Navigation with a checkbox

Hello,
I am trying to navigate to another page within my application upon the click of checkbox. Obviously since there is no action attribute, I need to write my own custom navigaton handling. In the valueChangeListener method of this checkbox I have the following:
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler navHandler = context.getApplication().getNavigationHandler();
navHandler.handleNavigation(context, null, "myNewPageAfterCbxClick");myNewPageAfterCbxClick is defined as a navigation rule in my faces-config, but when this code is run, I get the following error:
java.lang.IllegalArgumentException: "{2}" Conversion Error setting value ''{0}'' for ''{1}''.Any idea what I am doing wrong?

I am using a selectBooleanCheckbox. Here is the code:
JSP:
<h:selectBooleanCheckbox id="external_cbx" value="#{summaryBB.showExternalView}" valueChangeListener="#{summaryBB.showExternalViewListener}" rendered="true" onclick="submit();" immediate="true" tabindex="1"/>Backing Bean (summaryBB)
private boolean showExternalView = false;
public void showExternalViewListener(ValueChangeEvent e) {
 Boolean b = (Boolean)e.getNewValue();
 this.setShowExternalView(b.booleanValue());
 this.fillList();
 NavigationHandler navHandler = TqrUtils.getFacesContext().getApplication().getNavigationHandler();
 navHandler.handleNavigation(TqrUtils.getFacesContext(),null,"summaryExternal");
public boolean isShowExternalView() {
 return showExternalView;
public void setShowExternalView(boolean b) {
 this.showExternalView= b;
 Faces-Config
<navigation-case>
 <from-outcome>summaryExternal</from-outcome>
 <to-view-id>/jsps/CommunicationSummaryExt.jsp</to-view-id>
</navigation-case> And the stack trace is:
java.lang.IllegalArgumentException: "{2}" Conversion Error setting value ''{0}'' for ''{1}''.

Apex report performance is very poor with apex_item.checkbox row selector.

Hi,
I'm working on a report that includes some functionality to be able to select multiple records for further processing.
The report is based on a view that contains a couple of hundred thousand records.
When i make a selection from this view in sqlplus , the performance is acceptable but the apex report based on the same view performes very poorly.
I've noticed that when i omit the apex_item.checkbox from my report query, performance is on par with sqlplus. (factor 10 or so quicker).
Explain plan appears to be the same with or without checkbox function in the select.
My query is:
select apex_item.checkbox(1,tan_id) Select ,
brt_id
, tan_id
, message_id
, conversation_id
, action
, to_acn_code
, information
, brt_created
, tan_created
from (SELECT brt.id brt_id, -- view query
MAX (TAN.id) tan_id,
brt.message_id,
brt.conversation_id,
brt.action,
TAN.to_acn_code,
TAN.information,
brt.created brt_created,
TAN.created tan_created
FROM (SELECT brt_id, id, to_acn_code, information, created
FROM xxcjib_transactions
WHERE tan_type = 'DELIVER' AND status = 'FINISHED') TAN,
xxcjib_berichten brt
WHERE brt.id = TAN.brt_id
GROUP BY brt.id,
brt.message_id,
brt.conversation_id,
brt.action,
TAN.to_acn_code,
TAN.information,
brt.created,
TAN.created)
What could be the reason for the poor performance of the apex report?
And is there another way to select multiple report records without the apex_item.checkbox function?
I'm using apex 3.2 on oracle 10g database.
Thanks,
Niels Ingen Housz

Thanks for your reply.
Unfortunately changing the pagination doesnt make much of a difference in this case.
Without the checkbox the query takes 2 seconds.
With checkbox it takes well over 30 seconds.
The second report region on this page based on another view seems to perform reasonably well with or without the checkbox.
It has about the same number of records but with a different view query.
There are also a couple of filter items in the where clause of the report queries (same for both reports) based on date and acn_code and both reports have a selectlist item displayed in their regions based on a simple lov. These filter items don't seem to be of influence on the performance.
I have also recreated the report on a seperate page without any other page items or where clause and the same thing occurs.
With the checkbox its very very slow (more like 20 times slower).
Without it , the report performs well.
And another thing, when i run the page with debug on i don't see the actual report query:
0.08: show report
0.08: determine column headings
0.08: activate sort
0.08: parse query as: APEX_CMA_ONT
0.09: print column headings
0.09: rows loop: 30 row(s)
and then the region is displayed.
I am using databaselinks in the views b.t.w

