Can i get component attribute values inside the component

[Itzik Peretz]

Hi,

I have some components of inputText and i want to use the id or the value of the component as a value to other attribute (see the bold part)

<h:inputText id="bsmDNSSearch" value="${(installConfig.bsmDNSSearchDefined) ? installConfig.bsmDNSSearch : this.value}"
disabled="#{installConfig.doNotInstallSMAsBool}" />

Is it possible? In General how can you reference to the component attributes inside the component?

Thanks,

Itzik

If you build a custom component then this is usually extended from UIComponent class. UIComponent provides a method getAttributes() which gives you a map that represents all your attributes:

Your value won't work because an inputText control's value expression must be an lvalue. That means if you can't place the value of the left-hand side (before the "=") of an assignment statement, it's not valid.

You can obtain (and modify) the values of the core JSF controls on the client's browser using client-side code, since the default HTML renderer converts them into ordinary HTML controls. However, accessing them is a little more complicated that accessing straight HTML, since the id attributes of the generated HTML isn't the exact same value as the id you code on the JSF. The generated HTML ids are composites of the JSF ID plus the IDs of the containers that surround it such as the h:form object.
