Re: Nested tags not working with session-scope form
If you can simply switch nested for html or logic, then the markup isn't specifically made for the nested tags. ie: you've probably used the name attribute etc which the nested tags don't need. If you're able to use html or logic, then you may as well use the original tags. If you want to take advantage of the nested tags, you'll have to look at their specific needs in the documentation, or the tutorials at http://keyboardmonkey.com/next All the best. Arron. Hello, I have a session scope ActionForm. I have a need to use the nested tag library to iterator over some nested beans in the form. However, any use of a nested:text, nested:write, nested:iterate, etc., will not output the properties of the ActionForm. This results in a blank HTML form in my browser. If I changed the nested prefix to the original html, logic, etc. Then everything outputs fine in the HTML. I am wondering if anyone has come across this problem before, and knows what I might be doing wrong or something I can check. To check my sanity, i wrote a simple web app using session-scoped action forms and nested tags, and it worked fine. I just can't figure out why it works in one web-app and not the other.

Re: Nested tags always break
Rick, You still having this problem?... can I see the tag markup that's causing the problems?... If the root tag is picking up the name of a valid bean, and the iterate tag has it's property attribute properly set, then I assure you that you don't need the name attribute in the write tag. I'm hoping that there's more to the iterate tag than just the Id. to get foo[i].bar you'd need... nested:root name=someBean nested:iterate property=foo nested:write property=bar / /nested:write /nested:root I haven't really used the id attribute in struts apps since I built the original tags a couple of years ago. So I'm no absolute authority on whether or not the base tags are managing it correctly or what... :P Arron. PS: Love the nested tags always break subject, too. I have a situation where I can use nested:root name=ac, nested:iterate id=foo, and then *must* use nested:write name=foo property=bar, rather than omitting the name attribute. If I do, I get an exception No getter method for property foo[0].bar of bean ac. Now, this code was working fine, but I made some changes to the bean (I'm using torque). I know it's not (or at least, it shouldn't be) a problem in the beans, becuase of the fact that it works fine if I include the name attribute pointing to the id of the enclosing iterate tag. Also, why is it that I can get the struts-digest posting but can't post to the struts list? -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Nested Tags
The nested tags are simply different. The advantages of using them is not replicated in the JSTL/EL or any other tag system. The nested tags directly extend the Struts html, bean and logic tag library and add the nested context. Because they are different, they have never been on the recommendation list of many developers on this list, but those that do use them think that they're the duck's nuts because it is quicker and easier to develop more complex views. All in all, you'd have to take a look and see if it's a good fit for you personally. Take a walk through the primer here... http://keyboardmonkey.com/next ...if all you want to do is stay in vogue technology, you'll probably turn to the JSTL. Arron. Thank you all, I just wanted to see if there are going to be phased out in favor of something else... like in the case of bean and logic tags in favor of JSTL ones.

RE: Nested Tags
I have a problem using a Tag for the property of another tag. Isn't that possible? Example: tempArray[0] = bean:write name=data property=bean:message key=\column.client.property\/ /; AFAIK, that's a no-no. It will try to evaluate the outer tag before finding the inner one. The code that processes the property property knows nothing about tags, it just takes the text assigned and tries to use that as a property of the bean.

Re: Nested Tags
I think they are great - allows you to 'scope' your tags, and makes iterators easier and recursion possible. And you can develop reusable jsp fragments since the scope is local to the object of interest.

