Custom component parameters

Hello, I have a movieclip that I want to export as a SWC with
a single parameter.
I have defined that parameter in the 'Component Definition'
panel by specifying an external class holding the parameter,
however when I drag an instance of that component onto the stage in
another document, the parameters panel does not display any
parameters ?
Any ideas ?
Also, do I have to define an external class to define this
parameter or can I define it in timeline code ?

This may help

about components would be available shortly on the adobe
site.

Multiple output-parameters in a custom component

Is it possible to develop a custom component that returns multiple outputs?
I know that I can define multiple tag <output-parameter> in component.xml, but I don't know how the method of my class can return multiple Objects...
Thanks,
Fabio

You can have multiple getters and setters function that will set or return multiple parameters. Each output parameter can be set to a specific function.

Adding Parameters (Inspectable) to a Custom Component?

Hi --
I am attempting to build a custom component just to learn a
little more
about AS 3.0. I can not figure out where / how in my package
declarations I
can "expose" parameters that will be visible to the user in
the Flash IDE
when using my component.
Thanks

Hi Richard ,

Custom component: porting from lc 8.0 to lc 8.2

hello
i developed a java pojo custom component for lc 8.0, essentially it connected to a db and returned a complex object. Now the environment has been upgraded to lc 8.2 . I've loaded my processes (which include my custom component) on the new environment. When i start the process , my component reaches the finally block where i've logged the db connections closing. Immediatly after the system crushes with the following error(i haven't added the whole stack trace because its huge):
2009-04-10 13:11:21,422 WARN [com.arjuna.ats.jta.logging.loggerI18N] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.disallow] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.disallow] Adding multiple last resources is disallowed.

After that jboss get stucked, printing exceptions every 2 minutes, and i need to stop and restart it. I don't see anything wrong with my code: i get the datasource object, i get a coonettin from it, make my queries/updates and finally i close the connection.
googling i've found this might be due to datasource item being local-tx-datasource instead of xa-datasource, but all datasources are of this kind.
Any hint about this problem will be greatly appreciated
thank you in advance
Stefano

hi Steve
thank you for your answer. Unluckly i'm not using mysql but oracle 9i (or 10i i don't know since i'm just a poor programmer). Anyway i did a test : i've bypassed the datasource file , hardcoding the connection parameters in my custom component and it has got executed without problem, then process has crushed again on a query done by some adobe component. there are many adobe sql component instances to read/write from the same schema my compnent uses, so i suppose the problem is inside datasource configuration. There's a datasource sample for oracle too?
I cannot give much details, since the new system has been recently installed and i don't know all info (i think jboss is 4.2 but i'm not sure)
thanks again
regards

Custom component property value handling at run time

I would like to develop simple custom component which has three properties PROP1, PROP2 & RESULT . These parameters are bound to excel sheet cells as follows..
cell A1 connected to PROP1
cell A2 connected to PROP2 and
cell A3 connected to RESULT.
In excel A1 cell has excel formula set as =IF(A2<5,10,0).
Custom component would be simple button display at runtime and on click of the same, I would like to perform following actions in sequence with N number of times.
1. First push any random number to PROP2. (which is simple task, I believe)
2. Pick new value of PROP1 which is changed due to existance of excel formula (+ using dispatchevent I could able to pass value to excel cell A2. But not able to read new value of PROP1+)
3. check new PROP1 value equal to 10. If it is 10 then count it otherwise again push new random value to PROP2.
4. Continue step 1 to 3 till N number of times. and finally
4. Push number of counts for PROP1 value 10 to RESULT parameter.
All the parameters are bindable (getter/setter with [Bindable]) in Flex component application and flex propertysheet application use binding ID to bind with cell address. with binding direction BOTH and SINGLETON
Here is flex function code which triggered at button click.
public function test002():void {
while ( N < 100)
this.PROP2 = Math.round(Math.random()*1000);
dispatchEvent(new PropertyChangeEvent(PropertyChangeEvent.PROPERTY_CHANGE, false, false, PropertyChangeEventKind.UPDATE, "PROP2", null, PROP2, this));
     if (this.PROP1 == 10)
      cnt++;
   this.RESULT = cnt;
My observations are as follows.
- new push of value to PROP2 get reflected to excel A2 when button click event is over, not at the time of while loop process execution.
- Also I observed PROP1 value never changes and it is the value which is recorded just before button click event of component at run time and remain the same till button click event is over.
- Further to this I notice as click event is over, new value of PROP2 reflected in cell A2 and change value (if it passes IF formula of excel ) in A1 as well. Next button click action takes these new A1 and A2 values in consideration and process the function "test002".
I would like to understand possibility of custom component event execution process, which can able to pass as well as read value from component parameters to underlying excel with changes due to excel formula existance. If it is not limitations (If so) what is the set of commands which can be helpful to achieve this. I appreciate if anybody explain typical event execution required in such scenarios with some actionscript code directions.
Thanks

