radio buttons and element not defined error

[gengyue]

Hi,

I am running a report using Cold Fusion. This report is generated by cfloop tag. Depends on the record count of a query, the report will list the data retrieved from the database. each row in the report will have a radio button, so there may be lots of radio buttons in this report. These radio buttons are defined in a form tag. User will select a radio button and then click a submit button to an action page to show more detail information.

The funky thing happens if I select first six or five buttons, I got either "page cannot displayed" or "save a file" window opened. I refreshed page and got error message tells me the radio button "viewReportButt on" is not defined in the form. However, when I select other radio buttons, I got through. All the radio buttons have the same name but with different values.

If I have less radio buttons in the form, no such weird case happens. I tested it. When I have 42 or 46 radio buttons, I got the error.

Can anybody here tell me what's the problem? Thank you very much.

Thank you very much for your reply.

In detail report:

error happends here.

Set form.viewReport button to a default value using cfparam. I'm not sure what could be causing the error, but you should try that to begin with. If that doesn't help, try without cfinput, i.e. using normal input elements.

PS. please use code tags when posting code. Thanks.

Hi,

I tried both way and still get the same error. What puzzles me is that all the radio buttons generated from the same loop. Some radio buttons' values are submitted while some are not with value undefined. I don't know why. Even in undefined error, I got two different scenarioes. One is give me "page cannot display"; if I refresh, I can see the detail error message; the other gives me pop up window to ask me save or open the file, and then I can see 500 internal error.

Please help.

Thanks.

Can you give the rest of the code in the audit report page.

Hmm, either I'm missing something simple or this is a strange problem.

OK, to eliminate the possibility of a problem from the client-side, try this code in your detail report page:

<form name="detailform" action="/Ecoater/AuditReport.cfm" method="post">
	<cfloop index="i" from="1" to="42">
<input type="radio" name="viewReportbutton" value="somevalue<cfoutput>#i#</cfoutput>">
	</cfloop>
</form>
