previous example, if the user wants to set a note for the 5th result, the notes for results 1-4 must first be sent an empty array of strings. The report will only display the note for Result 5 (as desired). In addition to this being cumbersome, attempting to implement the same workaround in the C++ API has been unsuccessful because even though the note arrays for unwanted notes (1-4) is initialized with nothing, it is still displayed as a note (empty) on the report. If anybody knows what is wrong and what the solution is, it will be appreciated.

Aaron,
Thanks for your reply. I will attempt to clarify. I am working with a single step. The step calls a DLL. The DLL performs many 'checks' on the UUT (e.g. Model Number Check, Serial Number Check, Calibration Constants Check, etc.). Under the Type Palette - MyTypes.ini, we have a Step Type called TEST_DLL with a container in it called Results. In the Results container are a number of things, but I will only list the important ones:
Notes (Array of Type 'Notes'; Type 'Notes' is a Custom Data Type (container, Type Definition)containing an array of strings called 'String')
-Notes are generally set when on of the checks fails, otherwise no Note is set for the check.
Val (Array of Type 'Val'; Type 'Val' is Custom Data Type (container, Type Definition) containing a Boolean called 'Boolean')
-Val indicates whether the check passed of failed
Pseudocode example:
//Model Number Check
check# = 0;
resultBOOL = ModelNumberCheck();
SetDimensions("Step.Result.Val", 0, "[0]", check#);
SetValBoolean("Step.Result.Val[check#].Boolean", 0, resultBOOL);
if(resultBOOL == FAIL)
Note# = 0;
SetDimensions("Step.Result.Notes", 0, "[0]", check#);
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Model Number Check failed");
Note# = 1;
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Model Number = 1234");
//Serial Number Check
check# = 1;
resultBOOL = SerialNumberCheck();
SetDimensions("Step.Result.Val", 0, "[0]", check#);
SetValBoolean("Step.Result.Val[check#].Boolean", 0, resultBOOL);
if(resultBOOL == FAIL)
Note# = 0;
SetDimensions("Step.Result.Notes", 0, "[0]", check#);
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Serial Number does not match expected");
More Checks
As you can see above, the "Step.Result.Val" array is redimensioned for every check. The "Step.Result.Notes" array is only redimensioned when a note needs to be added for a failing check. If the entire step executes and no check adds a note, the sequence is fine. If every check fails and therefore every check adds a note, the sequence is fine. However, if there are any gaps (e.g. check 0 adds a note, check 1 does not add a note, and check 2 tries to add a note), the sequence will stop. If I add blank notes for every check that would otherwise not have a note, the sequence completes, but the report shows the blank note.
Also, the exact code that is causing these problems runs fine on our old systems (TestStand 1.0). I hope that I clarified the problem and thanks again for the help.

Problem with same Container for 2 different outputs

Hi,
I am using method set_table_for_first_display to display 2 different output with same container depending upon the selection of radio button. but the problem I am facing is when I click BACK button after dispaying second output and executing first output, it is showing prebious output only. is there any method to handle this problem?
Regards,
Nilanjana

Hi,
On clicking back use leave to screen 0 in the PAI module of the screen.
Call screen 100.
PROCESS BEFORE OUTPUT.
Logic
PROCESS AFTER INPUT.
MODULE USER_COMMAND.
MODULE USER_COMMAND INPUT.
IF sy-ucomm EQ 'User command defined for BACK button'.
LEAVE TO SCREEN 0. "Go back to selection screen
ENDIF.
END MODULE.
Have a look at the method FREE of class cl_gui_alv_grid.
eg:
CALL METHOD wcl_alvgrid1->free
EXCEPTIONS
    cntl_error        = 1
    cntl_system_error = 2
    OTHERS            = 3.

Problem with custom tag

I have written a custom tag that I am having problems with. It works on some machines, but not on others. I have a page that uses many 'standard' tags. I have correctly set the URI etc, because all of my other tags work. However, on some machines, my custom tag gives me an error:
attribute does not support request time values
I'm assuming that I have the correct versions of standard.jar etc because all of the regular jstl 1.1 tags work. It is just my custom tag that throws an error.

Any thoughts/help greatly appreciated...

I encountered the same problem in our environment. I did the same thing as
          James. Simply re-initialize all variables in the do end tag.
          Also, with the nested tags you use you may also need to implement cloneable
          in the inner tag if the outer tag keeps references to all the inner tag
          instances.
          For instance if the outer tag kept a vector of references to the inner tag,
          then you would need to use clone() on the inner tag before adding it to the
          vector.

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 form

Hey All,
Has anyone ever experience a problem with maximizing or resizing their custom form? I have a rather large form that every time I try to maximize or resize causes Business One to hang and crash.
Any ideas what might be causing this?

Hi Curtis,
Thanks for posting the solution... will keep it in mind!

Problem with non-container managed entity manager

i am working on a project, in which i am using entity beans.i use netbeans, glassfish as application server and toplink as persistence provider .
i created a java class that handles all the operations with the entitys, which means i using non-container managed entity manager.
in the constructor
try{
            EntityManagerFactory emf = Persistence.createEntityManagerFactory("voidPU");
            entityManager = emf.createEntityManager();
        catch(Exception ex){
            throw new EJBException(ex.getMessage());
        }then i call a function in this class from a servlet
the code of the function
List users = null;
        try {
            ProgLanguages progLanguage = entityManager.find(ProgLanguages.class, languageId);
            users = (List) progLanguage.getUserIdCollection();
        catch(IllegalStateException illegalStateException){
            throw new EJBException(illegalStateException.getMessage());
        catch(IllegalArgumentException illegalArgumentException) {
            throw new EJBException(illegalArgumentException.getMessage());
        }i got an IllegalArgumentException saying Unknown entity bean class: class vanguard.server.entity.ProgLanguages, please verify that this class has been marked with the @Entity annotation
what confuses me is that sometimes it works and most of the time it does not work, have i made anything wrong?, or there is a problem with any of the tools netbeans, glassfish, or toplink?

Is it always the same entity that is reported as 'unknown' ? You mention that it works sometimes but is it the same deployment and the same code that works? The first thing I would verify is that the ear is being created as expected by netbeans. Check the persistence.xml file and verify that all of the classes are listed that will be used as entities.

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!