Re: nested tags
The nested tags extend the Struts html and logic tags. So to use an OO analogy, the nested tags is to the logic tags the same way that a Ferrari is to a car. :P Nested tags organise two things. The bean reference (the name attribute), and the property property. The property property is the most important, as it's what gets everything mixed up. You could always have in the original tags... html:text name=myBean property=one.two[1].three(key).prop / ...the above being the translation of a nested bean down, an indexed list and a mapped list. But you have to do this for every tag, and it's very messy. Getting it all to happen quick and easy is another story. The nested tags mean you can simply go... nested:root name=myBean nested:nest property=myBean nested:iterate property=two nested:iterate property=two nested:text property=prop / /nested:iterate /nested:iterate /nested:nest ...and have the complex property property figured out for you. The rest of the logic tags simply allow other logic to happen against the current nested object, like value comparisions etc. If you use nested tags for the html input, the logic tags will also simplify managing around them. When it all comes down to it, the nested tags figure out the name and the property of the current object, and call the super class which is the original Struts html or logic tag and let them do all the grunt work or writing Html etc. The keyboardmonkey site has a walk-through/tutorial on them if you want to start playing. Arron. Nested tags rock whereas logic tags, while perhaps doing the same thing are more cumbersome. Scoping is much more intuitive - instead of having to talk about 'myForm.myContainer.myObject, you can just use nested:iterate and nested:nest to make your code much easier to read. And, since you can write snippets to the more localized scope, they can be reused on multiple pages. And, if that wasn't enough, you can do recursion with nested. See the www.keyboardmonkey.com site for examples, etc. -jeff On Monday, June 9, 2003, at 08:56 PM, Frances Aleah Z. de Guzman wrote: what is the difference between nested tags and html tags? -- Frances Aleah Z.

Re: nested tags
My questions are : 1. Does the nested tag lib require struts to be used ? I have nested-tag.jar and struts.jar in the WEB-INF/lib but the application is not based on struts framework. It is an MVC app but with our own controller servlet and mapping(like struts-config). When I tried, I got this dreaded error : Cannot find message resources under key org.apache.struts.action.MESSAGE' javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:494) This makes me wonder if struts framework is actually needed for nested tags. Any help would be appreciated.. They extend the Struts tags, so to that end they need the struts library on hand to even run. As for a set-up and running Struts app, it would depend on what tag you're using. The above seems a little fuzzy and trying to get a hold of the ApplicationResources.properties messages, which does need the Struts Servlet fired up. While the theory is sound about using beans and properties etc etc, The Struts tags were geared for nothing but Struts apps, so you could be in for anything with regards to implementation problems. It would be easy to get the nested paradigm working without the Struts tags, but they do all the grunt work with regard to making Html etc. 2. I can't do a nested:define in my included JSP as I get a null pointer exception. Main jsp : nested:root name=docs nested:nest property=treeNode nested:iterate property=childCollection jsp:include page=docnode.jsp / /nested:iterate /nested:nest /nested:root docnode.jsp (this recurses): nested:root nested:equal property=showChildren value=true nested:define id=imgState value=open18x16.gif / /nested:equal !-- restof html code-- nested:iterate property=childCollection jsp:include page=docnode.jsp / /nested:iterate /nested:equal /nested:root What am i doing wrong? The nested:define in this case doesn't seem to be related to a bean property. nested:define is about making a variable out of a property which is relative to the current nested object. Struts' original bean:define may be the answer, as the nested tags only care about one thing... nesting (and can't forgive them for that :P ). You may even want to consider a... *cough*... scriptlet to get at the string value.

Re: nested tags
Nested tags rock, as you have to deal with only one level in the heirarchy at a time. I have been running into some problems using nested tag for recursion, though. I thought you might help me out while we are on same subject. My questions are : 1. Does the nested tag lib require struts to be used ? I have nested-tag.jar and struts.jar in the WEB-INF/lib but the application is not based on struts framework. It is an MVC app but with our own controller servlet and mapping(like struts-config). When I tried, I got this dreaded error : Cannot find message resources under key org.apache.struts.action.MESSAGE' javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:494) This makes me wonder if struts framework is actually needed for nested tags. Any help would be appreciated.. 2. I can't do a nested:define in my included JSP as I get a null pointer exception. Main jsp : nested:root name=docs nested:nest property=treeNode nested:iterate property=childCollection jsp:include page=docnode.jsp / /nested:iterate /nested:nest /nested:root docnode.jsp (this recurses): nested:root nested:equal property=showChildren value=true nested:define id=imgState value=open18x16.gif / /nested:equal !-- restof html code-- nested:iterate property=childCollection jsp:include page=docnode.jsp / /nested:iterate /nested:equal /nested:root What am i doing wrong? thanks arvind --- Jeff Kyser [EMAIL PROTECTED] wrote: Nested tags rock whereas logic tags, while perhaps doing the same thing are more cumbersome.

