Java / PrimeFaces同步Ajax更新

Question

I am trying to synchronize events on the GUI from my backing bean, in order to measure the actual processing time of a particular ajax update. As ajax is, to my knowledge, being processed asynchronously, I fail to gather the diagnostics data I am looking for. Trying my current idea, what I would need to do is execute the second script after the ajax update has been processed.

{...
  PrimeFaces pf = PrimeFaces.current();
  pf.executeScript("functionStart('columnMapping')");
  pf.ajax().update("contentForm:tv_main");
  pf.executeScript("functionEnd('columnMapping')");
...}

How can I accomplish this?

Cheers, Giagl

Answer 1

You need to put the call to "functionEnd" into the callback function of ajax. The most likely function you want is "onsuccess". Try

pf.ajax().update("contentForm:tv_main").onsuccess(pf.executeScript("functionEnd('columnMapping')"));

However from your sample code it's hard to know what exactly you are trying to do exactly, maybe you can share a little more information on what you are trying to accomplish.
