Why getBodyAsString Method doesn't Work After Upgrading from Confluence 5.6.6 to Confluence 5.7.4

[Patrice Rompas]

In API calls, the following declaration doesn't work anymore after upgrading Confluence from 5.6.6 to 5.7.4:

Page thePage = pageManager.getPage(id);
String theContent = thePage.getBodyAsString();

getBodyAsString() method needs to wrapped in transaction.
Lazy loading of page properties like the body content fails when the constructor of the page object and the lazy loaders are not called within the same transaction.

 The following code should work:

final String curVersionBody = transactionTemplate.execute(new TransactionCallback<String>()
{
@Override
public String doInTransaction()
{ return pageManager.getPage(id).getBodyAsString(); }});
