You Want To Display The Encrypted Field On Visualforce And You Are Using Component Apex:outputtext. Will It Work For Encrypted Fields?

Answer»

Encrypted custom fields that are embedded in the <APEX:outputText> component display in clear text. The <apex:outputText> component doesn’t RESPECT the View Encrypted Data permission for users. To prevent showing sensitive information to UNAUTHORIZED users, USE the <apex:outputField> tag instead.

Onchange Event Does Not Work With &lt;apex:actionsupport&gt; In Ie9. How To Resolve This Error?

Answer»

If we add the HEADER on Visualforce page then it CREATES lots of problem in IE9. I think there are few java-script LIBRARY loaded by Header of SALESFORCE which makes IE9 compatible. So the best solution is to enable the Header by using “showHeader=true” in Apex page.
