Hi,

Create one context attribute example "Error Displayed" of boolean type and control your code as below.

public void methodA( )
  {
   
   if(validate==false)
    {
    	wdContext.currentContextElement().setErrorDisplayed(true);
               wdComponentAPI.getMessageManager().reportException("Error",true);	
    }
	
  }

   public void methodB( )
  {
    
    methodA();
 
    if(wdContext.currentContextElement().getErrorDisplayed()==false && validate==false)
    {
    wdComponentAPI.getMessageManager().reportException("Error",true);	
    }
  }

Hi,

you may also use some "real" exceptions in your coding. In your outer method place a try-catch block and throw some meaningful exceptions in your inner and outer method.

In the catch do the reporting of the exceptions.

But keep in mind, exceptions are "costly". If you have just an input check on your context, then it maybe better to create a dedicated method for checking your context and other input before you go to any further method.

Hope that helps a little bit,
