Hi,
<apex:commandButton value="Save" action="!{save}"/>should be rewritten as,
<apex:commandButton value="Save" action="{!save}"/>All Answers
Seems like the pagereference that is being returned is causing problem
Hi,
<apex:commandButton value="Save" action="!{save}"/>should be rewritten as,
<apex:commandButton value="Save" action="{!save}"/>Thanks a lot guys for the replies it really helped.
Can someone explain me why are we using the "!{Save}" or why should we use the " ! " mark what does it signify? and sometime they put the "!" mark in the " {} " and sometimes they put outside the braces ..why do we have the differences and when how it has to be used?
If you have an example of Visualforce code where you see the exclamation mark outside the braces, e.g. "!{ something }", please let us know by clicking the feedback links at the bottom of the HTML version of the topic. It's almost certainly an error.
<open brace><exclaimation mark> ... <close brace>, or {! ... }, is the syntax for a Visualforce expression. Whatever is inside those delimiters will be evaluated by Visualforce. Generally speaking, the contents will be either a variable provided to the page by its controller, a controller method call, or a formula of some sort.
See the appendices in the Visualforce Developer's Guide for some more details, in the Functions and Expressions Operators appendices sections. You can also review the chapters on controllers for more details of accessing variables on a page, or calling controller methods.
Hi,
Alderete_SFDC has explained you everything. Its a syntax that we follow in visualforce.
