Cannot check dynamically created Checkbox

Hi,
I cannot check a dynamically created Checkbox which is binded to a dynamically created node.
The same dynamically created Checkbox can be checked when it is binded to a static node.
Any ideas?

Hello MK,
Checkbox UI element`s property "checked" can be binded only to attribute with type "boolean".
If you create attribute inside the node, check whether node contains any node elements.
Could you please post a piece of your code with dynamic attribute and UI element creation?

How to handle dynamically created checkboxes in JSP???

Hello everybody,
In a JSP page I would like to create checkbox dynamically on every
result line (detail line), then check in some of them and finally pass the checked lines to a JSP bean which will handle them on a submit button press.
The problem are:
- how to index every checkbox in jsp result line in jsp page in order to avoid solutions like this:
<input type=checkbox" name="value1">
<input type=checkbox" name="value2">
etc
- how to read every checkbox to find the checked ones
Is there anobody who has any experience from case like this?
Please, help me.
Best regards,
Danny

Hi, first off, no need to determine what has been checked or not. If the checkbox is checked, on the post, the value will be submitted as part of the request. If the checkbox is not checked, it will not be submitted (it's value will be null). Depending on what you need, I have approached this a number of different ways. One way is to name all checkboxes the same name. If you need to distinguish between two rows in the form, then in the value field for the checkbox, use some type of distinguishing factor, for example,
<input type=checkbox name=chkName value="1:abc">
<input type=checkbox name=chkName value="1:def">
Now, you only have to make one call on the Servlet/JSP receiving the form post, request.getParameterValues("chkName") which will return an array of the non-null Strings that were checked.

Operations on dynamically created checkboxes

Hi Experts,
                      In my application I have created 10 check boxes dynamically. All check boxes are for selecting different request types which the user can select. Out of these 10 one check box is for "ALL requests". Now I want that if All Check box is clicked all other checkboxes must be checked. I want to use on toggle action of checkboxes on dynamicaaly created checkboxes Is it possible? Or I have to create checkboxes statically and only then I can use ontoggle action of checkboxes..
Please help me in this regard.

Error While Calling action on dynamically created checkboxes

please help.

Hi,
Check ur application in debuggermode or go to the transaction ST22 and check the error analysis.
The error may be because u have not assign any action for on toggle. It may be because of any node is initialized and using it....

Bind checked value of dynamically created checkboxes to node attruibutes

This is the scenario:
I need to Create n checkboxes(dynamically) based on the n elements present in a node. The values in the node are populated at runtime. i need to bind a boolean attribute in this node to the check boxes that are created.
Any help would be highly appreciated.
Regards,
Immanuel

Hi,
Try the following:
1. Create a node with 0..n cardinality with the following structure
NodeElement
Column1
Column2
Column3
CheckBoxattribute(boolean)
2. In the view, right-click on the root container>Apply Template>Table
3. Select the NodeElement and set the CheckBoxAttribute UI as Checkbox
In this way u can create a Table with checkbox that are loaded as many elements in the Node at run-time
The checkbox value can be set / get using:
wdContext().nodeNodeElement().getNodeElementAt(<selectedRow>).get/setCheckBoxattribute(true/false);
Hope this helps you.

Checking dynamically named checkboxes.

I have a form with checkbox fields "Check1", "Check2",
"Check3, etc. After submit, I want to loop through to find which
are checked. Something like:
cfloop index="1" from="1" to="4"
cfif parameterexists (check#i#)
do stuff
/cfif
/cfloop
Except CF isn't happy with this.
(Yes, I know parameterexists has been deprecated. That's not
the problem.)
Do you do this with "evaluate"? What is the right cfif
command? Help would be appreciated!
thanks!
B.

If you do not go with Dan's suggestion and a single checkbox
name with a
list of values you would use array notation and|or structKey
exists to
work with this type of data.
<cfif structkKeyExists("form","Check" & i)>
<cfoutput>#form["check" & i]#</cfoutput>
</cfif>

Dynamically set checkbox with actionscript

I'm trying to set checkboxes to selected/unselected based on
variables pulled from a database.
Problem is when the script is run is stops at this code
(where cb is the id of a checkbox):
cb.selected = true;
The code compiles fine with no errors or warnings.
Why isn't it possible to set the selected value of checkboxes
through actionscript? Anyone have any ideas or workarounds?
Thanks in advance

Create checkboxes dynamically

Hi all,
how can i create checkboxes in my view dynamically?
Please specify all classes i need...
regards

