Performance replace panel with AjaxLink.
Hi, I have a problem to replace a panel with Ajax, I use a AjaxLink to
replace a panel on the other, as follows.
Component current = this.getParent();
current.replaceWith (editorPanel);
target.add (editorPanel);
The problem I have it because it makes a call undue page builder. Thing I do
not want to happen, first because it fails to receive the parameter that was
receiving that page and second because even if it worked, would unduly
penalize performance.
Does anyone know why this call is made?
A greeting and thanks advanced.

Hello, in this project we are not using unit tests, and I can not add a
breakpoint, but I managed to narrow down the error. The call to the
constructor of the page disappears, commenting javascript call panel markup.

Indeed the page is not repainted, but its constructor is called, How to put a
breakpoint?.

Put a breakpoint and see who calls it. Unless you add the page itself in
the ajax request target the page should not be repainted. But even in this
case its constructor should not be called.

Let's see, I have a page that receives a parameter, and since I do a query
parameter to the database to load a panel, within that panel there is
another panel with a AjaxLink, that when you click I want to be replaced by
another panel, everything works fine, ie the panel is replaced, but in my
traces get a NullPointerException, ie when you update with Ajax, the
AjaxRequestTarget, makes a call to the constructor of the page. received
additional setting that always puts me is "lib", regardless of the initially
received. The problem is that it makes a call to the constructor of the page
internally, I do not want it done. My question is why do it? and if you can
avoid it to.

I don't understand what you meant above.
