Class DataFieldValueTag

java.lang.Object
  javax.servlet.jsp.tagext.TagSupport
      com.taggercat.tags.DataFieldValueTag

All Implemented Interfaces:

java.io.Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class DataFieldValueTag
extends javax.servlet.jsp.tagext.TagSupport

This tag returns the value of the named field of the data source.
If an error has occurred (usually preventing a save) on this request/response cycle then the data from the request, and not from the model is used. Therefore, the user will not lose the data they just entered when errors occur. If there is no corresponding parameter on the request, then the value from the data source is used.