Hi,
You would basically need to perform the following steps:
1) First get the reference of the ROOTUIELEMENTCONTAINER using get_root_element.
2) Set the desired layout to the container using the obtained reference.
3) Create an instance of the checkbox using the new_checkbox method of class cl_wd_checkbox.
4) Specify the correct layout information to this newly created checkbox.
5) Add the checkbox to the container ui element.
You would have to mandatorily bind 2 properties of the created checkbox:
bind_checked & bind_text.
The state of the checkbox would get saved into the attribute specified by bind_checked
The text to be displayed beside the checkbox would come from the attribute specified by bind_text
Try insert the following coding into your WDDOMODIFYVIEW:
METHOD wddomodifyview.
DATA: lr_container TYPE REF TO cl_wd_uielement_container,
        lr_checkbox TYPE REF TO cl_wd_checkbox,
        lr_node TYPE REF TO if_wd_context_node.
CHECK first_time = abap_true.
lr_container ?= view->get_root_element( ).
cl_wd_matrix_layout=>new_matrix_layout( container = lr_container ).
lr_checkbox = cl_wd_checkbox=>new_checkbox( bind_checked = 'NODE1.ATTR1'
                                              bind_text    = 'NODE1.ATTR2' ).
cl_wd_matrix_head_data=>new_matrix_head_data( element = lr_checkbox ).
lr_container->add_child( the_child = lr_checkbox ).
ENDMETHOD.

How to set a value to a dynamically created node/attribute?

Hi,
I dynamically created attributes using the following method,
IWDNodeInfo cbOptions = wdContext.getNodeInfo().addChild("cbOpt"+count, null, true, true, false, false, false, true, null, null, null);
cbOptions.addAttribute("opt"+critEle.getQuest_Critid(), "ddic:com.sap.dictionary.string");
How do i assign a value to it now, since the node/attribute cannot be accessed via wdcontext?
On a side note, it seems really troublesome if i need to use a checkbox grp(s) dynamically. I actually need to dynamically create a seperate node + attribute for each checkbox grp i have. Is there any better way to do this?
Thanx in advance

Hi
Steps:
1) Create the action click is done statically (you cannot create action dyanmically)
2) binding the action click to checkbox dynamically
code
public static void wdDoModifyView(IPrivateDynamicProgrammingView wdThis, IPrivateDynamicProgrammingView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
     if(firstTime){
                  IWDTransparentContainer con=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
          IWDCheckBox checkBox=(IWDCheckBox)view.createElement(IWDCheckBox.class,"ck");
          IWDAction act=wdThis.wdCreateAction(IPrivateDynamicProgrammingView.WDActionEventHandler.CLICK,"");
          checkBox.setOnToggle(act);
          con.addChild(checkBox);
    //@@end

Is it possible to dynamically create form fields in PDF form?

Hi all,
I would like to dynamically create object like textbox, dropdown list from xml data. For example:
When I receive following xml data:
<field name="Check Box" type="selectbox"/>
<field name="Text Field" type="textbox"/>
I want to generate 2 form fields check box and text field with title "Check Box" and "Text Field" accordingly.
Is it possible to do it in javascript for PDF form?
Thank you and regards,

You cannot dynamically create objects on the fly like that but you can create interpret the XML and create an XDP file (which is the language of the template file) then bring that into Designer and create a PDF from that.

Passing variables from a dynamically created textinput in AS2?

Hey everyone,
I have a contact form in my flash file with name/email/message fields which a user can fill out and then click send, which passes these to a php script which then emails the information that they entered. This works fine when the text inputs are manually placed on the stage and all the information is passed to the php script and emailed to me. I am just updating it so the textinputs are created via AS2 so that I can style them more easily etc. This is fine however when created via script they no longer get passed to my php file. I am creating the textinput using the following code (which works fine):
var my_fmt:TextFormat = new TextFormat();
my_fmt.bold = false;
my_fmt.font = "Arial";
my_fmt.color = inputcol;
contact_form.createTextField("contact_name", getNextHighestDepth(),112.6, 27, 174, 20);
contact_form.contact_name.wordWrap = true;
contact_form.contact_name.multiline = false;
contact_form.contact_name.border = true;
contact_form.contact_name.borderColor = inputcol;
contact_form.contact_name.type = "input";
contact_form.contact_name.setNewTextFormat(my_fmt);
contact_form.contact_name.text = "";
FYI I am creating this outside the movieclip containing the form (called contact_form) and then adding it into that mc specifically because I thought this may be necessary as doing it within the mc itself (using this.createTextField....) didn't work, however both seem to have the same effect.
I am then doing various checks on the input box contents (to make sure it's not empty etc), this also works fine and gives me the relevant error if it is empty so it's accessing it correctly. I then use the following code to submit the variables and check_status checks the success/failure of the php script and alerts the user accordingly:
loadVariables("http://www.makeaportfolio.com/send_email.php?flashmo=" + random(1000), this, "POST");
message_status.text = "sending....";
var interval_id = setInterval(check_status, 400);
This works fine however does not pick up the value of the dynamically created text input (however does pick up all the text inputs that are manually added to the stage). I am rather confused as to why it's not picking this up and am not sure how I set it to do so, i would be immensely grateful if someone could point me in the right direction?
Thanks so much for your help as ever,
Dave