RE: Nested tags and recursion (Arron tree example)
I was trying to visualize/interact with a tree structure using Struts, and looking through the archives I found references to using Nested tags, which at that moment were an extension provided by Arron Bates (http://www.keyboardmonkey.com). As I believe, since Struts 1.1, Nested Tags are part of the main branch (correct if I'm wrong), so there's no further need to use the .jar provided by Arron at his home page: Struts 1.1 rc1 provides the tag libraries for using Nested Tags. You are correct. Nested tags are part of the Struts 1.1 distribution. However, Arron has made some updates to it and they won't be reflected in the Struts distribution until rc2. So, in the meantime, I would recommend getting the jar at http://www.keyboardmonkey.com/downloads/km-nested-v2.03.jar. Simply place the jar file in the same location as your struts jar. The classes in this jar file will then be loaded. That seems to be true, as I've successfully tried Arron's examples with Struts 1.1 rc1... All but the recursive ones. That's why: 1) I'd like to know if Struts 1.1 rc1 provides Nested Tags, and so recursion, and if they work for other people. Yes, and yes. 2) Has somebody tried Arron's tree examples with 1.1 rc1 tags, and worked? Arron reported success with all his tests.

Re: [NESTED-TAGS]Anyone using nested tags with the latest nightly build?
Thanks for the reply: -- IMG Tag - Thanks for the guideline on the use of the property property. I really thought I covered the doc's but I guess that did not jump out at me. Now that I look back, you clearly state it at the top of the API docs. . The original tags on occasion provide options that don't use the name and property attributes. These uses will then fall outside the nested context, and will most likely cause error. To take advantage of these options, markup using the original tag for these cases. My only issue: The release of the nested tags from 1.1b2 let you get away with some nested tag mis-use. My problem with the IMG tag is not present on 1.1b2. My first thought is that if any nested:tags *may* fail without at least *name* or *property* then the tag should indicate so. I will admit that when building many pages, if the tag works and does not complain I move on. It seemed I got different errors with the nested:img tag: Both were solve by replacing with the html:img tag, as you said. javax.servlet.jsp.JspException: No getter method for property of bean taskListForm at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:881) at org.apache.struts.taglib.html.ImgTag.url(ImgTag.java:622) and javax.servlet.jsp.JspException: Object must be of type Map at org.apache.struts.taglib.html.ImgTag.url(ImgTag.java:628) at org.apache.struts.taglib.html.ImgTag.doEndTag(ImgTag.java:410) at org.apache.struts.taglib.nested.html.NestedImgTag.doEndTag(NestedImgTag.java:106) So I guess in summary a message such as: You must have at least one of these properties: -- Radio Tag --- I should say again that the following file works under TC4.0.4/1.1b2 but not with the last nightly and TC4.0.4 *** I use the radio button as in this file: nested:form method=post action=/printInvOnDemandRouter nested:hidden property=forwardToAction / nested:hidden property=invDFullList/ nested:hidden property=invDsortCol/ nested:hidden property=invDsortOrder/ table trhtml:img pageKey=section.separator //td/tr /table jsp:include page=/WEB-INF/printing/table/InvOnDemandParameterTable.jsp flush=true/ table trtd html:img height=1 pageKey=section.separator //td/tr /table jsp:include page=/WEB-INF/printing/table/InvOnDemandFilterTable.jsp flush=true/ /nested:form This first include works: %@ taglib uri=/WEB-INF/struts-nested.tld prefix=nested % %@ taglib uri=/WEB-INF/struts-html.tld prefix=html % nested:root table tr td Customer:/td td nested:text property=custNumber onchange=clearInv()/ /td /tr tr td Invoice:/td td nested:text property=invNumber onchange=clearCust()//td /tr /table /nested:root This the include that gives the compile error in my previous email: %@ taglib uri=/WEB-INF/struts-nested.tld prefix=nested % %@ taglib uri=/WEB-INF/struts-html.tld prefix=html % nested:root table width=660 border=0 cellspacing=0 cellpadding=0 tr td All/td td nested:radio property=status value=%= Integer.toString(ArConstants.TRANSACTION_STATUS_ALL) %//td td Open/td td nested:radio property=status value=%= Integer.toString(ArConstants.TRANSACTION_STATUS_OPEN) %//td /tr /table /nested:root Thanks again Jeff Mychasiw Arron Bates [EMAIL PROTECTED] on 03/07/2003 12:08:10 AM Please respond to Struts Users Mailing List [EMAIL PROTECTED] To:Struts Users Mailing List [EMAIL PROTECTED] cc: Subject:Re: [NESTED-TAGS]Anyone using nested tags with the latest nightly build?

