How to set dynamic pattern for text field

[archanwizardsqueen]

I want to show date in text field in jasper report. I've kept expression class of that text field as "java.util.Date" because while exporting that date in excel I want to retain "format cells-category as Date or Custom type" instead of General. So that user can change date format if he wants. I don't want to use "java.text.DateFormat" because of the same above given reason. But I want to pass my date format as parameter to report and use that in report.

like pattern = "$P{myDateFormat}"

myDateFormat can be anything dd-MMM-yyy, dd/MM/yy or just anything given in java

But problem is, pattern property of textField does not take expression. I saw one bug closed for jasper which had same requirement see link. But don't know why it's not working.

Also read of patternExpression but it's not present in ireport. 

Kindly tell me how to pass dynamic value to pattern.

I found the answer from jaspersoft support:-

we can use patternExpression but it's not available in lower versions of iReport IDE so you need to compile and deploy jasper externally.

<textFieldExpression class="java.util.Date"><![CDATA[$P{d8}]]></textFieldExpression>

<patternExpression><![CDATA[$P{userDateFormat}]]></patternExpression>
