----------------------------------------------------------------
Key: TAPESTRY-2070
URL: https://issues.apache.org/jira/browse/TAPESTRY-2070
Project: Tapestry
Issue Type: Bug
Components: Annotations
Affects Versions: 4.1.3
Environment: OS : Windows XP. Softwares : Eclipse SDK 3.1.0, MyEclipse
4.0.0, JDK 1.5, JBoss application server. HardWare : 80GB HDD, 2GB RAM
Reporter: kanthimathinathan
Priority: Critical
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;">
<span jwcid="[EMAIL PROTECTED]" id="ognl:listIndex"
value="ognl:checkedList[listIndex]" />
</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 / disabled as expected.
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.
please help me to resolve these issues.
Thanks,
Kanthi.
