Rettriving changed data from <hbj:TableView>

[Former Member]

Hi,

I have created a TableView, with 10 rows and 3 columns. All these fields are Input Fields, as set inside the TableViewBean. I am having problems retrieving the data from the JSP.

Here is the code for the TableViewBean model creation:

public void setModel(String[][] table) {
	String[] colNames = { "Username", "CostCentreGroup", "ReadWriteAccess" };
	model = new DefaultTableViewModel(table, colNames);
	
	model.setKeyColumn(1);
	
	TableColumn column = model.getColumn("Username");
	column.setTitle("Username");
	column.setType(TableColumnType.INPUT);
	
	column = model.getColumn("CostCentreGroup");
	column.setTitle("Cost Centre/Group"); 
	column.setType(TableColumnType.INPUT);
	
	column = model.getColumn("ReadWriteAccess");
	column.setTitle("Read/Write Access");
	column.setType(TableColumnType.INPUT);
	setExtab(table);
}

Here is the code for the JSP:

 <hbj:tableView
	id="myTableViewAdd"
	model="tvaBean.model"
	design="ALTERNATING"
	headerVisible="TRUE"
	footerVisible="TRUE"
	fillUpEmptyRows="TRUE"
	navigationMode="BYPAGE"
	selectionMode="NONE"
	visibleRowCount="10">
	 <% myTableViewAdd.useRowSelection(tvaBean.getOldTableView()); %>
</hbj:tableView>
<hbj:button
	id="add"
	text="Add Exception"
	onClick="onAddTableRows" />

Inside the Java, I have tried to retrieve the data that I enter on the screen, but I keep getting null pointer errors. When I retrieve the model from the bean, I get information, but just the old table, not the one that I had just modified on the screen.

I hope this is clearer than mud...

Cheers,

Hi Kevin,

Can you post what you did to get it to work? I'm having some issues with an iView that I'm developing using tableview as well...

Thanks a bunch

Hey Umair,

sorry for taking so long to get back... I was on vacation.

This is what I ended up doing.

JSP:

<hbj:tableView
	id="myTableView"
	model="tvBean.model"
	design="ALTERNATING"
	headerVisible="TRUE"
	footerVisible="TRUE"
	fillUpEmptyRows="FALSE"
	navigationMode="BYPAGE"
	selectionMode="MULTISELECT"
	visibleRowCount="10"
	visibleFirstRow="<%=tvBean.getVisibleFirstRow()%>"
	onNavigate="onDetailTableNavigate">
	<% myTableView.useRowSelection(tvBean.getOldTableView()); %>
	<% myTableView.setUserTypeCellRenderer(new TableViewCellRenderer()); %>
</hbj:tableView>

And in my bean:

public void setModel(String[][] table) {
	String[] colNames = { "Username", "CostCentreGroup", "ReadWriteAccess" };
	model = new DefaultTableViewModel(table, colNames);

	model.setKeyColumn(1);

	TableColumn column = model.getColumn("Username");
	column.setTitle("Username");
	column.setType(TableColumnType.TEXT);
	column.setEncode(true);
		
	column = model.getColumn("CostCentreGroup");
	column.setTitle("Cost Centre/Group"); 
	column.setType(TableColumnType.INPUT);
		
	column = model.getColumn("ReadWriteAccess");
	column.setTitle("Read/Write Access");
	column.setType(TableColumnType.USER);
	setExtab(table);
}

And lastly, when you want to update R/3 with values that you have changed in your tableView, add the following to your event:

//get table from session
TableView tv = (TableView) this.getComponentByName("myTableView");
updateTableContent(tv.getVisibleFirstRow(), tv.getVisibleLastRow());

and this method outside the event:

public void updateTableContent(int firstrow, int lastrow) {

	int lastrow_model = lastrow;
	if (lastrow_model > tvBean.getModel().getRowCount()) {
		lastrow_model = tvBean.getModel().getRowCount();
	}

	int loopcount = 0;
	for (int i = firstrow; i <= lastrow_model; i++) {
		loopcount = loopcount + 1;

		AbstractDataType data_box = context.getDataForComponentId("myTableView", "Username", loopcount);
		if (data_box != null)
			tvBean.getModel().setValueAt(data_box, i, 1);

		AbstractDataType data_mil = context.getDataForComponentId("myTableView", "CostCentreGroup", loopcount);
		if (data_mil != null)
			tvBean.getModel().setValueAt(data_mil, i, 2);

		AbstractDataType data_inf = context.getDataForComponentId("myTableView", "ReadWriteAccess", loopcount);
		if (data_inf != null)
			tvBean.getModel().setValueAt(data_inf, i, 3);
	}
}

Phew, I hope this helps.

Cheers,

Kevin

Kevin,

Can you please put the code for you BEAN in here too. Thanks, Angie.

Hi Angie,

This is the main code of the bean. The rest of it is just get and set methods.

public ReadWriteBean(String[][] header, String[][] body) {
	int numrows = 0;
	//+1 to the size so the number of columns includes the BSP App name column
	int size = header.length + 1;
	setRwSize(size);
	String[] colNames = new String[size];
	TableColumn column;

	for (int j = 0; j < size; j++) {
		colNames[j] = columnName;
	}

	model = new DefaultTableViewModel(body, colNames);

	model.setKeyColumn(1);

	column = model.getColumn(colNames[0]);
	column.setTitle("Your title");
	column.setType(TableColumnType.TEXT);
	column.setEncode(false);

	for (int j = 1; j < size; j++) {
		column = model.getColumn(colNames[j]);
		column.setTitle("more titles"));
		column.setType(TableColumnType.USER);
	}
	setModel(model);
	setAuth(body);
}

Hope this helps...
