html:checkbox problem

[Santosh Maskar]

I have "<html:checkbox property="selectedCheckBox" value="msgId"/>" in my JSP

here are the respective getter/setter methods for this

private boolean selectedCheckBox= false;

public boolean isSelectedCheckBox() {
return selectedCheckBox;
}
/**
* @param selectedCheckBox The selectedCheckBox to set.
*/
public void setSelectedCheckBox(boolean selectedCheckBox) {
this.selectedCheckBox = selectedCheckBox;
}

When I try to get the value of checkbox(when used checked from JSP) in my action class It always return fase whether it is checked or unchecked

Can someone help on this.

Change

<html:checkbox property="selectedCheckBox" value="msgId"/>

to

<html:checkbox property="selectedCheckBox" value="true"/>

For a checkbox, the value attribute indicates the value that the property in the ActionForm will be populated with if the box is checked.

I think this is a problem in Struts. One way I know to work around the problem is to get the checkbox value from the request parameter and then use logic in your Java code to check the value of the checkbox property being returned in the parameter and then setting the property of ur checkbox in the bean.

e.g. String checkValue = request.getParameter("[checkBoxProperty]");

if(checkValue.equals(true)){
}

Hi,
Struts have one problem as it will send value to form bean only if the check box is selected. For overcoming this issue,in java script u need to give the value externally.

For exmp.
if(document.forms[0].preselected.checked){
document.forms[0].preselected.value="true";
}else{
document.forms[0].preselected.value="false";
}

Where as preselected is the field in form bean, which we are using with check box name also, like

<html:checkbox property="preselected" value="on"/>

It should work as you expect....
