Presentation d'une table

Bonjour,

Pour ce probleme je ne sais pas trop comment m'y prendre...
J'ai une table comme ça :

Code:

---

1 2 3 4 5 6 7 8 9 10

*--------*---------*------------* |Chanp1 |Chanp2 |Chanp3 | *--------*---------*------------* |AA |1 |100 | |AA |2 |80 | |BB |1 |150 | |CC |1 |50 | |CC |2 | | |CC |3 |110 |

---

Et je recherche a avoir ça dans la page .jsf:

Code:

---

1 2 3 4 5 6 7

*--------*-----*-----*-----* |Chanp1 |1 |2 |3 | *--------*-----*-----*-----* |AA |100 |80 | | |BB |150 | | | |CC |50 | |110 |

---

Si quelqu'un a une petite piste, ça serait sympa.

Merci

Voila ce que j'ai essayé :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

public class Tab { private DataModel _columnHeaders; private DataModel _data;   public UnitCoeffTab(){ createHeader(); createData(); }   private void createHeader(){ List<ColumnHeader> headerList = new ArrayList<ColumnHeader>(); headerList.add(new ColumnHeader("Champs","100",false)); headerList.add(new ColumnHeader("1","80",false)); headerList.add(new ColumnHeader("2","80",false)); headerList.add(new ColumnHeader("3","80",false)); _columnHeaders = new ListDataModel(headerList); } private void createData(){ List<String[]> dataList = new ArrayList<String[]>(); dataList.add(new String[] {"Toto","100", "200", "300"}); dataList.add(new String[] {"Tata","130", "80", "800"}); dataList.add(new String[] {"titi","40", "70", "400"}); _data = new ListDataModel(dataList); } public DataModel getColumnHeaders() { return _columnHeaders; } public Object getColumnValue() { Object columnValue = null; if (_data.isRowAvailable() && _columnHeaders.isRowAvailable()) { columnValue = ((List)_data.getRowData()).get(_columnHeaders.getRowIndex()); } return columnValue; }   public DataModel get_data() { return _data; } }

---

La page:

Code:

---

1 2 3 4 5 6 7 8 9

<t:dataTable value="#{tab._data}" var="row"> <t:columns value="#{tab.columnHeaders}" var="column"> <f:facet name="header"> <h:outputText value="#{column.label}" style="width=#{column.width}"/> </f:facet> <h:outputText value="XXXX"/> </t:columns> </t:dataTable>

---

Obtient :

Code:

---

1 2 3 4 5 6 7

*--------*-----*-----*-----* |Champs |1 |2 |3 | *--------*-----*-----*-----* |XXX |XXX |XXX |XXX | |XXX |XXX |XXX |XXX | |XXX |XXX |XXX |XXX |

---

si je fais :

Code:

---

1 2 3 4 5 6 7 8 9

<t:dataTable value="#{tab._data}" var="row"> <t:columns value="#{tab.columnHeaders}" var="column"> <f:facet name="header"> <h:outputText value="#{column.label}" style="width=#{column.width}"/> </f:facet> <h:outputText value="#{row.columnValue}"/> </t:columns> </t:dataTable>

---

Obtient :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161

Merci d'avance.

Je ne suis peut'etre pas sur la bonne piste ???

D'après l'erreur,
<h:outputText value="#{row.columnValue}"/> attend un String et pas autre chose.
Il suffit de créer une fonction getColumnValueToString qui renvoit un String et d'écrire :
<h:outputText value="#{row.columnValueToString}"/>

Merci pour ta reponse.

J'ai exactement la meme erreur si je fais :

Code:

---

1 2 3 4

public String getValue(){ return "tructruc"; }

---

Je l'avais deja tester!!!!
par contre si je fait

Code:

---

1 2 3 4 5 6 7 8 9 10 11

<t:dataTable value="#{tab._data}" var="row"> <t:columns value="#{tab.columnHeaders}" var="column"> <f:facet name="header"> <h:outputText value="#{column.label}" style="width=#{column.width}"/> </f:facet> <h:outputText value="#{row}"/> </t:columns> </t:dataTable>   J'obtient un tableau qui contient par ligne les valeurs des tableaux. ce qui me semble normal.
