FormBuilder 6.6 : How to Select multiple rows on a ReadonlyTable

smadduri

Hi ,

I have a ReadonlyTable with more than 15 rows .

My requirement is to select 3 - 5 rows on the tabe and delete the selected rows.

For this i used 'Multiple row Select' as shown in below screen To get checkbox multiselect rows at a time.

1.I have created delete invoke button action .

2.passing the dataitem as input to my Action class.

Iam also getting the selected row value in my action class when a single row is selected on the readonly table .

ISSUE :

My problem is if i select more than one row at a time , Iam getting only the row value even if i check two rows as in below screen.

have any encountered this problem for selecting multiple rows at a time on a table .

If any solution for this please help.

Regards

Sri

Hi Srini,

Yes, the concatenate adaptor will be executed every time you select a value in the read only table. On the “Special” tab of the concatenate data element, check the box “execute adaptor when input changes.” Then select the concatenate adaptor and assign the read only table as the input.

Here's how you do it: first you need to create another data element. For this new data element, assign a custom adaptor that concatenates the the values from the read only table. This adaptor would take the read only table as the input and output a concatenated string (e.g. "876;299"). Next, your action button should take the concatenated values from the new data element as the input, not the read only table directly. In your action code, you then need to parse out the concatenated values.

Here's code for an adaptor that concatenates multiple values:

public class MultiConcat extends DfService implements ISetValueAdaptor, IServiceAdaptor,

IDfService {

public Object execute(IAdaptorParameter[] params) throws AdaptorException {

StringBuilder buf = new StringBuilder();

try {

for (IAdaptorParameter param : params) {

if (param.getParameterInfo().getName().equals(INPUT_PARAM_VALUE)) {

String[] values = param.getValues();

int i = 0;

for (; i < values.length - 1; i++) {

buf.append(values[i]).append(separator);

}

buf.append(values[i]);

return buf.toString();

}

throw new RuntimeException("Missing parameter value");

} catch (final Exception e) {

throw new AdaptorException(ERR_FAILURE, e);

}

public void destroy() throws AdaptorException {

}

public void init(IAdaptorConfigurationconfig) throws AdaptorException {

final Properties params = config.getInitParams();

separator = params.getProperty(INIT_PARAM_SEPARATOR, separator);

}

public void setDocbaseName(String arg0) {

}

private static final String INIT_PARAM_SEPARATOR = "delimiter";

private static final String INPUT_PARAM_VALUE = "multivalue_field";

private static final String ERR_FAILURE = "The Adaptor failed to create the values.";

private String separator = ";";

}
