Thanks for the response Chuck,

This is the rendered HTML

<h2 style="color: #666;">Login</h2>

<hr />

</div>

</div>

<button name="0.5.11.1.3.9"tabindex="3" class="btn btn-primary btn-large" type="submit"><i class="icon-lock" > </i> Login</button>

</div>

</fieldset>

</div>

Warning! _javascript_ must be enabled for proper operation of the Administrator backend. </noscript>

</div>

I am assigning the context.elementID() to the button's name.

When I click on the button the context.elementID() is 0.5.11.1.3.9, which is correct.

But the context.senderID() is 0.5.11.1

This is the URL with the context's ID

http://localhost/cgi-bin/WebObjects/aplicacionbase.woa/-55550/wo/w46py2RT6cjHT2iRyyRib0/0.0.5.11.1

I am not sure Who is the owner of the 0.5.11.1 ID.

Hi List,

I am creating a Component to use <button > HTML tag in my apps.

I am implementing Bootstrap in my WO application and I want to create buttons with icons.

I followed the example in the book Practical WebObjects, chapter 6 that creates a Hyperlink Component.

This is my code based on the book's example:

public class BootstrapSubmitButton extends ERXComponent {
   public BootstrapSubmitButton(WOContext context) {
       super(context);
   }

   @Override
   public void appendToResponse(WOResponse response, WOContext context) {
    String tabindex = stringValueForBinding("tabindex");
    String cssClass = "btn "+stringValueForBinding("class", "");
    String icon = stringValueForBinding("icon");

    response.appendContentString("<button name=\""+context.elementID()+"\"");
    if(tabindex != null){
    response.appendContentString("tabindex=\""+tabindex+"\" ");
    }
    response.appendContentString("class=\""+cssClass+"\" type=\"submit\">");
    if(icon != null){
    response.appendContentString("<i class=\""+stringValueForBinding("icon")+"\" > </i> ");
    }
    response.appendContentString(stringValueForBinding("value"));
    response.appendContentString("</button>");
   }

   @Override
   public boolean synchronizesVariablesWithBindings() {
    return false;
   }

   @Override
   public WOActionResults invokeAction(WORequest request, WOContext context) {
    if(context.elementID().startsWith(context.senderID())){
    return (WOActionResults)valueForBinding("action");
    }
    return null;
   }
}

I just changed a line:

    if(context.elementID().startsWith(context.senderID())){

The example in the book is coded like this:
    if(context.elementID().equals(context.senderID())){

I had to changed it because it was not working, debugging the code I found that the element's ID is never equals to the sender's ID. It sounds logic because they are two different objects.

Why are they different objects? Look at the page content, what matches the senderID()? Your code is saying "if the action is from me, or from any of my children". Is there something else embedded in your button?

I think my change is correct.

Am I right and that's an error in the book's example?

Did I misunderstand the concepts in the book and I am doing something dangerous for my application?

I am pretty sure the book is correct, I don't understand why you are seeing the results that you are seeing.

Chuck
