Re: how to solve a problem of fetchin' HUGE collection into form
A method that I used for a user to find out his or her employee id was by having a 'search for employee id' link on a page next to a text field where the user is to enter his or her employee id since most employees don't know it. This caused a new window to display, allowing the user to enter in his or her name. They enter their name, hit submit, and in the same new window, the results were displayed. When the user selects one of these, the javascript populates the main browser window (the one that launched the search page) and the new window closes itself. Slava_L [EMAIL PROTECTED] writes: that's quite nice way.. but then i will need to truncate search results if they are too big to be send on client, wont i ? In the above app, if the search resulted in only one record, then that record was used to populate the main browser window, otherwise it displayed all the results (which probably wasn't very wise in retrospect). Perhaps if the results are, say, over 25 records, then you could ask them to be more specific or perhaps make pages for them to select from - such as when you use a search engine on the web and receive a great deal of results - 25 each page or whatnot (and perhaps with a text field to re-do their search since at that point they'd realize that their search wasn't specific enough). An extension to the above method is by using javascript to initiate the first query on the pop-up window, too. If there is only one result then javascript populates the calling window (such as when a user is pretty sure that the street name is correct but wants the system to do a quick check; perhaps feedback could be provided in the status bar). hth, Elizabeth - Original Message - From: Dan Cancro [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Friday, June 21, 2002 10:01 AM Subject: RE: how to solve a problem of fetchin' HUGE collection into form It sounds like you need to replace your drop down box with a link to a search screen.

Re: how to solve a problem of fetchin' HUGE collection into form
Dare I say it... better info design. The most I've had was 500. From the user's point of view, this is not good. The freezing will most likely not be the server side, but your browser slowly rolling over and having a cardiac arrest. :) Take the lower end of 100,000 options. If eack option had only one letter, one byte, the dowload is already 1MB. Take that to an average of say 15 bytes per record up to 300,000 and the result is one impressive drop-down box. Try getting the text that would be rendered into Html, get it into flat Html, and then test it on the browser. I'm quite sure that you'll be changing your mind and making it a free-text field real quick. Arron. On Fri, 2002-06-21 at 10:48, Slava_L wrote: I have a form with several fields.

RE: how to solve a problem of fetchin' HUGE collection into form
You want to put 300k records in a select box!? You havent really thought very hard about this have you? I wouldnt worry about the app freezing for a long time. Its nothing compared to the several days it will take your poor users to scroll through the select box trying to select the street rofl Your best bet is to replace the select box with a popup window that has somewhat more advanced methods for the user to find and select the street name and then write the value back to the form field using javascript. -Original Message- From: Slava_L [mailto:[EMAIL PROTECTED]] Sent: Friday, June 21, 2002 08:49 To: Struts Users Mailing List Subject: how to solve a problem of fetchin' HUGE collection into form I have a form with several fields.