Marton,
I have tried your solution. It works well immediately after xcelsius dashboard get displayed or preview. It does not wait click event to happen. So I modified further by adding one switch ( "switch001" in code piece shown below) to control iteration by click event. That stops running of iteration immediate after dashboard display.
In order to see iteration I have to click twice on button. First click does send "frm" parameter value to excel and excel formula operates. The excel formula result send back to component via SETTER of "frmResult" . But it stops over there. If I click second time the iteration starts for 100 times.
Also I try to export this to PDF. PDF file get generated. If I try to open PDF file it raise error.
My code is attached here.
"frm" is the parameter that sends random number to excel.
"frmResult" parameter receives excel formula output and send it back to component.
"test()" function operate on button click event and set switch001 and then calls "Calc" function for iterations.
MXML code..........
<mx:VBox>
       <mx:TextInput id="frmResultLabel" width="100" />
       <mx:Button label="test..." click="test()"/>
</mx:VBox>
Actionscript code
public var cnt:int;
          public var N:int = 0;
          public var sum:int = 0;
          public var switch001:Boolean = false;
         public function test():void {
               N = 0;
               sum = 0;
               switch001 = true;
          public function Calc():void {
          if (switch001 == true)
            if (N < 100)
                this.frm = Math.round(Math.random() * 1000);
            else if (N == 100) // return the result
                 this.frmResult = sum;
                 // Label component use to display frm and frmResult values at runtime
                 frmResultLabel.text = sum.toString() + ">" + this.frm + ">" + this.frmResult;
             N++;
          [Bindable]
          private var _frm:int;
          private var _frmChanged:Boolean = true;
          [Bindable]
          public function get frm():int
               return _frm;
          public function set frm(value:int):void
               //if (value == null) value = 0;
               if (_frm != value)
                    _frm = value;
                    _frmChanged = true;

Where to create root BOL in custom component - best practice

Hi Experts,
I have created a BOL class to insert values into a ZTable.
I have created a custom component/views for the BOL. Now how will the create method in the BOL will be called. In which method of the component controller or view controller do I create the BOL root..
I want to use the following code.
CALL METHOD SUPER->WD_CREATE_CONTEXT
DATA:
lref_substitute           TYPE REF TO if_bol_bo_property_access,
lv_index                  TYPE i,
lref_bol_entity           TYPE REF TO cl_crm_bol_entity,
lrf_cuco                  TYPE REF TO cl_gs_mcat_mcat_impl,
lref_bol_core             TYPE REF TO cl_crm_bol_core,
lv_object_name            TYPE crmt_ext_obj_name VALUE cl_crm_catego_genil=>gc_ob_schema,
lv_create_param               TYPE crmt_name_value_pair_tab,
lv_number                     TYPE int4 VALUE 1,
lref_new_substitute       TYPE REF TO if_bol_entity_col,
lr_tx                     TYPE REF TO if_bol_transaction_context
lref_bol_core = cl_crm_bol_core=>Get_instance( abap_true ).
lv_object_name = 'ZHRUS_D2'.
TRY.
    CALL METHOD lref_bol_core->root_create
      EXPORTING
        iv_object_name = lv_object_name
        iv_create_param = lv_create_param
        iv_number       = lv_number
      RECEIVING
        rv_result       = lref_new_substitute.
CATCH cx_crm_unsupported_object .
ENDTRY.
CHECK lref_new_substitute IS BOUND.
lref_substitute ?= lref_new_substitute->get_first( ).
CHECK lref_substitute IS BOUND.
me->typed_context->zhrus->collection_wrapper->clear( ).
me->typed_context->zhrus->collection_wrapper->add( iv_entity = lref_substitute ).
I give the code in various methods and it all works fine. But what is the best way to create the root node.
Regards,
Abdullah Ismail

