getting dropdown list values in attribute

I am trying to populate a datadropdownlist control with a list of values from a value assistance configured in composer. here's what I have tried.

I am getting bad id error now.

<dmfx:docbaseobject name="obj"/>
<dmfx:docbaseattribute object="obj" name="Country" attribute="country"/>
<td align="left" nowrap></td>

Please let me know what is wrong in this piece of jsp code. Should i add or remove anything or should i add something in java class? Please advice.

"...populate a datadropdownlist control with a list of values from a value assistance configured in composer"

- If you are defining the value assistance from composer, you dont have to customize your jsp to display the attribute dropdownlist. You should be able to use the out of box attributes component.

Johnny,

Can you please provide some example as i am very new to development.

This is the code i tried using earlier which does not display any values in dropdown.

<dmf:dataoptionlist>

<dmf:option datafield=" countrylist " labeldatafield=" countrylist "/>

</dmf:dataoptionlist>

</dmf:datadropdownlist>

No custom code is required. If you define the attribute in the Display configuration in Composer, the attribute will show up in Properties screen. Make sure you run data dictionary publishing job and restart your app server.

No this attribute is getting displayed in the import component, but now i need this attribute in a report component. To get this attribue here, i am using the code i had posted earlier. But it does not show any values in the dropdown, but a blank dropdown list.

If you are creating your own custom component, then you will need to populate the jsp control using component class that corresponds to your component. Read the WDK Development guide for more details.

I tried using the following code in 2 ways.both did not work, it shows only a empty dropdwon.

In JSP,

<dmf:datadropdownlist name="Country" tooltipnlsid="MSG_COUNTRY"></td>

<dmf:dataoptionlist>

<dmf:option datafield="countrylist"/>

</dmf:dataoptionlist>

</dmf:datadropdownlist>

In Java,

countryQuery="select country as countrylist from dm_dbo.reg_country_lang";

m_country= (DataDropDownList)getControl("Country",DataDropDownList.class);
m_country.getDataProvider().setDfSession(getDfSession());
m_country.getDataProvider().setQuery(countryQuery);
//m_country.getDataProvider().refresh();

Option ctry = new Option();
ctry.setValue("m_country");

I also tried following code in componenet,

IDfCollection col = null;

IDfQuery query = new DfQuery();

query.setDQL(countryQuery);

TableResultSet categoryResultSet = new TableResultSet(new String[] {

"country"

});

String str1 = null;

try {

col = query.execute(getDfSession(), 0);

for(int i = 0; col.next(); i++) {

str1 = col.getString("country");

categoryResultSet.add(new String[] {

str1

});

System.out.println("country values are"+categoryResultSet);

System.out.println("country values in string are"+str1);

}

catch(DfException e) {

e.printStackTrace();

}

finally {

try {

if(col != null)

col.close();

}

catch(DfException e) { }

}

m_country.getDataProvider().setScrollableResultSet(categoryResultSet);
