Hi,

Create two buttons at design time lets say buttonA and ButtonB.

Create a context attribute of type "Visibility"(com.sap.ide.webdynpro.uielementdefinitions.Visibility) lets say "Visible"

Bind this attribute to "visible" property of ButtonB

In the DoInit method set the visibility to none , so that its not initially visible

public void wdDoInit()
  {
    //@@begin wdDoInit()
	  wdContext.currentContextElement().setVisible(WDVisibility.NONE);
    //@@end
  }

Create action handler for buttonA

Make the button visible using the following code

wdContext.currentContextElement().setVisible(WDVisibility.VISIBLE);

Hi,

Following is the code to do this

  if(buttonClicked) // this is to check when to create the button, make this variable true when first button is pressed.
	  {
		  IWDButton button = view.createElement(IWDButton.class);
		  IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute("<Your Attribute>");
		  button.bindText(attributeInfo);
		  
	  }

Did you searched the forum?
