No, it doesn't work also. I get the same exception everytime.
I want to have the possibility to select multiple folders, so I did
what you suggested: added property selectedFolders of type String[], so
I added this code to my ModulePathForm:
private String[] selectedFolders;
public String getSelectedFolders(int index) {
return this.selectedFolders[index];
}
public String[] getSelectedFolders() {
return this.selectedFolders;
}
public void setSelectedFolders(int index, String selectedFolders) {
this.selectedFolders[index] = selectedFolders;
}
public void setSelectedFolders(String[] selectedFolders) {
this.selectedFolders = selectedFolders;
}
and the jsp page looks the same as you wrote:
<html:select property="selectedFolders" multiple="true">
<html:options property="folders"/>
</html:select>
I really don't know where is the problem. Really appreciate any other
hints.
Thanks,
Martin
