Big performance problem: when using <s:link> or <s:button> with page.xml

[kenneth.zhangsunny77.hotmail.com]

<s:link> or <s:button> will automatically check the View_id's page.xml, and temporary construct the seam components in the page.xml, then call component's @Create and @Destroy method.

For example:

There is a <s:link> at the menu.xhtml:

    <s:link view="/login.xhtml" value="Login"/>

If login.page.xhtml like this:
    <param name="order" value="#{deptList.order}"/>

seam will automatically construct the deptList component, and call it's @Create and @Destroy method.

I find the issue at Seam 2.0.2.SP1 and 2.0.3.CR1.
It's a big performance problem, please resolve it ASAP.

Thanks a lot  and sorry for my bad english.

I have posted the issue on JIRA.

https://jira.jboss.org/jira/browse/JBSEAM-3609

I believe it only creates the component, if it needs to resolve any of the page param values.

If you put

<s:link view="/login.xhtml" value="Login">
   <f:param name="order" value="#{null}" /> <!-- or a suitable default value -->
</s:link>

Then it wont have to create the component because all values are available.

See if that helps...

And that is why you should vote for JBSEAM-2310!

I have been wondering that I clicked on one s:link among menu list, but all components associated with the menu list were instantiated. Now I got it. Thanks a lot for the post. I voted the critical jira https://jira.jboss.org/jira/browse/JBSEAM-2310.
