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
Fix For: Future
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.
