[richfaces-issues] [JBoss JIRA] Commented: (RF-8244) dataTable built-in filter cause form values to be submitted to different rows.

dataTable built-in filter cause form values to be submitted to different rows. ------------------------------------------------------------------------------ Key: RF-8244 URL: https://jira.jboss.org/jira/browse/RF-8244 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-tables Affects Versions: 3.3.1, 3.3.2.CR1, 3.3.2.GA, 3.3.2.SR1, 3.3.3.BETA1 Reporter: Hugh Nguyen Assignee: Nick Belaevski This is regarding rich:dataTable built-in filtering. The filter requests submit and process the entire form that enclosed the table, including all the form fields inside the table. Besides the issue of inefficiency, this submission cause an obscure bug: The form data of the first row before filtering SOMETIMES get submitted into the first row that appear after the the filtering request is completed. For example, I have an Invoice table like this Invoice No Invoice Amt (filter input) [Z0000013 ] ------------------------------------------------------------------------------------------------ Z000001334 [66.00] Z000001369 [77.00] Z000001373 [88.00] Z000001375 [99.00] Z000001378 [00.00] The filterEvent is set to 'onkeyup' Now, if I type quickly add '78' to the filter input, the table will show only invoice Z000001378, which is expected, but the Invoice Amt for Z000001378 would become 66.00, which is the value for Z000001334. The value is not just the screen value, but it's also set into the backing bean for Z000001378. Furthermore, the backing bean value for Invoice Amt of Z000001373 is also updated 66.00. I suspect that this is because Z000001373 would be the first invoice shown after the first key stroke ('7') ------------------------- Edit note: I realised that my original example is not quite valid. I rewrote above it with the actual data from my system this time. The notable change here is that each filter key stroke would cause the table to be updated. ------------------------- If I leave filterEvent value as default 'onblur', the bug is less likely to occur, but still can happen if I manage to cause the Ajax requests to be sent fast enough. For Richfaces configuration, I enabled the global queue in web.xml. With a bit of tracing, I found that all the input field values present in the table before the filtering happen is sent along with the Filter input during the enclosing form submission, and there is no ajaxSingle attribute for the Filter input. I guess that there is some mix up of processing the multiple filter requests that come before the filtered result is returned, and this cause the submission value to go into the wrong row(s). My suggestion is that there should be some way to cause the form to only process the Filter input, all other inputs should be ignored, in a manner similar to ajaxSingle attribute for the components that support it.
