[jira] Commented: (WICKET-2175) onBeforeRender() set visibility of NavigationToolbar prevents it from showing again

["Leszek Gawron (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-2175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762973#action_12762973 ] 

Leszek Gawron commented on WICKET-2175:
---------------------------------------

This functionality still does not work, 1.5-SS:

	@Override
	protected boolean callOnBeforeRenderIfNotVisible()
	{
		return true;
	}

	/** {@inheritDoc} */
	@Override
	protected void onBeforeRender()
	{
		setVisible(table.getPageCount() > 1);
		super.onBeforeRender();
	}


Once NavigationToolbar is set to invisible onBeforeRender() is never called again (despite callOnBeforeRenderIfNotVisible set to true). Please advise.

> This code in NavigationToolbar:
> 	@Override
> 	protected void onBeforeRender()
> 	{
> 		setVisible(table.getPageCount() > 1);
> 		super.onBeforeRender();
> 	}
> makes impossible to show toolbar after it became hidden when using with Ajax (AjaxNavigationToolbar)
> Possible solution:
>   @Override
>   public boolean isVisible() {
>     return table.getPageCount()>1;
>   }