Re: [NESTED-TAGS]Anyone using nested tags with the latest nightly build?
-- IMG Tag - [..cut..] My only issue: The release of the nested tags from 1.1b2 let you get away with some nested tag mis-use [..cut..] The reason why it stopped working in the recent nightly is that the nested tags have been gutted, and remade to allow them more flexible use, including the use of Tomcat 4.1.18 as a servlet container. I've attempted to closely support previous proper use of the nested tags, but I think that trying to support the same level of mis-use would be a very pragmatic target and really hard. As for the errors you're getting the nested tags are having those errors speak from the internals of the tags they extend. They are a _very_ thin wrapper around the original tags, and I'd like them kept that way really. Mandating properties which can and cannot be set would make the job harder of having them adapt to changes in the underlying tags. Mis-use of the tags would always be at your own peril, but this big change has obviously changed the way in which they can be mis-used. So I supose my response is terribly sorry for now, but the internals probably won't change again, but once again mis-use at your own risk. -- Radio Tag --- [..cut..] Nothing outwardly obvious. Thanks for the code snippets, I'll have to get in and do some testing and get back to you. Thanks again.

RE: Nested tags
You can't nest custom tags in the attribute values of custom tags.
If you're using the JSTL, you might consider using Struts-EL, which is a
contrib library in the Struts distribution. If you use that, your
example would look like this:
campaign:list id=campaign
TR bgcolor=#CC
TDcore:out value=${campaign.name}//TD
TDhtml-el:link page=/app/campaign/promo/index.jspPromo
Mgmt/html-el:link/TD
TDhtml-el:checkbox name=retire
value=${campaign.campaignId}//TD

/campaign:list

how. Could someone help me out.
Here is the full block of code. The campaign:list tag is a custom

that iterates and places the bean in the pageContext object.

The code you have presented isn't very clear. Your Action, for example seems to
declare the controlVO1 reference twice -- won't compile.
Are you trying to say that you have a list of objects within the ActionForm? Is it
being placed in the session/request under the key formList -- 'cos that's how you
are trying to retrieve it in the JSP. Why do you have the getAttribute(...) stuff?
Also, what version of Struts are you using?

Re: [Nested Tags] Problem in 1.1b3 ?
We just tried a recent build (feb 8/03) and the problem is the same... :-( Any insight? frustrating note We are using jboss bundled with tomcat 4.0.6. We see the speed increase with newer tomcat and would like to go higher (4.1x) We understand that to move to newer JBoss/Tomcat 4.1x we need a newer struts, due to some class loading issue(A Digester issue? ). When we go to newer struts , nested tags act funny...

