Confusion with <f:setProperty>
I have inherited some code that does not work and it makes heavy use of
<f:setProperty>. I can find little documentation on this that tells me at a
very
low level what is going on (exactly when setters/getters are called)
If I have an <f:setProperty inside a command link, what does it actually do?
Does it call a getter when the page is rendered (and when), and does it call
a setter when submitted (and when)?:
When would I actually use this, and are there other ways to set/get
properties?
What circumstances would you need to use this (when other options will not
work)?
Have tried to experiment but am having a hard time trying to dig through the
code. Any help would be greatly appreciated. Here is the typical code
below
with <f:setProperty> inside a <t:commandLink>
thanks
<t:commandLink
rendered="#{address.showSaveBtn}"
actionListener="#{address.saveOrUpdateListener}"
action="#{address.mainViewAction}"
id="btnSave"
onmouseover="BtnSaveImg.src='../../images/Save-Button-Blue.gif';
return true;"
onmouseout="BtnSaveImg.src='../../images/Save-Button-Silver.gif'; return
true;"
>
../../images/Save-Button-Silver.gif
<f:setPropertyActionListener
target="#{address.mode}"
value="#{address.mode}" />
<f:setPropertyActionListener
target="#{address.autoMode}"
value="#{address.autoMode}" />
</t:commandLink>
