-Xmx256m

Update eclipse.ini

AspectJ: Warning advice defined has not been applied [Xlint:adviceDidNotMatch]

Friday, November 13th, 2009

In Eclipse and AJDT, you will see the following warning if an advice has not been applied

advice defined in xxxx has not been applied [Xlint:adviceDidNotMatch]	xxx.class...

To remove this, add the @SuppressAjWarnings({“adviceDidNotMatch”}) on your advice methods

For example:

public aspect MyAspect{
  pointcut ...

  @SuppressAjWarnings({"adviceDidNotMatch"})
  Object around(Transactional transactional) : mylMethodExecution(transactional){
    ...
  }
}

jQuery: Drag custom Clone helper with the correct width

Wednesday, November 11th, 2009

Often, when you drag an element with the helper = ‘clone’, you want the clone element width to be equal to the draggable element width. Unfortunately, this works only if the “width” has been set to the draggable element.

The solution, is to create a custom method for the helper like:

$(“.draggableElement”).draggable({
helper: function(){
return $(this).clone().width($(this).width());
},
revert: “invalid”
});