Hi Abdullah,
I use something like this to create a root entity in the BOL Core. In this case, a standard entity: BTOrder.
*- Data dictionary
DATA lr_core         TYPE REF TO cl_crm_bol_core.
DATA lr_fac          TYPE REF TO cl_crm_bol_entity_factory.
DATA lt_params       TYPE crmt_name_value_pair_tab.
DATA lr_ent          TYPE REF TO cl_crm_bol_entity.
FIELD-SYMBOLS <line> TYPE crmt_name_value_pair.
*- Get the core instance and factory
lr_core = cl_crm_bol_core=>get_instance( ).
lr_fac = lr_core->get_entity_factory( 'BTOrder' ).
*- get supported parameters for this object
lt_params = lr_fac->get_parameter_table( ).
*- Set the process Type
READ TABLE lt_params ASSIGNING <line> WITH KEY name = 'PROCESS_TYPE'.
<line>-value = '0010'.
*- Create the BOL entity, based on parameters
lr_ent = lr_fac->create( lt_params ).
lr_ent = lr_ent->get_related_entity( 'BTOrderHeader' ).
*- Lock order
CHECK lr_ent->lock( ) = abap_true.
It is an alternative way. Check if it helps you creating your Z-Object in the BOL root
Kind regards,
Garcia

Can I define a constructor for a Custom Component?

I have a custom component which I instantiate through ActionScript. For the sake of clean code, I would like to be able to assign the variables through the constructor like any other class:
var myComp:CustomComponent = new CustomComponent(arg1, arg2, ...);
However, when I try to write a constructor in the Script block for the component, it gives me a compile error telling me that I have multiple constructors:
//In Script tag//
public function CustomeComponent(arg1, arg2 ...):void { ... }
Are we not able to define constructors for Custom Components?

If this post helps, please mark it as such.
If you create an array variable in your MXML component, and then set it with myVar="[val1, val2, val3]" in the opening tag of your component, then you basically have a constructor in MXML.
You can use the [Bindable] metadata tag in three places:
Before a public class definition.
The [Bindable] metadata tag makes usable as the source of a binding expression all public properties that you defined as variables, and all public properties that are defined by using both a setter and a getter method. In this case, [Bindable] takes no parameters, as the following example shows:
[Bindable]
public class TextAreaFontControl extends TextArea {}
The Flex compiler automatically generates an event named propertyChange, of type PropertyChangeEvent, for all public properties so that the properties can be used as the source of a data binding expression.
If the property value remains the same on a write, Flex does not dispatch the event or update the property, where not the same translates to the following test:
(oldValue !== value)
That means if a property contains a reference to an object, and that reference is modified to reference a different but equivalent object, the binding is triggered. If the property is not modified, but the object that it points to changes internally, the binding is not triggered.
Note: When you use the [Bindable] metadata tag before a public class definition, it only applies to public properties; it does not apply to private or protected properties, or to properties defined in any other namespace. You must insert the [Bindable] metadata tag before a nonpublic property to make it usable as the source for a data binding expression.
Before a public, protected, or private property defined as a variable to make that specific property support binding.
The tag can have the following forms:
[Bindable]
public var foo:String;
The Flex compiler automatically generates an event named propertyChange, of type PropertyChangeEvent, for the property. If the property value remains the same on a write, Flex does not dispatch the event or update the property.
You can also specify the event name, as the following example shows:
[Bindable(event="fooChanged")]
public var foo:String;
In this case, you are responsible for generating and dispatching the event, typically as part of some other method of your class. You can specify a [Bindable] tag that includes the event specification if you want to name the event, even when you already specified the [Bindable] tag at the class level.
Before a public, protected, or private property defined by a getter or setter method.
You must define both a setter and a getter method to use the [Bindable] tag with the property. If you define just a setter method, you create a write-only property that you cannot use as the source of a data-binding expression. If you define just a getter method, you create a read-only property that you can use as the source of a data-binding expression without inserting the [Bindable] metadata tag. This is similar to the way that you can use a variable, defined by using the const keyword, as the source for a data binding expression.
The tag can have the following forms:
As far as binding, you can add the [Bindable] tag before the class declaration to make bindable all public properties defined as variables, and all public properties defined by using both a setter and a getter method.

