Hi,
I'm learning seam at the moment and wonder what I'm doing wrong.
Note:
Read a previous post with the same problem where the problem was solved by switching form
tomahawk datatable to standard datatable.
I have tried with both standard datatable and richfaces one, but the problem persists.
I'm trying to implement a simple search/select/edit/save use case with seam in order
to learn how to use some of the features (annotations, scopes and pageflow).
But in the search part of the flow, the first row is always outjected..
And I just started with Seam yesterday, so please point out any tips you have for me :-)
Backing bean:
| @Name("riskAddonBacking")
| @Scope( ScopeType.CONVERSATION)
| public class CountryRiskAddonBacking implements Serializable{
|
| /**
| *
| */
| private static final long serialVersionUID = 1L;
|
| @DataModel
| private List<CountryRiskAddonBean> searchResults;
|
| @DataModelSelection
| @Out(required=false)
| private CountryRiskAddonBean selectedItem;
|
| private String searchPattern;
|
| @Begin(pageflow="countryaddon")
| public void startPageFlow(){
|
| }
|
| public String performSearch(){
|
| int nbrHits = RandomUtils.nextInt()%10;
| List<CountryRiskAddonBean> tmpList = new
ArrayList<CountryRiskAddonBean>(nbrHits);
| for(int i=0; i<nbrHits; i++ ){
| CountryRiskAddonBean cab = new CountryRiskAddonBean();
| cab.setTicketNumber("RSK-" + (RandomUtils.nextInt()%10000) );
| cab.setCptyName("CptyXYZ");
| cab.setCountryOfRisk("SWE");
| tmpList.add( cab );
| }
| searchResults = tmpList;
|
| return null;
| }
|
| public String save(){
| System.out.println("SAAAAAAVVVVVVIIIIIIIIINNNNNNNNGGGGGGGG to db");
|
| return "";
| }
|
| public String getSearchPattern() {
| return searchPattern;
| }
|
| public void setSearchPattern(String searchPattern) {
| this.searchPattern = searchPattern;
| }

And OT, I get annoying error messages related to there not being a transaction, from the
ExceptionFilter. Is there a cure for this, read a post about this problem but it
didn't have a solution of how to get rid of it.
Cheers,
Mike
