ajax components rendering behavior
Hi !
I have 2 components on a page : a chart (A) and a form containing details
about the chart (B).
They both communicate through ajax.
On pressing a link on A , B gets filled in with the details.
On submiting the form (B) , A gets refreshed(a new chart is generated
reflecting the modifications from the form).
Pressing the link on A is infact calling
tapestry.linkOnClick('
http://localhost:8080/MyPage,B.sdirect?updateParts=B&objectId=732921506','B',false)
};
I see that along with the initialization script of B is also called the
initialization script of A.
Also , the A gets rerendered : methods like pageBeginRender ,
prepareForRender (in which i'm doing the generation of the chart) are called
on component A.
The re execution of script is not of so much trouble as the rerendering of
component A ( since the chart is regenerated, even is not needed to be
refreshed).
Is this the expected behavior or i'm doing something wrong ?
Thanks,
Alex

Perhaps not the best solution but it works :
I added a flag in an ASO object which controls whether that piece of code
i'm interested in should be executed or not.
Cheers ,
Alex

I think it's normal because in case of your ajax request the entire page
is rendered on the server, although just some parts of it are refreshed
on the client.
Shoot me if I'm wrong :)

The script of A is called because is executed in the prepareForRender
method.
So , i rephrase my question to : Is it the normal behavior that the method
prepareForRender of component A (the calling component) is called when B is
requested to refresh ?
Thanks a lot !
