Data table filtering issue in RichFaces 4

[martind1111]

I am having a bit of an issue with use of data table filtering. I would like to use a rich:dataTable to present some data and would like to perform filtering based on content of one of the columns. My understanding is that I must define the filterValue and filterExpression properties on the filtering column and an h:inputText in the header facet of the column to perform the filtering. I also need to attach a a4j:event to the h:inputText in order for the table to be re-rendered on a blur event. There is one column defined in my table that contains h:selectBooleanCheckbox (which purpose is to select a set of rows in the table). There is a rendering problem when the focus is in the filtering h:inputText and the user clicks on one of the h:selectBooleanCheckbox checkboxes in the table. What happens is that the checkbox gets checked on the mouse click, but the click creates a blur event, which eventually leads to the application re-rendering the table. When the application re-renders the table, the checkbox that was just checked will come back to its original value of being unchecked.

I am not sure how to solve this issue. I thought that maybe I should use keyup event instead of blur, but I can't get the keyup event to work properly. When I use keyup, each character is initially displayed in the h:inputText, but the h:inputText is blanked out when the table is re-rendered and the focus does not stay in the h:inputText component.

In 3.3.3, I would add the sortable, filterBy and filterEvent property to the column and an inputText field would appear at top of column. The table would get re-rendered automatically every time the user pressed a key. I don't know how to implement same type of functionality with RichFaces 4.

I am using RichFaces 4.0.0.Final.

I did more testing and in the case of a keyup, it is not so much that the inputField is blanked out, but it only reports the last characer typed in. For instance, if I type quickly abc, when it re-renders, it will only display a. And the focus is not in the inputText field anymore. If I change the execute and render properties from @this to @all, the behavior is more in line with what I would expect. The focus stays in the inputText field and most characters are echoed in real-time, unless I type too quick, in which case the feedback is delayed. I think there is a problem with the response time. Maybe someone can give me advice on startegies to fix this issue.

And in order to avoid re-rendering of your inputs (which actually causes your problem) - change the render ="tableId" to render="tableId@body". Then header will not be updated.

It works! Thanks! Martin
