Hi,
thanks for the reply's. I've tried to use the JavaScriptSupport but I can't
seem to get it to do exactly what I want. I've got the following code for
zone 2 (I've set visible="true" for testing purposes, it is supposed to be
"false"):
*
*
*<t:zone t:id="popupZone" id="popupZone" visible="true">*
* <div class="overlay">*
* <div style="float:right"><t:actionlink
t:id="closePopupZone">X</t:actionlink></div>*
* <strong>${selectedCustomer.firstName}
${selectedCustomer.lastName} Saldo: ${selectedCustomer.saldo} </strong>*
* <p>*
* <t:form t:id="transaction">*
* <p>Tekst: <t:textfield t:id="transactionText"
t:value="transaction.text" size="50"/></p>*
* <p>Køb: <t:textfield t:value="transaction.value"
size="10"/></p>*
* <t:submit value="Gem"/>*
* </t:form>*
* </p>*
* </div>*
* <t:trigger event="setFocus"/>*
* </t:zone>*
The "onSetFocus" event looks like this:
* @Log*
* public void onSetFocus() {*
*
*
* //if(selectedCustomer.getFirstName() != null) {*
* javaScriptSupport.autofocus(FieldFocusPriority.OVERRIDE,
"transactionText");*
* //}*
*
*
*
*
* }*
When first loading the page, the "onSetFocus" event is called and the focus
is set to "transactionText" field, as expected. But when submitting the
form in zone 1, which updates zone 2, I get the following error "cannot
call method 'activate' on null" (the "onSetFocus" is called, when updating
zone2).
The problem I actually try to solve, is to set focus on the
"transactionText" field, when zone 2 is updated, so it should not have
focus on initial page load.