RE: [Nested Tags] Frustration..Should this work?
A really subtle problem. Remind me to make this advice available some place else when I'm done (like a mail archive?)... :) Trap one: It sounds like the bean reference is a collection itself. A little more background clarity... The nested tags never actually define references, they simply construct the nested property property for when a tag really needs it, like a nested text tag or whatever. So, with this root tag being the collection, it will actually try and make a property that looks like [0] rather than myProperty[0]. Basically, when BeanUtils tries to apply the property it's having issues. To get around this, have the collection one level down in a really simple bean, and make the bean reference to that. This will kick everything off with a proper name in front of that index value, eg: listProperty[5] All in all, nested properties must have at least one substantial named property. They can't just go this/ against the root bean, as there's no name for BeanUtils to play with, even for children as their evaluation will be .something, the dot on the front assumes a nesting level and it all falls down. Trap two: This is actually because of the first problem. When the child tags are trying to do their thing, they're simply appending to the index. From above you can see that the follow-on for a child will be [5].somethingProperty. Once again, the property is just BeanUtils having an issue. Summary: Just keep in mind that the nested tags are all about managing the property property so BeanUtils can do its thing. We need that meaningful property to start off with. nested:iterate property=somethingMeaningful I'm quite sure that putting a bean around that top collection will make things easier. Using this/ and such is really just a helper for when you need the the object itself in a collection. Without a properly set up parent, it all falls down. On a completely different note... I just want to thank Sri for really putting in some effort to help people get around the nature of the nested tags. When all the list comes down into my email client and there's a nested problem, one from Sri usually follows smartly. The nested tags have an esoteric following (that I know of), no-one on this list goes out the their way to recommend them outside of the old list in lists problem, whatever (I'm curious to see if they even get a mention in any of these spiffy new books... :). They mostly snag new users who haven't had an old die-hard bend their ear about best (not necessarily pragmatic) practices :) It is a fact however, that they can truly make life easier. I can't watch the list as often as I'd like, and it's been a big reassurance than the users have somewhere to turn with issues. Sri's one of the peoples that make this list a great [ot] Impact with wall resource. How many people apologise for a not leading to the answer?... Thanks again Sri. Arron.

Even though I use the nested:form as the root..for this iterate tag I want to tell it to look to an object in page scope instead of the form bean.

As a JSP bean specified by the name attribute. As the property, specified by the property, of the JSP bean specified by the name attribute. I understand that the name is not needed by the nested tags (thats why I use them so much :-) ), but the nested docs simply point to the docs for the standard logic tags.

It is true that I started using them because of lists in lists thing. I used them in combination with ListUtils.LazyList in commons collections and they worked well. One of the biggest things I like about them is that I can replace the countless bean:write name=formBeanName property=xyz/ with nested:write property=xyz / It always seemed odd to me that the html:text was nested but the bean:write needed the name of the form bean.. They make things so easy that I just use them everywhere without even thinking about some of the issues. I have one big question: I seems that everyone is talking JSTL, struts-EL ect.. How does the nested library fit into this? Does JSTL have the power of nested tags? Will there be nested-EL...?

RE: [Nested Tags] Frustration..Should this work?
Thanks for the reply: It is inside a nested form but I am getting these values by setting to page scope. The nested iterate has no problem reading the collection. The problem is the equal and write tag *inside* the iterate. They only work if I change them to their non nested versions and explicitly set an id to read by the *inner* tags. ** Summary of code below ** The first define tag grabs a wrapper object from application scope and gets the internal List and sets it to page scope - This works. The second define tag gets a value from the form bean (using a nested form) and set it to page scope. - This works. The nested:iterate tag gets the collectionCode from page scope. - This Works.

I suspected a problem to be with the iterate since that's what your stack trace suggests. Also, look at Arron's reply to an earlier post (by you, in fact!) http://marc.theaimsgroup.com/?l=struts-userm=103584892423199w=2. He states that the name attribute is ignored. Given that I don't know how the working version works. I trust by works you mean that you are able to display a collection of label values.

RE: Nested Tags situation any light would be appreciated
Your JSP looks ok. The fact that the data is displaying correctly in the first place suggests that the various elements in struts-config are ok as well. That brings us to what happens when the page is submitted. You *should* (as a test) be able to set up an action that does nothing and just forwards back to the same location. Can you describe -- possibly with a code snippet -- what's going on in your action? Does your form-bean do anything in the reset and/or validate methods?

RE: [Nested Tags] Nested vs logic tags..
Just a hunch-- have you tried specifying a 'name' for the nested:iterate tag? The nested tags don't need it, and if it's provided they will ignore it. Why?... because all the tags are working off the same bean structure, and this is defined for us by the form tag. The nested tags will fetch this bean. Because of this, all the nested tags within the form bean don't need the name property to be set.

