http://issues.apache.org/bugzilla/show_bug.cgi?id=12189 ------- Additional Comments From [EMAIL PROTECTED] 2005-10-20 21:53 ------- That could work, however adding another field to the form changes the nature of what's generated in the HTML, and I think the input taglib has always been a 1-1 type of library. It could cause difficulty for people iterating over a form at runtime (eg Javascript); it would post either a single (the hidden) or multiple values depending upon the check state, which might be misinterpreted on the server; finally in a situation where there are multiple checkboxes with the same name it would cause all of the off values to be sent with any on values which would require special treatment on the server side. I've had long enough to think about this! I think the real issue is knowing whether this is a redisplay of the form or the initial display. In the case of a redisplay we want to use the information in the request, in the case of an initial display we want to use the default. In comment 2 I suggested using another field in the form (a non checkbox) to indicate whether this was a redisplay or not. The only problem with that is that some fields will possibly be on multiple pages in a sequence of forms so we could be steered wrong. How about this for a solution? We add an "indicator" (or better name) attribute to the form tag, if the request parameter with the name given in indicator is set then we assume this is a redisplay, and use the appropriate default logic on checkboxes in the form. Also we add an indicator attribute to the checkbox tag so that it can be controlled at a closer level (say different parts of the same form appear each time you submit so there is no one indicator to say if the whole form is a redisplay). I think this could work quite nicely; it will be 100% backwards compatible (no changes in generated code) and I think should work for all situations (except where there are only checkboxes in a form in which case you would need to artificially introduce a hidden indicator field).
