Submitting a value from a Form
I have a form that contains a invisible textfield. I set the value of the
textfield, and when i submited the form the value of the textfield should be
submited with it. Here is my code. The ${transactionQuote.XXX} contains the
value of the object. If you scroll down, you can see a form and in that form
i set the value to the textfield using
t:value="${transactionQuote.pickupQuoteID}". Now when i submit the form i
want the value in the textfield to be submitted with it. But the value seems
to be written but not read ? What am i doing wrong ?
${message:date-sent}
${transactionQuote.dateOfTransaction}
${message:recipient}
${transactionQuote.recipientName}
${message:amount}
${transactionQuote.transactionAmount}
${message:unique-id}
${transactionQuote.transactionId}
${message:sender}
${transactionQuote.senderName}
${message:location}
${transactionQuote.senderCountry}
<t:form t:id="processQuoteForm" t:zone="searchTransactionZone">
<div style="visibility: hidden; display:inline;">
<input t:type="textField" t:id="dispenseCashForQuoteID"
t:value="${transactionQuote.pickupQuoteID}"
t:validate="required,minlength=5" class="txtFld"
style="display:block;" />
</div>
<p class="transaction-chk"><input name="confirm" type="checkbox"
value="" /> Confirm recipient's identity by reviewing ID </p>
<p class="transaction-Fld" style="margin:0 auto; width: 360px;">
<label>Phone Number </label>
<input t:type="textField" t:id="dispenseCashForTelephoneNumber"
t:validate="required,minlength=5" class="txtFld"
style="display:block;" />
<label>Confirm Code </label>
<input t:type="textField" t:id="dispenseCashForTransactionID"
class="txtFld" style="display:block;"/>
</p>
<input type="submit" value="Dispense Cash" class="search-btn" />
</t:form>

The problem here is exactly what the error says: transactionQuote is null at
the moment he's trying to set pickupQuoteID.
The submit event is a new request so non persisted fields are gone... I'm
not sure what you are trying to achieve here, but I think you need to use
the context parameter of the Form component or the pages activation context
to load transactionQuote again before it tries to set one of its properties.

I get this error when submiiting the form
Failure writing parameter 'value' of component
remittance/Teller:dispensecashforquoteid: Property 'transactionQuote'
(within property expression 'transactionQuote.pickupQuoteID', of
com.coinfling.web.pages.remittance.Teller@2dfc48fc) is null.

More precisely, never use ${} in attributes that are component parameters.
For example, a <a t:type="PageLink" class="${pageLinkCssClass}"
context="transactionQuote.pickupQuoteID">..</a> is perfectly fine, because
'class' is not a parameter. On the other hand, for 'context', which is a
parameter, using ${} is 100% of the times wrong or useless.

<t:form t:id="processQuoteForm">
<input t:type="textField" t:id="dispenseCashForQuoteID"
t:value="transactionQuote.pickupQuoteID" />
<p class="transaction-chk"><input name="confirm" type="checkbox"
value="" /> Confirm recipient's identity by reviewing ID </p>
<p class="transaction-Fld" style="margin:0 auto; width: 360px;">
<label>Confirm Code </label>
<input t:type="textField" t:id="dispenseCashForTransactionID"
class="txtFld" style="display:block;"/>
</p>
<input type="submit" value="Dispense Cash" class="search-btn" />
</t:form>
I have done this, the value is in the textfield, when i press the submit
form it say,
Failure writing parameter 'value' of component
remittance/Teller:dispensecashforquoteid: Expression
'transactionQuote.pickupQuoteID.id' for class
com.coinfling.web.pages.remittance.Teller is read-only.
What should i do ?
Kind Regards

By the way... the tapestry-dev list is for developers of tapestry. Messages
such as this should be posted on the tapestry-users list.

Never use ${...} in attributes.
Use t:value="transactionQuote.pickupQuoteID" instead and tapestry will
create two way property binding which it can then get() and set().
