When the form attribute of the table taglib is empty (blank), it still tries to
render the table to use javascript in order to submit the pagination and
ordering params.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: DISPL-626
URL: http://jira.codehaus.org/browse/DISPL-626
Project: DisplayTag
Issue Type: Bug
Components: Tag Library
Affects Versions: 1.2
Reporter: Angel Ruiz
Fix For: 1.2
Attachments: HtmlTableWriter.java
In order to add support to the DisplayTag when javascript is disabled I have
used the display tag considering the following premise: if javascript is
enabled I put the form with a value of the corresponding formId and if not I
just live it blank. The result is the following piece of code:
<display:table
name="industrySourceSearchForm.listIndustrySource" export="false"
form="${param.javascript == 'false' ? '' :
'industrySourceSearchForm'}"
requestURI="/action/load/industry-source-search"
requestURIcontext="true"
id="industrySource">
This way I have covered both situation when the javacript is enable and when it
is not. The problem is that the current code of the class
org.displaytag.render.HtmlTableWriter, just checks if the form attribute is
null instead of checking if the form attribute is empty, so at the end in order
to have this working I was forced to rewrite that class. Independently of my
concret use case, which is quite special, I think the code should just check if
the attribute is empty and not only that the attribute is not null.
Plese, attached find the class file with the bug fixed. I have not tried to
check if the same implementation criteria could apply to the way other taglib
attributes are managed.
Cheers.
Angel Ruiz.
