Hi,
I use a rich:scrollableDataTable with a binding to dynamically create the columns:
<rich:scrollableDataTable id="myTable"
binding="#{dynamicTableBean.dataTable}"
value="#{dynamicTableBean.items}" var="item" width="700"
height="400" rows="40" sortMode="single" />
<a4j:commandLink value="Update" reRender="myTable"
action="#{dynamicTableBean.rerenderTable}" />
public void rerenderTable() {
HtmlColumn col;
HtmlOutputText col_header;
HtmlOutputText col_content;
// Remove old columns
List<Object> list = dataTable.getChildren();
if (!list.isEmpty()) {
int size = list.size();
for (int i = 0; i < size; i++) {
list.remove(0);
}
}
for (String column : selectedColumns) {
// header
col_header = new HtmlOutputText();
col_header.setValue(column);
// content
col_content = new HtmlOutputText();
col_content.setValueBinding("value", createValueBinding("#{item."
+ column + "}"));
// column
col = new HtmlColumn();
col.getFacets().put("header", col_header);
col.getChildren().add(col_content);
col.setId(column);
dataTable.getChildren().add(col);
}
}
When I invoke the rerender method, table is correctly displayed for 2 seconds and then disappears. During this 2 seconds CPU is at 100% and I can't do anything. This code perfectly worked with a regular rich:datatable.
Does anyone knows a solution on this?
Thanks and cheers