Problem with clicking CheckBox eswith eCATT recording

Hi All,
Iam using SAP GUI 640,ECC500.
Am trying to set some default setting in Finance Transaction FB00 with clicking some checkboxes.
So,After i recorded with clicking checkboxes,For testing that recording i unchecked the check boxes manually and executed the script .but i dont see any boxes checked after i execute the script.I checked in the debugging mode,it is showing in the screen that the checkboxes are checked.but at the end of the script when i open the transaction manually the checkboxes are unchecked.
Is their anything to be cautious when recording Checkboxes.If so please pass your comments.
Thanks in Advance,
Sarapu

HI Rajender,
Are you using TCD or SAPGUI for the recording.
In either cases make sure that you are passing value "X" to the checboxes in your recording or passing value "X" to the variable you have assigned to the checkboxes.
In general you donot need to take any special care for handling Check boxes and they are identified with both TCD and SAPGUI as part of the standard eCATTS.
Hope this solves your problem. DO get back to me if you still have the same problem.

How do I add and remove text in a text field with a checkbox?

How do I add and/or remove text in a text field with a checkbox?
this is my script in the text box......
event.value="Hello, this is my narrative. \r\n\nFamily: \r\n\n" + this get.Field("FirstName").value + " " + this.getField("LastName").value + was born on"=this.getField("DOB.value + "\r\n\n + this.getField("drpField").value + "\r\n\n" + this getField("Father").value
The text box looks like this...
Hello, this is my narrative.
FAMILY:
John Smith was born on 08/02/2000
Boby Lou
Jack Smith
I need to add/or remove the father field (Jack Smith) & r/n/n with a check box.
Does anyone know how to do this?

There are multiple errors in your code...
Use this code instead (adjust the name of the check-box):
var msg = "Hello, this is my narrative. \r\n\nFamily: \r\n\n" + this get.Field("FirstName").value + " " + this.getField("LastName").value + was born on" + this.getField("DOB.value) + "\r\n\n" + this.getField("drpField").value;
if (this.getField("FatherCheckBox").value!="Off")
msg += "\r\n\n" + this getField("Father").value;
event.value = msg;

Navigation with rollovers

Hi,
I have the nice task to evalute the Portal of the 9iAS v2.
We have a nice web which should be ported to the Portal.
I have there a nice Navigation Bar with rollovers.
How can I build this navigation? I can use "Page Links" from the items to build a navigation with links.
But I want to use images.
My questions:
1. Are there any build in features to do images with links - rollovers with links
and if not - how can I do this.
2. when I use Page Links I can find the right page just by name - how can I do this when
I have to enter this manually?
thanks a lot,
michael

Here's the bad news - letting a graphics application write the HTML for a production site is not a viable method. The tables produced are completely rigid and will break unexpectedly as you build your page and add content (thereby changing the 'shape' of the original layout plan). Please read this to see why that's the case -
http://www.apptools.com/rants/spans.php
The spans are what create "gaps" unexpectedly as the table tries to maintain its shape. I believe the only way to fix this is to not use that FW HTML at all.

Best approach -Tabs based ADF Tree left side navigation with Dynamic Regions with out UI Shell

Hi,
Somebody can help for the best approach to implement the following requirement.
Req: When the user select the ADF Tree left side navigation menu, each menu will open as multiple tabs(Dynamic Tabs) in right side content area with out UI Shell Template.
I completed the
Step-1: From the Model project, I can able to render ADF Tree in the using view and view links. I can get the adf tree which is having 3 menu items. Each menu item having 2 sub menu's.
I took each menu item as one(1) taskflow, each taskflow will have two(2) fragments.
Total I have 3 task flows as Menu Items and 6 fragments for sub menu's.
Step-2: My question is How do I implement Tab based the ADF tree navigation (left side area to dynamic regions in content area) through dynamic regions? Please provide the steps in view layers.

Than ks for your response.
This is working fine for ADF Tree navigation with dynamic regions if the taskflow having only one fragment. if the taskflow having more than one fragments, this will not work. The following conditions are always satisfies one page fragment of either "employees" or "departments" task flow. If the "employees" task flow have 2 page fragments, it's not work even you pass parameters through routers.
public TaskFlowId getDynamicTaskFlowId() {
if (currentTaskFlowID == null ||
currentTaskFlowID.equalsIgnoreCase(“employees”)) {
return TaskFlowId.parse(employeetaskFlowId);
if (currentTaskFlowID != null &&
currentTaskFlowID.equalsIgnoreCase(“departments”)) {
return TaskFlowId.parse(departmetaskFlowId);
return TaskFlowId.parse(employeetaskFlowId);
My question is "Same use case with Dynamic Tabs" when the user click on any adf tree node.

