lopezc Passing parameter to controller Method not working
Hi,
I was wondering if it is possible to pass parameters to our controller method while in a VF page.
I want to render a component only if the method called returns 'true':
<c:NetworkForm case="{!case}" contact="{!contact}" rendered="{!DisplaySection}">
<apex:param name="sectionName" value="NetworkForm" />
</c:NetworkForm>
And the method is the following:
public Boolean getDisplaySection(){
String sectionName = apexpages.currentpage().getparameters().get('sectionName');
System.debug('SECTION NAME::::::::::' + sectionName); //sectionName is null !!!!
if(listOfCategorySections.size() > 0 && callCategory!=null && sectionName!=null){
List<RF_Section_Map__c> sections = listOfCategorySections.get(calltype+callCategory);
for(RF_Section_Map__c loopSec : sections){
if(sectionName.equalsIgnoreCase(loopSec.Component_Name__c)){
return true;
}
}
}
return false;
}
But the parameter is null in my controller, any ideas?
Thanks in advance.

Just in case if you are rerendering this outputPanel on a user interaction, you will have an issue with what u have. I just had this issue. If you specify rendered attribute on an outputPanel and if you rerender that tag from a user interaction, let's say button click(CommandLink), It would not rerender properly. You will either need to wrap the outputPanel with another outputPanel, or move the rendered attribute to the c:NetworkForm tag. And put an id for the ouside outputPanel and rerender that outputPanel. It seem you can't rerender a tag that has rendered attribute.
