i want to enable/disable a button on clicking a checkbox in the screen. i am
trying the below code Snippet.
HTML template code snippet
<tr jwcid="@For" source="ognl:lists" index="ognl:listIndex"
value="ognl:listData">
<td align="left">
<form jwcid="@Form" style="margin:0px;padding:0px;">
</form>
</td>
</tr>
Java code snippet
@EventListener(events = "onclick", targets = {"checkbox"})
public void updateComponents(IRequestCycle cycle, BrowserEvent event)
{
cycle.getResponseBuilder().updateComponent("button1");
}
Issue 1: Eventlistener is not called for last checkbox and so button is not
enabled.
Issue 2: on clicking 2nd or subsequent checkboxes in the UI screen, Button
is enabled/disabled as expected. However AJAX requests sent is equivalent to
the no of checkboxes(or rows) in the screen, which cause performance issues.
Note : On clicking 1st checkbox, buttons are enabled/disabled as expected
with just 1 Ajax request.
On further analysis found that problem is with DOJO generated Java scripts
in tapestry 4.1.3, For 4th checkbox, Forms of checkbox 1- 4 are submittted
asynchronously. Please let me know how this could be resolved
Thanks,
Kanthi.
