[jira] Updated: (BEEHIVE-771) Accessing netui tag properties in tag development
[ http://issues.apache.org/jira/browse/BEEHIVE-771?page=all ]
Carlin Rogers updated BEEHIVE-771:
----------------------------------
type: Improvement (was: Test)
Description:
I am trying to develop a custom tag based on the netui textbox. The syntax of the tag definision is the same and the ony difference is the datasource.
<bjeff:textBoxi dataSource="container.item.modul.tips.field" style="width:410px;" maxlength="100"/>
The purpose of the tag is to enable/dissable a info. button next to the text box.
Her is my custom tag code
public class TextBoxiTag extends TextBox {
private Field field;
/**
* @see org.apache.beehive.netui.tags.AbstractClassicTag#getTagName()
*/
public String getTagName() {
return "TextBoxi";
}
/**
* @see javax.servlet.jsp.tagext.BodyTagSupport#doEndTag()
*/
public int doEndTag() throws JspException {
// Finn referanse til actionForm
StringBuilderRenderAppender results = new StringBuilderRenderAppender(new StringBuilder());
ExpressionEvaluator ee = ExpressionEvaluatorFactory.getInstance();
ExpressionHandling eh = new ExpressionHandling(this); // param: INetuiTag
BaseForm formularet = (BaseForm) eh.evaluateExpression(
"{actionForm}", "form", this.pageContext);
String scriptId = null;
// String dataSource = evaluateDataSource().toString();
String dataSource = "{" + this._dataSource + "}";
if (ee.containsExpression(dataSource)) {
Object object = eh.evaluateExpression(
dataSource, "element", this.pageContext);
if ((object == null) || (!(object instanceof Felt))) {
Logger logger = Logger.getInstance(this.getClass());
logger.warn(Bundle.getString("Tags_ContentExpressionNull", dataSource));
return BodyTagSupport.SKIP_PAGE;
}
this.field= (Field) object;
} else {
return BodyTagSupport.SKIP_PAGE;
}
if(hasErrors()) {
reportErrors();
localRelease();
return EVAL_PAGE;
}
String textObject = felt.getFeltVerdi() == null? "" : felt.getFeltVerdi();
if(textObject == null)
textObject = "";
results.append("<input type=");
results.append("\"text\"");
/////////////////////////////////////////////////
Some code here
/////////////////////////////////////////////////
String regexp = felt.getFeltValideringsuttrykk();
results.append(" onBlur=\"");
results.append(this.getOnBlurJavascript());
results.append("(this,'");
results.append(formularet.getFeilOverskrift());
results.append("<div>");
results.append(StrengUtil.fjernSuffix(felt.getElementTekst(), FeltUtil.OBLIGATORISK_SUFFIX));
results.append("</div>', '");
String feilmelding = felt.getElementFeilmeldingstekst();
if ((feilmelding == null) || (feilmelding.equalsIgnoreCase(BaseController.NULLTEKST))) {
feilmelding = "";
}
results.append(feilmelding);
results.append("', '");
results.append(this.getSisteParam());
results.append("');\"");
results.append("/>");
if(scriptId != null)
results.append(scriptId);
write(results.toString());
localRelease();
return EVAL_PAGE;
}
In the region "Some code here" I would like to retrive those attributes "maxlength", "style" which I passed through in the jsp tag. I used this.getValue("maxlength") did NOT retrive the value of maxlength. Have you any suggession how I can retrieve those values and put it into the textbox tag attribute using this.setMaxlength() and so on.
An other problem is binding the netui tag datasource variable properly. The value of the binded datasource in NOT updated with the new value.
