wicketShow and wicketHide don't check for existence of element before setting
display
-------------------------------------------------------------------------------------
Key: WICKET-1011
URL: https://issues.apache.org/jira/browse/WICKET-1011
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.2.6
Reporter: Ian Ragsdale
Priority: Minor
If for some reason the element doesn't exist, wicket throws a javascript
exception. This can happen if using an ajaxindicatingfallbacklink in an
element that gets removed.
For instance, if you have a list of items that you want to delete via ajax, and
you have a delete button on each with an indicator, when the item is
successfully deleted, the call to hide the indicator throws an exception. This
seems like it should work without an error, and would be easily avoided with a
simple check that e exists. Something like the following would be really easy:
function wicketHide(id) {
var e=wicketGet(id);
if ( e ) {
e.style.display = "none";
}
}