Creating a custom component is causing a strange scoping issue

I am a fairly new user to Flash and Actionscript, but I have
a fair amount of experience working with C and Java. I'm currently
working with Actionscript 2 in Macromedia Studio 8. I was trying to
create a new component for a project I am working on, and I
followed the tutorial in the help and all testing works while I am
in context of the flash document where I export the component from.
However, I try testing my component in a new blank document and I
get some strange behavior.
I am able to create a component on the stage, and adjust the
properties perfectly fine. However, when I test the file, the
variables for colors go out of scope. That is, the adjustments I
made to the component through the parameters panel, and saw updated
on the stage aren't demonstrated at runtime. The Number variable I
used however is preserved. I did some traces, and it appears that
this is happening because at runtime in the new blank document, the
variables in the onEnterFrame method go out of scope, where they
weren't before.
It seems really strange to me that I should be able to edit
the color on stage but have it revert while it is running. My
intuition says that if it wasn't going to work in the new document,
that it shouldn't work in either case.
Anyway, here is the code for the .as file, I hope I'm just
doing something stupid.

There seems to be a little confusion here. Think of it this way:
A basic UIComponent by itself is not visible; you can add something you can see to it to make a visual custom component. For example, a ComboBox component is a UIComponent with a ComboBox added to it.
The UIComponent is the lightest weight component available from which you can create other components. I use it as the base for custom components that the user cannot see, like a data manager.

Carlos

Clarifications on Custom component in adobe LC

Hi,
I am new to custom component. I just know when a desired result is not provided by stadard activities by adobe lc then we need to create custom components.
1.Could anyone post me a small sample.
2.How to use it in adobe lc as acitivity to get desired result.
3.I have used invoke web services activity to get the result but what is other way to build a custom component.
4.if i have a java class. which accept input parameters and results into some output. How do i use this java class as custom object.
if possible please post study material on this.
thanks in advance

My first bit of advice would be to get the DSC development plugin from Labs. It will make your development and deployment much easier
http://labs.adobe.com/technologies/lcwcdtool/
The official documentation is pretty good around DSCs:
http://help.adobe.com/en_US/livecycle/9.0/programLC/help/index.htm?content=001404.html
I wrote a couple of articles on DSC development ages ago. Its a bit out of date (before the tooling was available) but it may help you with the basics:

Custom component composed of other components

Hello.
I have a form (long, but simple) that is reused a few times across my applicaition. It would be great if I could package it as a JSF component. But I see no obvious way to create an UIComponent composed of other UIComponents.
Are UIComponents really meant to be written from scrach, each parsing it's own request parameters and outputting raw html? Am I missing something?
Thanks.

Thanks for the quick reply, but I'm still stuck...
How do I go about writing a composite custom
component? Instanciating all sub components and
delegating encoding and decoding to each? That's the road I try to take first.
- Construct a SMALL test-bed application to develop your component.
- consider implementing the naming container interface if you add components as children
- consider acquiring "JSF in Action" from Kito Mann, it's the book with most samples for component building
- announce "absences" to your family. It takes longer than you think beforehand ;-)
- If your servlet-container starts up in less than 10 seconds it's better...
I'm afraid to be asking too much, but does anyone
know where can I find an example of this? I'm
currently browsinng the MyFaces code, but so far
whithout much luck....Well the myfaces code is the second best source after JSF in action and then there are a few tutorials on the net... time to surf to google and http://www.jsftutorials.net/
hope this helps

Anybody can make this simple custom component a complied clip!!!?

Hi,
I have a custom component that has this line of code in the
first frame:
trace(this.Num1 + this.Num2);
where:
Num1:is a Number parameter created via component definition
window
Num2:is a Number parameter created via component definition
window
when I convert this component to a compiled clip it dose not
work because the parameters disappear from the parameter panel and
the component inspector parameters.
I have this trace"

anybody can make it work!!!!

