How to make fmt:formatDate work for form:input
Solution 1
You can't use a JSP tag in an attribute of another JSP tag. STore the result of the date formatting in a page attribute, and use this page attribute (as you would do with a variable in Java):
<fmt:formatDate value="transactions['${loopStatus.index}'].valueTransactionDate"
type="date"
pattern="yyyy-MM-dd"
var="theFormattedDate" />
<form:input type="text" path="..." value="${theFormattedDate}"/>
Solution 2
In the latest releases of the spring JSTL tags you can't use the attribute value into de tah form:input. If you try, you will get a value attribute is not valid for tag <form:input>
error.
In this case you must use a normal HTML input tag and put the path as the name of the input to trigger the binding to the Spring form like this
<fmt:formatDate var="fmtDate" value="${form.bean.dateProperty}" pattern="dd/MM/yyyy"/>
<input type="text" name="bean.dateProperty" value="${fmtDate}"/>
Ugly but works for me! ;)

I have a jstl loop and I want to format the date of a form:input. I have tried many permutations of some of the suggestions that I've fond online but I just cannot get it to work.. Can someone please have a look?
I've included the full loop for context but the problem lies in the last
<td></td>
block.<c:forEach items="${valueTransactionsModel.transactions}" var="transaction" varStatus="loopStatus"> <tr class="${loopStatus.index % 2 == 0 ? 'even' : 'odd'}"> <spring:message code="valueTransactions.transactionType" var="transactionTypeLbl" /> <tags:dropdown id="transactionTypeId${loopStatus.index}" path="transactions['${loopStatus.index}'].valueTransactionType.id" fieldName="${transactionTypeLbl}" classStyle="mandatory" items="${transactionTypes}" itemLabel="value"/> </tr> <tr class="${loopStatus.index % 2 == 0 ? 'even' : 'odd'}"> <spring:message code="valueTransactions.transactionAmount" var="valueTransactionAmountLbl${loopStatus.index}" /> <tags:input id="transactionAmountId${loopStatus.index}" path="transactions['${loopStatus.index}'].valueTransactionAmount" fieldName="valueTransactionAmountLbl${loopStatus.index}" maxlength="30" classStyle="mandatory" /> <spring:message code="valueTransactions.transactionDate" var="valueTransactionDateLbl${loopStatus.index}" /> <td> <form:input type="text" path="transactions['${loopStatus.index}'].valueTransactionDate" cssClass="mandatory" value="<fmt:formatDate value="transactions['${loopStatus.index}'].valueTransactionDate" type="date" pattern="yyyy-MM-dd"/>" /> </td> </tr> </c:forEach>
My most recent issue is:
JSPG0055E: Unable to create an xml attribute from name [transactions[] value [${loopStatus.index}]

HellishHeat almost 12 yearsThanks! That pretty much did it. I just had to reference the model in the value attribute value="${valueTransactionsModel.transactions[loopStatus.index].valueTransactionDate}"