JTable's Cell navigation with TAB

Dear ALL
I have face one problem in JTable's cell navigation with TAB. The problem as describe bellow.
I have two columns NAME and ADDRESS. Set focus on ADDRESS column's first cell. now if i am press tab key then focus controll comes on second cell which is the ADDRESS column. At the end of row controll comes on first row second column that means focus on ADDRESS column's first cell.
Please give me some hints.
Thanks in advance.
Amit

Your description doesn't make any sense (to me at least) so I don't know what your problem is or what you are asking to be changed.
The normal tab order is Left to Right, Top to Bottom. So if the focus is at the top/left normal tabbing would be:
Row 0, Column 0 (name 0)
Row 0 Column 1 (address 0)
Row 1, Column0 (name 1)
Row 1, Column 1 (address 1)
Row 2, Column 0 (name 2)
Row 2, Column 1 (address 2)
Your question seems to imply that your tab from address to addreass, which doesn't make sense.
"Set focus on ADDRESS column's first cell. now if i am press tab key then focus controll comes on second cell which is the ADDRESS "

What is the purpose of the "Store Presets with Catalog" Checkbox?

I am running Lightroom 4.4 on Windows 7x64. I have heard that under preferences its better to uncheck the box that says "store presets with catalog" because it is better to have the presets not tied to and/or embedded in a specific catalog.
However, I noticed that whether the box is unchecked or checked, the presets are always stored in their own subfolder separate from the catalog. Specifically, if the box is checked the path is: "C: Drive"->Lightroom, if the box is unchecked the path is: "C: Drive"->Users->"username"->AppData->Roaming->Adobe->Lightroom. So the presets are not embedded in the catalog file in either case, they are just stored in subfolders in different places (albeit in one case it seems user specific and in another it seems global).
So what is the real point of the "store presets with catalog" checkbox?

Take a look at these pages for more info:

Add new report with a checkbox form

I’m trying to create a list with check boxes to add “contacts to a event”.
I have my table contacts and events, when I create a event I should invite my contacts. I want to create a list with all my contacts with a checkbox option and populate a new table with all the assistance.
I’m searching but I can’t find info.
I hope you have some time thank you
Rodrigo

You can create a checkbox in your list with APEX_ITEM.CHECKBOX. There are quite a few examples to be found when you google, e.g.
http://www.apex-blog.com/oracle-apex/adding-a-checkbox-to-your-report-apex_item-tutorial-30.html
One time I just created a default tabular form with DELETE functionality, so the checkboxes were already in place. I just created another process instead of the normal MRU process. Went pretty well actually.

Any Security Problems with Navigation with Short URLs?

Hi ,
I want to use Navigation with Short URLs for my users to access the portal. But if the users give that Short URLs to other non-users , will the URL open?
I will give the role for the users only. Non-users will not have particular role.
Are these Navigation with Short URLs are safe to use?
Advise me.

Hi,
The iview have "EveryOne Role" and "Super Admin Role".
The portal will not allow any "anonymous" users, because it needs atleast "EveryOne Role" for the access.
Will this create any problem.
I think the "EveryOne Role" is there for the user, if the iview1 assigned for role1 but still in the permissions of iview1 have the "Everyonerole" , it is allowing user to access this right?
Then I need to remove the EveryOne Role from the permissions.

ALV LIST with few checkboxes fields

Hi everyone,
I want to create an ALV with 2 fields that are checkboxes.
I am succeeding to create an ALV with one checkbox field.
How do we do in order to create an ALV with 2 checkboxes fields using ALV LIST ?
I know that we have to specify in the layout of the ALV the name of the field we want it to be checkbox.
For example :
gs_layout-box_fieldname = 'FLAG'.
But, how do we specify a second checkbox field ?
Thanks.
Regards.

Is it possible to do page navigation with just selectOneRadio choice and without link or command button?
<h:form id="form1" styleClass="form">
 <h:selectOneRadio disabledClass="selectOneRadio_Disabled"
 enabledClass="selectOneRadio_Enabled" id="radio1"
 styleClass="selectOneRadio" layout="pageDirection"
 value="#{Main.selectedValue}"
 valueChangeListener="#{Main.handleRadio1ValueChange}"
 immediate="true" onclick="submit()">
 <f:selectItem itemValue="page1" itemLabel="page1" />
 <f:selectItem itemValue="page2" itemLabel="page2" />
 <f:selectItem itemValue="page3" itemLabel="page3" />
 </h:selectOneRadio>
 
