Iam trying to render a document as pdf , & created a VF page but when its displaying data on the page its showing date with the time

Is there a way to have custom buttons only appear, or even be disabled, if certain criteria is not met? For example, if Widget__c is blank or missing in an object, do not show or disable a custom button named 'Transform Widget'?

Any help is greatly appreciated.

Is it possible to call methods dynamically?  Something similar to call_user_func() for PHP, or even eval() for all I care at this point.

Any suggestions?

Is it possible to iterate over a List of Maps? In the simplest form, a Map<String,String>... I want to be able to do the following in a visual force page (simplified):

VisualForce Page

<apex:repeat value="{!customMap}" var="map">
{!map.name} : {!map.custom}

</apex:repeat>

Controller

public someController
{
public List<Map<String,String>> customMap = null;

public getCustomMap()
{
if (customMap == null)
{
customMap = new List<Map<String,String>>();

customMap.add(new Map<String,String>{
'name' => 'Apple',
'custom' => 'Pie'
});

customMap.add(new Map<String,String>{
'name' => 'Banana',
'custom' => 'Cake'
});
}
return customMap;
}
}

 Would hopefully print something like...

Apple : Pie
Banana : Cake
