Indexed Properties
Hi group,
I'm using Struts 1.2.4 w/ Tomcat 5.5.4. I'm designing a page that contains a
grid of cells, like an Excel sheet.
In the grid, there are a couple of cells, which could textboxes.
In the JSP, I put the following tags.
<table>
<tr>
<td>
<html:select property="project[0]">
<html:option value="a">0-19</html:option>
<html:option value="b">20-49</html:option>
<html:option value="c">50-</html:option>
</html:select>
</td>
<td><html:text property="hour[0][0]"/></td>
</tr>
<tr>
<td>
<html:select property="project[1]">
<html:option value="a">0-19</html:option>
<html:option value="b">20-49</html:option>
<html:option value="c">50-</html:option>
</html:select>
</td>
<td><html:text property="hour[1][0]"/></td>
</tr>
</table>
This is just an example. I want to have a project[] array and a hour[][] array
to contain necessary information so that in the backend, I only need to
process arrays instead of something like project0, project1, hour00, hour10.
I tried to put something as follows in the ActionForm, but no luck.
private String[] project = new String[2];
private double[][] hour = new double[2][2];
public double getHour(int i, int j) {
return this.hour[i][j];
}
public void setHour(int i, int j, double hour) {
this.hour[i][j] = hour;
}
public String getProject(int i) {
return this.project[i];
}
public void setProject(int i, String project) {
this.project[i] = project;
}
I googled some examples but they are for Struts 1.1. Your help would be
appreciated. Thanks.
Peter

Using the nested version of tags rather than html and logic worked for me.
See http://www.keyboardmonkey.com/next/index.jsp, they have some examples
and the normal Struts how-tos.

This one works fine now.

hour[i][j] does not work.
How to make a 2-dimensional array work with Struts? Thanks in advance!
