Hi Brown,
I've never used isTransparentResolver but I know it was removed in
wicket 1.5 because it was it was quite confusing for users:
http://apache-wicket.1842946.n4.nabble.com/remove-MarkupContainer-isTransparentResolver-td1909586.html
You can try to replace it using one of the solutions described here:
https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-MarkupContainer.isTransparentResolver%2528%2529removed
I am shooting in the dark but I thought I would post the error I am
getting.
I get this error. "Cannot modify component hierarchy after render phase
has started". The full stack trace is at the bottom of this post.
During the form submission process (user clicks on link) then I get the
error above but ONLY when I have a dynamic component with
isTransparentResolver = true.
If I restructure my hierarchy such that transparentResolver is false
then I don't get the same error. Why do you think I get the error?
...
final WebMarkupContainer container = new WebMarkupContainer(
"container" ) {
public boolean isTransparentResolver() {
return false; // true causes error
}
@Override
public boolean isVisible() {
return logic();
}
};

version cant change then anymore)