 </h:form>
 public String handleRadio1ValueChange(ValueChangeEvent valueChangedEvent) {
 String s = (String)valueChangedEvent.getNewValue().toString();
 return s;
And faces-config:
<navigation-rule>
 <from-view-id>/main.jsp</from-view-id>
 <navigation-case>
 <from-action>#{Main.handleRadio1ValueChange}</from-action>
 <from-outcome>page1</from-outcome>
 <to-view-id>/page1.jsp</to-view-id>
 </navigation-case>
 </navigation-rule>

I hope u figured out a solution for this post already. But, if not u can try this. It worked for me.
In the change listener method, add these few lines for redirecting the control to required page.
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
facesContext.responseComplete();
HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
try {
response.sendRedirect("abc.jspx");
} catch (Exception e) {
e.printStackTrace();

CS4|5 Exporter - how to make slider with no checkbox?

Hi all,
I can't work out how to make a slider with no checkbox next to it.
Also it is possible to make two fields next to each other?
eg:
M: 15 N: 3
Zac, it would be nice if you mentioned in the Docs that multi choice widgets are a Radio Button pair for < 3 otherwise it's a Drop Down box.

Hi Rallymax,
The slider + checkbox behavior was a problem with the first version of the exporter API in CS4, but in CS5 it has been fixed. The problem was in how the exporter host layer interpreted the parameters specified via the Export Param Suite. So when making presets for your exporter, it would make sense to use CS5, since CS4 has the problematic behavior. I haven't tried this, but bringing those presets from CS5 back to CS4 may solve the problem in CS4.
So far we haven't had any need or request for two editable fields side-by-side.
Sure, I can add that detail to the docs.
Regards,
Zac

ALV Tree with editable checkbox

Hi all,
I have a ALV Tree with editable checkbox (for all the parent & leaf nodes) , as one of the column.On clicking of a button in toolbar , i should get the nodes which are checked in checkbox.
But the problem is i am not able to get the nodes which are checked through checkbox in the PAI of the screen,when the button is clicked.
I tried using
CALL METHOD wf_tree->get_checked_items
 IMPORTING
 et_checked_items = lint_selected_node.
but the return table is not containing any entries , even if check boxes are checked in ALV tree.I tried the GET_CHECKED_ITEMS method in event handler method of AFTER_USER_COMMAND and also CHECKBOX_CHANGE , but no success.
lfs_item_layout-fieldname = 'CHECK'.
lfs_item_layout-class = cl_gui_column_tree=>item_class_checkbox.
lfs_item_layout-editable = 'X'.
lfs_item_layout-CHOSEN = 'X'.
APPEND lfs_item_layout TO lint_item_layout.
CALL METHOD wf_tree->add_node
 EXPORTING
 i_relat_node_key = p_lfs_final_key
 i_relationship = cl_gui_column_tree=>relat_last_child
 i_node_text = l_node_text
 is_outtab_line = p_gfs_final
 is_node_layout = lfs_node
 it_item_layout = lint_item_layout
 IMPORTING
 e_new_node_key = p_loc_qmnum_key.
Friends ,if you can suggest something.
Thanks
Abhijeet

hi ,
i have written below code for registering the CHECKBOX_CHANGE event of CL_GUI_ALV_TREE.
APPEND lfs_event TO lint_events.
 lfs_event-eventid = cl_gui_column_tree=>eventid_CHECKBOX_CHANGE.
APPEND lfs_event TO lint_events.
CALL METHOD wf_tree->set_registered_events
 EXPORTING
 events = lint_events
 EXCEPTIONS
 cntl_error = 1
 cntl_system_error = 2
 illegal_event_combination = 3.
IF sy-subrc EQ 0.
* MESSAGE X208(00) WITH 'ERROR'. "#EC NOTEXT
ENDIF.
 SET HANDLER lo_event_receiver->handle_checkbox_change FOR wf_tree.
* SET HANDLER lo_event_receiver->handle_button_click FOR wf_tree.
 ENDIF.
Also according to below code , i have put a break point in the event handler method of CHECKBOX_CHANGE event , so that control shall come here when check box is checked on ALV tree ...
CLASS lcl_event_receiver DEFINITION.
PUBLIC SECTION.
 METHODS:
* handle_checkbox_change FOR EVENT checkbox_change OF cl_gui_alv_tree,

** others = 2
* IF SY-SUBRC <> 0.
** MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

* ENDIF.
* call method cl_gui_cfw=>dispatch.
 CALL METHOD wf_tree->get_checked_items
 IMPORTING
 et_checked_items = lint_selected_node.
 break abhijeetg.
ENDMETHOD.
ENDCLASS.
So according to you , I should get the control in the break point , but its not happening with this .. any thing missing ???
