When writing an autocomplete textfield on a form that is first visible,
and after an ajax call rendered invisible, the autocomplete textfields
on this form get rendered anyway in the ajax response.
The method "renderAutocompleteHead" in AbstractAutocompleteBehavior gets
executed,
even if the AutoComplete component to which it is attached is not visible
within the
component hierarchy.
Below the snippet of code that solved it for us ...
In the class AbstractAutoCompleteBehavior, a test on the visibility was
added.
public void renderHead(IHeaderResponse response) {
if(this.getComponent().isVisibleInHierarchy()) {
super.renderHead(response);
renderAutocompleteHead(response);
}
}
The error becomes visible in the debug window on the webpage.
There is already a bug report filed within jira, and a demo application is
included to simulate the problem.
