Capture selection on orcontainer

Hi,

Is there a way to capture change in an orcontainer?

My problem is I have an orcontainer which have two container and I want to add some Item events on the items on the containers, there is no issue on the first container in the choice but when I switch to the second container all the events are gone even if I switch back to the first container. So I am thinking if it is possible to capture the change in orcontainer so the events can be re initailize again.

e.g of DCT is

<item/>

</container>

<item/>

</container>

It would probably help if you also showed the FormAPI code you're using to register the events and the context in which they are registered (e.g.: outside the init() function, inside the init() function, inside some other function, etc.)

At worst, you could try to use an onReplicantAdded event handler that [re-]registers the item events for the type of 'or' container selected - but I shouldn't think you'd have to do that.

It would be like this.

DCT:

<container name="productType" location="productType" combination="or">
    <container name="productTextArea" location="productTextArea">
            <item name="productDescription" pathid="productDescription">
               <text>
              <default>Textarea</default>
               </text>
             </item>
            <item name="code" pathid="code">
               <select>
                  <option value="show" label="show"/>
                  <option value="hide" label="hide"/>
                </select>
             </item>

     </container>
     <container name="productBullet" location="productTextArea">
           <item name="productDescription" pathid="productDescription">
            <text>
           <default>Bullet</default>
            </text>
            </item>

            <item name="code" pathid="code">
                <select>
                    <option label="show" value="show"/>
                    <option label="hide" value="hide"/>
                </select>
             </item>
       </container>
</container>

Script:

 IWEventRegistry.addFormHandler("onFormInit", init);
 function init(path){
 var itemsTextarea = IWDatacapture.getItem("/productType/productTextArea").getChildren();
 if(itemsTextarea != null){
 for(var i = 0; i<itemsTextarea.length; i++){
 if(itemsTextarea[i].getType()=="select"){
 IWEventRegistry.addItemHandler (itemsTextarea[i].getName(), "onItemChange",itemhandle);
 }
 else if(itemsTextarea[i].getType()=="text"){
 itemsTextarea[i].setReadOnly(true);
 }
 }
 }

 var itemsTextbullet = IWDatacapture.getItem("/productType/productBullet").getChildren();
 if(itemsTextbullet != null){
 for(var i = 0; i<itemsTextarea.length; i++){
 if(itemsTextarea[i].getType()=="select"){
 IWEventRegistry.addItemHandler (itemsTextarea[i].getName(), "onItemChange",itemhandle);
 }
 else if(itemsTextarea[i].getType()=="text"){
 itemsTextarea[i].setReadOnly(true);
 }
 }
 }

 }
 function itemhandle(item){
 alert("HELLO");
 }

On Initialization the text item is set to read only and the itemchange event is working. But once I switch to the other container (productbullet) , the textfield is not setonly and the itemchange event is not triggering anymore.

So I thought if I can capture the evet in the OR container I can initalize the events so I modified the code init and added a OnReplicantAdded at the start of init function

IWEventRegistry.addItemHandler ("/productType","OnReplicantAdded", replicantHandle);

Well if you give up trying to dynamically assign a handler to all items, this would solve your issue in just a few lines:

IWEventRegistry.addItemHandler("/productType/productTextArea/productDescription", "onItemChange", itemhandle);
IWEventRegistry.addItemHandler("/productType/productTextArea/code", "onItemChange", itemhandle);
IWEventRegistry.addItemHandler("/productType/productBullet/productDescription", "onItemChange", itemhandle);
IWEventRegistry.addItemHandler("/productType/productBullet/code", "onItemChange", itemhandle);

Thank you for you answer.

Initially I am assigning event dynamically. By looping through all the children (item), but I encounter the issue I stated. Which I belive is because when the<productbullet> container is not found using getChildren() that is why It doesn't have any events.

I am very much open to suggestion to make it dynamically if you can suggest some methods on how to do it.

Is there any particular reason why you built it to register events dynamically? From the code snippet you posted, that was unnecessary and the lines I posted should be sufficient.