Hi kglad,
I'm sorry but i still don't understand what you mean? They are all text inputs which are defined in AS2 (you can see the code in my first post), the values (inputtext.text) are surely set by the user when they enter information into the input boxes. Accessing these works fine within my flash file, they just don't get passed to my php file. I got round this by manually creating duplicate textinputs on the stage for each dynamically created textinput which are all hidden, then assigning the values of the dynamically created inputs to the manually created inputs before loading the php file. This works fine as it picks up the manually placed inputs as local. I assume it's something to do with the scope of the dynamically created inputs but I cannot work out how you would ensure they would be picked up as even when you explicitly create them within the relevant mc it doesn't pick them up. As I say i've managed to get it working in a rather convoluted way which is good but would be most interested to understand why the other method doesn't work.
Thanks so much for your help,
Dave

Dynamic Table checkbox binding problem

I have a dynamically created table bound to a objectArrayDataProvider where all the columns have a check box. The thing is when I read the values in the objectArray it has the values as I loaded it. If a checkbox is changed in the table the objectArray dosn't get the change. How can I make this happen?
Thanks in advace.

Inventory forecast help - dynamically creating formulas?

Post Author: ddenise
CA Forum: Formula
I am writing a report that reconciles sales orders to inventory - essentially, group sales orders by the scheduled production date, list out all the parts that are needed and forecast the impact on inventory, highlighting any areas where inventory is foretasted to go negative. The results right now look like this:                               Part          In Inventory          Needed         Inventory RemainingOrder Number 567     Product Number 311187          Part Number 8111234          100                  5                  95          Part Number 8111235      Product Number 311189          Part Number 8111234          100                 6                  94
          Part Number 8112235 You can see the problem is that once I calculate "Inventory Remaining", the next instance of part 8111234, should have an "In Inventory" value of 95, NOT 100, but 100 is what is stored in the database. The next time that part number is used, the database value is pulled and 100 is displayed. A running total or summary won't work because they cannot be used on 2nd pass formulas/variables; "Inventory Remaining" is a formula evaluated on the 2nd pass.The result that I NEED to come out would be:                                Part          In Inventory          Needed         Inventory Remaining
Order Number 567
     Product Number 311187
          Part Number 8111234          100                  5                  95
          Part Number 8111235
      Product Number 311189
          Part Number 8111234          95                  6                  89
          Part Number 8112235 So.... I am thinking that I need to create a formula that does the following while records are printed:Check to see if a variable whose name is equal to the part number that is being printed (in this case "8111234") and if it doesn't exist, then create it, setting it's value to what is in the database (in this case "100")Use the variable's current value, subtract the quantity of those parts that are needed for the current record being printed and updated the variable's value to this difference.If the variable does already exisit, then use it's current value to display in the "In Inventory" column and,Use the variable's current value, subtract the quantity of those parts
that are needed for the current record being printed and updated the
variable's value to this difference.What this would do is essentially, dynamically create variables that can be used for display and other evaluation and update the particular variable that is related to the part number that is being printed. Has anyone done anything like this before? I'm sure I'm not the first to encounter this situation. Also, if there are other ways to solve this problem that Crystal can handle, please advice - I cannot seem to find any other solution. Regards,

How-to handle dynamically created AppModules with JUApplication, JUMetaobjectManager

Hi,
I've got a JClient App, where I want to dynamically create AppModules in the Context of the RootAppModule.
How can I best do this??? The problem is that I can't really use the JUMetaObjectManager.createApplicationObject method and hence I can't use PanelBindings.....well I can't use the JClient Framework.
Is there a way to elegantly manage this issue??
Every solution would be very appreciated! thanks.
