Hello everybody,
In order to accelerate updates of dynamic pages and due to your recommendation,
I changed 3 dynamic pages from updating by WTimer to updating by server push.
I added a signal and a cyclic thread that emits it whenever needed. The 3 pages
(container widgets) connect to the signal in the Ctr.
I use the same method to update the page that I used with the Wtimer.
I don't know why but the application collapse when updating. The collapse is
not consistent and also the errors not.
I implemented exactly like in the simpleChat example:
In the Ctr I wrote: WApplication::instance->enableUpdate();
and also connected to the signal.
In the method that is called by the signal emit I wrote:
lock = WApplication::instance->getUpdateLock();
and then I clear 2 tables and inseret new data to them.
afterwards :
WApplication::instance->triggerUpdate();
The collapse is not when calling triggerUpdate but in the methods between
getting the lock and triggerUpdate.
the errors are different everytime. One of the errors was from CreateDomElement
and another one from WebRender::needUpdate().
What's the problem?
the same methods works fine with the WTimer so I guess the problem is not in
the updating table methods.
I use older version of Wt (2.2.3) - If this bug was fixed, please tell me.
Thank you,
Hadas