RE: nested tags - version problem
Hi after some double checking the problem is with our build copying in the old tld for struts 1.1 WebLogic seems to insist that all tags are valid for the application regardless of whether we are using them in our pages. performance Our main master/detail style jounral entry seems to have too many tags now and is very slow in displaying, even on subsequent (compiled) requests. Traces should it to slow down on page display and not business components Our suspect are garbage collection of tags or overhead from the try/catch blocks Any suggestions? :-) Tom Lister * 020 7612 3030 * [EMAIL PROTECTED] -Original Message- From: Arron Bates [mailto:[EMAIL PROTECTED]] Sent: 17 September 2002 15:31 To: Struts Users Mailing List Subject: Re: nested tags - version problem Do you mean the nested_tags_10.jar from my site?...

Re: Nested Tags question
As far as the problem goes concerning setting against valid indices, my code does that simply enough using a check against ArrayList.size() and the index from the request parameter - if the size is too small, I just add new objects - 3 lines of code. This is all in a for loop, which could recurse - presumably what your commons wrapper does. Guess I'll find out. That's pretty much what it does. Only thing is it's tackled at the collection level so that you only need to use the properties which return and set the collection itself. You have to provide one of these to the iterate tags anyways. Means you don't have to manage the collections yourself. It's all of a muchness, so I'll just say it's less to be concerned with on a regular basis as a wrapper :) Arron. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Setting form properties against beans is a Struts thing, not a JSP thing. The property thing is a Bean thin and can be looked up in the JavaBean spec. The example you quote... monkeyTeamAlpha.monkeyWorkers[0].salary ...is a nested property. An invention implemented within Struts (Craig?). Yep, although in Struts 1.1 it is really a commons-beanutils thing because we abstracted out this generally useful code into a separate package. What it basically is, is a string of calls rather than the single property method. Here, it will get a hold of the form bean, get a hold of the bean returned from the monkeyTeamAlphaproperty. On this bean, it will invoke the indexed property monkeyWorkers[0] which will pluck a bean from a collection or index provided, from this last bean it will will get a hold of its salary property, and set the value. At each stage, you also get the benefit of some intelligence that is built in to the underlying PropertyUtils class. For example, the JavaBeans spec defines two ways to define an indexed property -- you can use getter and setter methods that take a value and a subscript, or you can use getter and setter methods that return the entire array. PropertyUtils makes the expression listed above work for either (or even for a property whose value is a java.util.List, which is an extension to the JavaBeans spec). All this boils down to, is that you can compose objects a little cleaner, rather than have truly enormous beans for everything. Having the indexed properties allows for lists and whatever else. The ability for nesting beans has been in Struts for a long time. The nested tags just make it much easier. There's a primer and tutorial for nested beans here... http://www.keyboardmonkey.com/next ...it should take you over creating and using such a construct. Hope this gets you on th path you're after. Another area of useful learning for the future is the JSP Standard Tag Library (JSTL). Although the expression language syntax supported by JSTL is different from the one in Struts, it is well worth learning about -- this expression language will be supported anywhere in a JSP page in JSP 1.3, and (in the mean time) we will likely adapt Struts tags to be able to use it as well.

Re: Nested Tags question
Adam, Back to the old want lists, but no session objects issue. It's a common problem these days. It's hard to get the list model working nicely without knowing how big the list is going to be so that objects can be set against valid indexes. The post you speek of in the archives is that I've made a collections wrapps in the commons project which will wrap collections so that they can expand by definition when the request comes in with indexed or mapped properties. I'm cutting a short tutorial on it (how to make funky complex form models leaving the session object in the closet), should be finished in the next few days. It should help a lot of people. Most people end up with indexed lists, but it's hard to get them working properly on the back end. It's not just a nested tags thing.

Re: Nested Tags question
Hi there, I'll take a look at it this weekend. I don't get your reference to no session objects. As far as the problem goes concerning setting against valid indices, my code does that simply enough using a check against ArrayList.size() and the index from the request parameter - if the size is too small, I just add new objects - 3 lines of code. This is all in a for loop, which could recurse - presumably what your commons wrapper does. Guess I'll find out.

