The LiveGrid class allows to specify text and select filters for each column so that the displayed rows of the grid can be limited to several conditions that have to match at the same time. For checkboxes (i.e. the Rico.TableColumn.checkbox control) this does not exactly apply.

However, the space could be used for special controls that operate as "check all" and "uncheck all" for the visible checkboxes in that particular column. This patch adds a possibility to create custom filter controls for columns, e.g. plus and minus signs for checkbox columns.

This patch allows developers to specify more complex filters than simple equality or LIKE filters. This opens room for filters that make utilise set relations such as "fieldvalue IN (?)". The question mark is replaced in the backend ricoXmlResponse.php by the filter value supplied by the Rico.Buffer.AjaxSQL.

This patch adds back the possibility to display HTML code in LiveGrid columns that broke in Firefox 20.x. Before this one could return HTML code such as <img src="...something"> that was parsed as proper image tag.

The behaviour of the XML parser in XmlHttpRequest has changed. This breaks display of HTML elements returned by AJAX/SQL backends.

The behaviour differs from other browsers and older versions of the same browser. It is possible that it'll be changed back in Firefox 21.x and higher.

This breaks Icons and other HTML code in Rico.LiveGrid cells

This patch has been rejected upstream - since the fix should be applied to Firefox instead.

This patch fixes a problem with with regards to select filters.

When the filter value is stored in a cookie the filter is automatically reapplied on page reload. If table values have changed in the meantime so that the original filter value is not available anymore the LiveGrid will display 0 rows and the select filter element will display __ALL__ (since the value it is set to is not available).

The problem could be resolved by filtering for a different value and then resetting the filter select element back to __ALL__. However, since the filter already displays __ALL__ most users won't notice that the grid is already filtered.