Custom Component or Other solution to this problem...

Hello,
In my pages I have a wizard type menu consisting of:
[ prev   curr-title    next ]
The code to build this menu looks like so:
<h:panelGrid
     id="top_flow_navigation"
     columns="3"
     styleClass="wizardNavTable"
     columnClasses="wizardNavColumn_Prev,wizardNavColumn_Curr,wizardNavColumn_Next">
     <h:commandLink
          action="back"
          accesskey="n">
          <h:outputText value="#{messages['flow.user.other.main.heading']}"/>
     </h:commandLink>
     <h:outputText value="#{messages['flow.user.personal.main.heading']}"/>
     <h:commandLink
          action="submit"
          accesskey="n">
          <h:outputText value="#{messages['flow.user.security.main.heading']}"/>
     </h:commandLink>
     <h:outputText value="#{messages['global.button.prev']}"/>
     <h:outputText/>
     <h:outputText value="#{messages['global.button.next']}"/>
</h:panelGrid>This code is currently repeated at the top and bottom of each page, and also on all the pages involved in the wizard.
The only difference in the code on each page is the messages string.
What I would like to know is ...:
(1) how best to solve not repeating myself at the top and bottom of each page.
JSP include would solve this, is there a JSF way?
(2) ...it possible to wrap this code in a jsp tag and pass in the messages binding string as a parameter...I have tried this before but sadly passing #{...} into a tag throws up errors.
Is wrapping this all in a custom JSF component the solution?
Thanks.
JC.

Create a custom component. You may define your own attributes to pass the parameters.
For example:<custom:component messages="blah" />

Help,Help me!   I want to create a custom component

The first, I'm a chinese,my English is very poor.Maybe I make so many mistakes.so
I say sorry for you.
I want to create a custom component so I research the Java.awt.Component .but I don't understand that the class has a method-------dispatchEvent(AWTEvent e).I want to know what invoke this method and when invoke?
thank u

I believe ( believe mind you )
that the method:
public final void dispatchEvent(AWTEvent e)
Dispatches an event to this component or one of its sub components. Calls processEvent before returning for 1.1-style events which have been enabled for
the Component.
Parameters: e - the event
Is used to send an Event message to This component from another
like :
Say you have 'MyComponent1' sending Events to MyComponent2
AWTEvent e = new AWTEvent( blah whatever.......);
MyComponent2.dispatchEvent( e );
and then the Event Handlers on MyComponent2 if any will recieve 'e'
You Probably don't need to modify this behaviour
I assume you are doing something like
public class TestComponent extends Component
private int MySpecialExtraValue;
public TestComponent()
     super(); // like : new Component()
     MySpecialValue = 5; // Just an example
// Override a Method in Component just as an example.
public String getName()
   String S = "I am a Custom Component";
    return S;
//Another override example
public void repaint()
     System.out.println("repaint() was called");
     super.repaint(); // use the original Component Method
     // blah do own stuff
}Override any methods that you need to get the required behaviour that you want...
I hope this is a help........

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableData extends HtmlDataTable {
     public UIRptTableData() {
          setRendererType("tblmaint.rptTableDataRenderer");
     public String getFamily() {
          return "javax.faces.Data";
public class UIRptTableRow extends UIOutput {
     public UIRptTableRow() {
          setRendererType("tblmaint.rptTableRowRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableCol extends UIColumn {
     public UIRptTableCol() {
          setRendererType("tblmaint.rptTableColRenderer");
     public String getFamily() {
          return "javax.faces.Column";
}Here is part of the faces-config file in case you need it.