Re: Nested Tags question
Hi folks, I'm going nuts having a very unproductive day here trying to save these nested tags as I mentioned earlier.

I know JSP will automatically save parameters to a javabean with the correctly named getters and setters, but there's obviously a gap in my knowledge because all my attempts to recreate the situation above have failed.

RE: nested tags question
You should be able to do that. In-fact, that's one of the ways to re-use common page presentations. If you do your job write, then your main page is composed of a bunch of includes to render different parts of the result "tree". Be-careful, however, the last time I checked the nested tags only work well in a static include scenario. They don't work well with dynamic includes, which is what you might find you need to do, if you have a lot of conditionals (otherwise, it's very easy to exceed to the 64K method limit). -AP_ http://www.alexparansky.com Java/J2EE Architect/Consultant http://www.myprofiles.com/member/view.do?profileId=127 -Original Message- From: Kousek, Theron [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 11, 2002 2:33 PM To: 'Struts Users Mailing List' Subject: nested tags question Hi folks: I have a few forms that contain the same type of "template"... I want to create a generic template that uses a form bean. This template needs to handle form beans that are at the root level or a form bean that may be nested.

If this is legal, then I will be able to literally plug and play these templates into other screens and will have one common layout repository. thanks, Theron -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: nested tags question
The nested tags as of probably a month and a half ago, the nested tags penetrate dynamic includes. I tried to mail the few (but vocal :) people that were throwing things at me to get it done, you may have been the one that got away. Apologies. Putting up a tutorial on my site tonight to show the potential of true recursion and JSP's to make a tree structure. Trees have never been more fun. :) Arron.

Re: nested tags

Re: Nested Tags - new be
Sanjay, I'm all for some client-side operation, but at some point the server has to find out about it so that it knows how to manage your data model properly. Forget the nesting tags, this problem will get you in whatever your server side solution is. Once the Html is served, the server just doesn't care until it gets the next request. The nested tags just evaluate the model at JSP execution time, just like any other tag, JSP or top-down servlet. If you had to do it without a trip to the server, you will have to gather all the details of the extra rows in some hidden form element, and then process the details on the server when the user finally submits the page. It's possible, but not fun. Not the least of which is the client-side rendering of the page. If you're using IE5+ NS6+ you can just do Html replacements easy enough. The ability is certainly there... but approach with caution. It could quite easily become a nightmare. For example, if a user is adding a whole heap of rows, they think that the data is in there because it's on the screen as they typed it, and simply types in another URL... all the data is lost, never to return. Not even with the back button (because JavaScript objects and state are not cached by the browser). Unless you can be certain that the page will be posted to the server after filling out these new rows, I would steer clear of it all together. Another option is to have a page on a hidden frame send updates to the server. Every time that something changes to the data on the screen, get JavaScript to fire off the hidden frame with the update. Because you're only wanting to send updates, there's no heavy Html having to be generated by the server to be returned, maybe just a yes or no to tell your JavaScript whether the server got any errors etc. Whatever you do... it will change the way you have to code your web interface, and increase your development time. How familiar are you with JavaScript?... This aint no simple mouse-over. :) The monkey example uses the server-side management simply because a lot of puritans out there simply refuse to regard anything with client-side logic. And it's also 100% easier to do and manage. Arron (MonkeyBanana Author :) Sanjay Choudhary wrote: Hi, I am very new to Struts, jsp and html programming.

Re: Nested Tags - new be
Thanks Arron for your comments. I have a group of prog. in my team who claim to know javascript but none of them envisioned what you wrote. None of them wish to use hidden frames. So only choice left is to do the control over server side. It did help me not to go the wrong way.

Can anyone suggest simple alternatives? I am REALLY stuck. Thanks! I would not use bean:message for these cases. It's main purpose to hold internationalized messages and I hardly believe it would be the appropriate structure for sitemap-like data. For these things you should use xml files or databse. Then initialize some beans from these datastores and you can use at least the standrad jsp scripting to access the properties. incze
