extendedDataTable: Header facet render problem in RichFaces 4 -------------------------------------------------------------- Key: RF-12691 URL: https://issues.jboss.org/browse/RF-12691 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-tables Affects Versions: 4.2.3.Final Reporter: Ilia Vassilev Assignee: Brian Leathem Fix For: 4.3.0.CR1 Attachments: screenshots.zip, testapp.zip extendedDataTable header renders OK if entire table or panel that contains it are rendered. if I render just the header row using render="table@header" format, the header row re-renders, but its format is lost (refer to the attached screenshots). Checkbox in column 1 is the trigger for this issue. * Header contains 'select all' checkbox, each data row contains row-level checkbox. * Click on data row will rerender the header row and this is event that causes alignment to go off. * If I rerender the entire table and/or panel, this does not happen, but causes undesirable performance problems when clicking individual rows in succession due to delays from jsf 2 / richfaces 4 render cycles. It looks like the header-only render is trying to do a vertical center of header cell contents while the panel/table render is not, causing the cell contents to slide down vertically in the header cell. This problem occurs in every browser I tested: IE 9, Firefox 16, Firefox 17, and Chrome 23.0