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">
<f:facet name="header">
<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>
<h:selectBooleanCheckbox
id="checked"
binding="#{RepeaterBean.checked}"/>
<%-- Invisible checkbox for "created" flag --%>
<h:selectBooleanCheckbox
id="created"
binding="#{RepeaterBean.created}"
rendered="false"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Account Id"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="accountId"
binding="#{RepeaterBean.accountId}"
required="true"
size="6"
value="#{customer.accountId}">
</h:inputText>
<h:message for="accountId"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Customer Name"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="name"
required="true"
size="50"
value="#{customer.name}">
</h:inputText>
<h:message for="name"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Symbol"/>
</f:facet>
<h:inputText id="symbol"
required="true"
size="6"
value="#{customer.symbol}">
<f:validateLength
maximum="6"
minimum="2"/>
</h:inputText>
<h:message for="symbol"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Total Sales"/>
</f:facet>
<h:outputText id="totalSales"
value="#{customer.totalSales}">
<f:convertNumber
type="currency"/>
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Commands"/>
</f:facet>
<h:commandButton id="press"
action="#{RepeaterBean.press}"
immediate="true"
value="#{RepeaterBean.pressLabel}"
type="SUBMIT"/>
<h:commandLink id="click"
action="#{RepeaterBean.click}"
immediate="true">
<h:outputText
value="Click"/>
</h:commandLink>
</h:column>
</h:dataTable>
You may have a look at HTML source to prove that dataTable is already what you need:
<table id="myform:table">
<thead>
<tr><th colspan="6" scope="colgroup">Customer List</th></tr>
<tr>
<th scope="col"></th>
<th scope="col">Account Id</th>
<th scope="col">Customer Name</th>
<th scope="col">Symbol</th>
<th scope="col">Total Sales</th>
<th scope="col">Commands</th>
</tr>
</thead>
<tbody>
2.) The second trouble is still unsettled as previously. Right now I have different task at my job, and I can�t continue investigation of this problem.
But when you find smth., please let me know. I�ll be very grateful.

Unable to Edit the View in Custom Component

Hi Experts,
Please help me to resolve this issue !
I am unable to lock the BOL Entity in my custom component using BTAdminH. I have written the below code in the Edit event Handler for Edit Button. The lr_entity->lock( ) condition statement is getting false and it is skipping the "set_view_editable( me )." code statement. Why??
This is code excerpt that I have taken from edit button of the BP_HEAD/AccountViewSet and altered to my component/View
DATA: lr_entity     TYPE REF TO cl_crm_bol_entity,
        lr_controller TYPE REF TO cl_ZVKH8_bspwdcomponent_impl.
TRY.
      lr_controller ?= me->comp_controller.
      lr_entity ?= lr_controller->typed_context->btadminh->collection_wrapper->get_current( ).
IF lr_entity IS BOUND.
IF lr_entity->IS_LOCKED EQ abap_false.
    IF le_entity->IS_CHANGEABLE EQ abap_true.
       IF lr_entity->lock( ) EQ abap_true.
        me->view_group_context->set_view_editable( me ).
       ENDIF.
    ENDIF.
ENDIF.
ENDIF.
and when I directly executed the below code in the Edit event Handler for Edit Button I am receiving the dereferencing NULL value exception. Why in my custom component in many places this happening??
me->view_group_context->set_view_editable( me ).
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: ZL_ZVKH8_DETAILSEF_IMPL=>EH_ONBACK
Thanks,
Bujji

Hi Summit & NishaNC,
Thanks for your responses !
As suggested, I have debugged the code for ->lock( ) method and there are exceptions raised from some methods.
Method GET_LOCK () -> Method GET_ROOT () ->Method GET_PARENT ()
At GET_ROOT( ) method i have received an exception
"Root entity BTAdminH could not be determined" and one more "Entity BTAdminH could not be locked"
Later when I have checked in MODEL Browser, I found that the BOL object "BTAdminH" for my view is an Access object and not the Root Object.
Hence, I have a question? Does the locking can be done only for ROOT Objects?
If this is TRUE then I think this is the major problem with my custom component where even the cross component navigation is also not happening and in many places I am receiving "Dereferencing NULL Value" information.
Also I have gone through some of the Threads and one information that I found from Sumit Mittal
1. An access object is an independent entity, has primary keys of its own.
2. A root object is a special access object that is at the top of the hierarchy based on business rules.
3. A dependent object's primary keys are supplied by access objects and it's lifetime is bound to them. If the parent object is destroyed, the dependent object is also destroyed.
4. Search objects are query objects useful for querying root objects
5. Search result objects - Search objects return the results in the form of a result object together with a relation pointing to the root object.
6. View objects - ?
7. Dynamic search objects - Used in advanced search, supports ranges and operators
Could you please specify in which scenarios we have to go for Access Objects and Root Objects
Thanks,
Bujji
