Yep.
public final Component setOutputMarkupPlaceholderTag(final boolean outputTag)
{
if (outputTag != getFlag(FLAG_PLACEHOLDER))
{
if (outputTag)
{
setOutputMarkupId(true);
setFlag(FLAG_PLACEHOLDER, true);
}
else
{
setFlag(FLAG_PLACEHOLDER, false);
// I think it's better to not setOutputMarkupId
to false...
// user can do it if we want
}
}
return this;
}
But typing an extra line of code will not necessarily kill you;-)
