Form re submission of/on Page Reload Errror

The property 'action-url-redirect' must be added to the liferay-portlet.xml file. This will not allow the form to be re submitted once the page is refreshed after a form submission is already done.


<action-url-redirect>true</action-url-redirect>

By default the property is false and thus the form resubmission occurs

XML Validation in Liferay

The property 'xml.validation.enabled' must be added to the Portal-ext.properties file.

If set false,

xml.validation.enabled=false

The xml files won't be validated inside the liferay. In some cases,where the xml,DTD ..etc files are kept external. This property can be used to avoid the validation errors.
