Repopulation is a freebie under normal circumstances. Using JavaScript to manipulate a form (at least to the extreme of changing the entire number of elements on the form etc.) is not normal circumstances.
How about your JavaScript will work under normal circumstances but, wait, if a user turns off JavaScript then your app will be almost useless. There's definitely variables to every equation. -----Original Message----- From: Sashi Ravipati [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2003 11:35 AM To: [EMAIL PROTECTED] Subject: RE: How to repopulate Form which has html elementswithsamename This is a small example I started off, but in my actual application I have Six columns what are enterable with a combination of List boxes and text boxes. I am still not sure as how this works. Struts says repopulation is a Freebie, but looks like it is not in my case. I am struggling to understand the code snippet u sent, hope I will come out success full >>> [EMAIL PROTECTED] 06/06/03 11:17AM >>> I can't think of anything special. But actually, I don't think it makes it into your action if validation fails anyway. I can see many little problems with doing what you need to do. What if nothing is entered for one element and not the other? I think the arrays would be off... This gets you started but I would guess that you should use a hidden field for the name along with a <bean:write> so that they won't submit a blank name and make your arrays off. This is for within the iterate tag only of course. For the select you shouldn't have to worry about null so you could leave that as is. Have a remove button next to each one on the error page (since they can't edit the name if you do a hidden field). Are you sure you don't want to just punt? :-) -----Original Message----- From: Sashi Ravipati [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2003 11:19 AM To: [EMAIL PROTECTED] Subject: RE: How to repopulate Form which has html elementswithsamename Thanks for the code, this will help to start off, Should I do any thing in the ActionForm .

[mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2003 11:02 AM To: 'Struts Users Mailing List' Subject: RE: How to repopulate Form which has html elementswithsamename I think I missed your original code example. With iterate tags when I saw the dashed lines I thought it was your email footer printing out below. Sorry. I think the Ray is right then. If you are going to do things that are outside the norm of standard HTML (like JavaScript) then you will have to use the same way to get out of it. Some other posts suggest logic iterate. I guess that would work. You would have to do something like: <TABLE id="mytable"> <!-- Do a present check in case you are coming into this form for the first time. Write out the ones already submitted --> <logic:present property="firstName"> <bean:define id="sexArray" ... /> <logic:iterate id="currPerson" property="firstName" indexId="curr" > <% String currSex = sexArray[curr.intValue()]; %> <TR> <TD> <html:text name="sex" value="<%=Util.getDisplayNameFromId(currSex)%>" /> </TD> <td><html:text property="firstName" value="currPerson" /></td> </TR> </logic:iterate> </logic:present> <TR> <TD> <html:select property="sex"> <html:option value="MALE">Male</html:option> <html:option value="FEMALE">Female</html:option> </html:select> </TD> <td><html:text property="firstName" /></td> </tr> </TABLE> -----Original Message----- From: Sashi Ravipati [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2003 10:31 AM To: [EMAIL PROTECTED] Subject: RE: How to repopulate Form which has html elementswithsamename Shane Sorry for all the confusion and please bear with me.. How do I get Struts to repopulate multiple elements with all with the same property? this is my exact problem.. Let me give u my .jsp page example (Initiall the table will have one row) <TABLE id="mytable"> <TR> <TD> <html:select property="sex"> <html:option value="MALE">Male</html:option> <html:option value="FEMALE">Female</html:option> </html:select> </TD> <td><html:text property="firstName" /></td> </tr> </TABLE> I have a Javascript which adds rows to the table on click of a button. So if user has enetered five rows of data then How do I get Struts to repopulate the table? Hope i am clear. Thanks >>> [EMAIL PROTECTED] 06/06/03 10:08AM >>> Then the original question from the start and asked 3 times in an hour because it wasn't answered should have been a one liner: How do I get Struts to repopulate multiple elements with all with the same property? Or something like that. >From your question you say you have a (single) table with a (single) html:text and a (single) html:select. Now you show the code and it is a more clear that you don't have what you mentioned. You should have posted a code example in the first place. It would save time. Now, what doesn't make sense is the same key for the bean:message. This is because I have an interesting solution I am thinking about but if I knew the real way you intend to use the tags believe I could help better. I can't picture the need for this on a form: Name [ ] Name [ ] Name [ ] Then if you say, it is really key="du.theName1" and the next one is "du.theName2" then that wouldn't be truly dynamic. -----Original Message----- From: Sashi Ravipati [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2003 8:26 AM To: [EMAIL PROTECTED] Subject: RE: How to repopulate Form which has html elementswithsamename Thanks for the sample and I have that working. But my issues is slightly different where there are Multiple HTML elements with the same name Eg: <bean:message key="du.theName" /><html:text property="name" /> <bean:message key="du.theName" /><html:text property="name" /> <bean:message key="du.theName" /><html:text property="name" /> <bean:message key="du.theName" /><html:text property="name" /> Then in this case how do u repopulate the page.
