How to get the values from a checkBoxes in a abstract component
Hi,
I am building a page where I have a abstract component that is working on a
list of articles in a form. The user should be able to check/uncheck each
and everyone of the list content with checkboxes. The question is how do I
work with checkboxes in a abstract component? How do I get the value from
the form?
Have anybody done this before?
Thanks,
Jacob

I dont know how to do that...this is how part of my abstract component look
like now:
if (menuItemIdList != null && menuItemIdList.size() > 0) {
writer.begin("ul");
writer.attribute("class", "categories");
for (Long menuItemId : menuItemIdList) {
MenuItemDTO menuItemDTO =
articleLinkDTO.getMenuItemDTOMap().get(menuItemId);
List<Long> articleIdList = menuItemDTO.getArticleIdList();
/* More than one article, generat the links in lvl 2 */
String menuItemName = menuItemDTO.getMenuItem().getName();
writer.begin("li");
writer.attribute("class", "menuItems_lvl_1");
menuNameStr = menuNameStr.replace(" ", "").toLowerCase();
writer.begin("div");
writer.attribute("id", "lvl_1_" + menuItemName);
writer.attribute("class", "subCategory");
writer.begin("a");
writer.attribute("href", "");
writer.begin("span");
writer.print(menuItemName);
writer.end(); // end span
writer.end(); // end a
writer.end(); // end div
if (articleIdList != null && articleIdList.size() > 0) {
writer.begin("ul");
writer.attribute("class", "subMenuItems_lvl_2");
int index = 0;
for (Long articleId : articleIdList) {
Article currentArticle =
articleLinkDTO.getArticleMap().get(articleId);
writer.begin("li");
writer.attribute("class", "lvl_2");
writer.begin("div");
writer.attribute("id", "lvl_2_" + currentArticle.getName());
writer.attribute("class", "from_lvl_2");
/* add the checkbox */
writer.begin("input");
writer.attribute("type", "checkbox");
writer.attribute("name", index);
writer.attribute("value", articleId.toString());
if (currentRepSiteArticleIdSet.contains(articleId)) {
writer.attribute("checked", "true");
}
writer.end(); // end input
/* the link open up the article in a pop up window */
writer.begin("a");
writer.attribute("target", "_blank");
writer.attribute("href", currentArticle.getText());
writer.begin("span");
writer.print(currentArticle.getName());
writer.end(); //end span
writer.end(); // end a
writer.end(); // end div
writer.end(); // end li
index++;
}
writer.end(); // end ul
writer.end(); // end li
}
}
writer.end(); // end ul
}
do you have any pointers on how to generate and retrieve the checkboxes that
would help a lot....
Thanks,
Jacob

During render, have you considered extract the list
from your DTO object and then pass the list to
MultiplePropertySelection ?
During rewind, do the oppose.

Hi Shing,
I have looked in to the MultiplePropertySelection component. They all look
fine, but the problem is that I am working in a Abstract Component because
the DTO object I have in the web layer is a complex structure and I need to
iterate through one list to get the actual list that will contain the
checkboxes...
for () {
for () {
<!-- Here I have the list where I want to use the checkbox
component -->
}
}
Do you have any suggestions on how to solve this in a Abstract Component
way?
Thanks again for all the help,
Jacob

There is an example on
MultiplePropertySelection at
http://lombok.demon.co.uk/tapestry4Demo/app
In case you did not know, in the contributed library,
there are also simliar componets :
CheckboxGroup, ControlCheckbox and ControlledCheckbo

No, but I am looking at it right now,
Have you worked with this component your self? Do you have any example on
how to use it?
Thanks,
Jacob

Have you looked at the source code of
org.apache.tapestry.contrib.form.MultiplePropertySelection
?
MultiplePropertySelection is an abstract form
component that renders its checkbox ?
