I am trying to export repeat grid data to excel. To do this, I have provided a button which runs "MyCustomActivity" activity via clicking. The button is placed above the grid in the same layout. It also worth pointing out that I am utulizing an article as a guide to configure. According to the guide my "MyCustomActivity" activity contains two steps:
But after I had got an issue I have changed the 2nd step by Call Rule-Obj-Report-Definition.pzRDExportWrapper
But as you have already understood the solution doesn't work. I have checked the log files and found interesting error:
2017-04-11 21:08:27,992 [ WebContainer : 4] [OpenPortal] [ ] [ MyFW:01.01.02] (ctionWrapper._baseclass.Action) ERROR as1|172.22.254.110 bar - Activity 'MyCustomActivity' failed to execute; Failed to find a 'RULE-OBJ-ACTIVITY' with the name 'PZRESOLVECOPYFILTERS' that applies to 'COM-FW-MyFW-Work'.

If someone have any suggestions and share some, I will appreciate it. Thank you.
I wanted to provide a functionality of exporting retrieved works to a CSV file. The functionality should has a feature to choose fields to retrieve, all results should be in Ukrainian and be able to use any SearchFilter Pages and Report Definition rules.
At a User Portal I have two sections: the first section contains text fields and a Search button, and a section with a Repeat Grid to display results. The textfields are used to filter results and they use a page Org-Div-Work-SearchFilter.
I made a custom parser to csv. I created two activities and wrote some Java code. I should mention that I took some code from the pzPDExportWrapper.
The activities are:
Configurations of the ExportToCSV activity:
The Pages And Classes tab:
ReportDefinitionResults.pxResults denotes a type of a certain work.
FileName is a name of a generated file
Lets look through the steps:
1. Get an SearchFilte Page with a name from a Parameter with populated fields:
2. If SearchFilter is not Empty, call a Data Transform to convert SearchFilter's properties to Paramemer properties:
A fragment of the data Transform:
3. Gets an object of a Report Definition
4. Set parameters for the Report Definition
5. Invoke the Report Definition and save results to ReportDefinitionResults:
6. Invoke the ConvertResultsToCSV activity:
7. Delete the result page:
The overview of the ConvertResultsToCSV activity.
The Parameters tab if the ConvertResultsToCSV activity:
listSeperator is always a semicolon to separate fields.
Lets skim all the steps in the activity:
Get a separator according to localization. It is always a semicolon in Ukrainian, English and Russian. It is required to check in other languages.
The step contains Java code, which form a CSV string:
StringBuffer csvContent = new StringBuffer(); // a content of buffer
String pageListProp = tools.getParamValue("PageListProperty");
ClipboardProperty resultsProp = myStepPage.getProperty(pageListProp);
// fill the properties names list
java.util.List<String> propertiesNames = new java.util.LinkedList<String>(); // names of properties which values display in csv
String csvProps = tools.getParamValue("CSVProperties");
propertiesNames = java.util.Arrays.asList(csvProps.split(","));
// get user's colums names
java.util.List<String> columnsNames = new java.util.LinkedList<String>();
String CSVDisplayProps = tools.getParamValue("ColumnsNames");
if (!CSVDisplayProps.isEmpty()) {
columnsNames = java.util.Arrays.asList(CSVDisplayProps.split(","));
} else {
columnsNames.addAll(propertiesNames);
}
// add columns to csv file
Iterator columnsIter = columnsNames.iterator();
while (columnsIter.hasNext()) {
csvContent.append(columnsIter.next().toString());
if (columnsIter.hasNext()){
csvContent.append(listSeperator); // listSeperator - local variable
}
}
csvContent.append("\r");
for (int i = 1; i <= resultsProp.size(); i++) {
ClipboardPage propPage = resultsProp.getPageValue(i);
Iterator iterator = propertiesNames.iterator();
int propTypeIndex = 0;
while (iterator.hasNext()) {
ClipboardProperty clipProp = propPage.getIfPresent((iterator.next()).toString());
String propValue = "";
if(clipProp != null && !clipProp.isEmpty()) {
char propType = clipProp.getType();
propValue = clipProp.getStringValue();
if (propType == ImmutablePropertyInfo.TYPE_DATE) {
DateTimeUtils dtu = ThreadContainer.get().getDateTimeUtils();
long mills = dtu.parseDateString(propValue);
java.util.Date date = new Date(mills);
String sdate = dtu.formatDateTimeStamp(date);
propValue = dtu.formatDateTime(sdate, "dd.MM.yyyy", "", "");
}
else if (propType == ImmutablePropertyInfo.TYPE_DATETIME) {
DateTimeUtils dtu = ThreadContainer.get().getDateTimeUtils();
propValue = dtu.formatDateTime(propValue, "dd.MM.yyyy HH:mm", "", "");
}
else if ((propType == ImmutablePropertyInfo.TYPE_DECIMAL)) {
propValue = PRNumberFormat.format(localeCode,PRNumberFormat.DEFAULT_DECIMAL, false, null, new BigDecimal(propValue));
}
else if (propType == ImmutablePropertyInfo.TYPE_DOUBLE) {
propValue = PRNumberFormat.format(localeCode,PRNumberFormat.DEFAULT_DECIMAL, false, null, Double.parseDouble(propValue));
}
else if (propType == ImmutablePropertyInfo.TYPE_TEXT) {
propValue = clipProp.getLocalizedText();
}
else if (propType == ImmutablePropertyInfo.TYPE_INTEGER) {
Integer intPropValue = Integer.parseInt(propValue);
if (intPropValue < 0) {
propValue = new String();
}
}
}
if(propValue.contains(listSeperator)){
csvContent.append("\""+propValue+"\"");
} else {
csvContent.append(propValue);
}
if(iterator.hasNext()){
csvContent.append(listSeperator);
}
propTypeIndex++;
}
csvContent.append("\r");
}
CSVString = csvContent.toString();
5. This step forms and save a file in server's catalog tree
char sep = PRFile.separatorChar;
String exportPath= tools.getProperty("pxProcess.pxServiceExportPath").getStringValue();
DateTimeUtils dtu = ThreadContainer.get().getDateTimeUtils();
String fileNameParam = tools.getParamValue("FileName");
if(fileNameParam.equals("")){
fileNameParam = "RecordsToCSV";
}
//append a time stamp
Boolean appendTimeStamp = tools.getParamAsBoolean(ImmutablePropertyInfo.TYPE_TRUEFALSE,"AppendTimeStampToFileName");
FileName += fileNameParam;
if(appendTimeStamp) {
FileName += "_";
String currentDateTime = dtu.getCurrentTimeStamp();
currentDateTime = dtu.formatDateTime(currentDateTime, "HH-mm-ss_dd.MM.yyyy", "", "");
FileName += currentDateTime;
}
//append a file format
FileName += ".csv";
String strSQLfullPath = exportPath + sep + FileName;
PRFile f = new PRFile(strSQLfullPath);
PROutputStream stream = null;
PRWriter out = null;
try {
// Create file
stream = new PROutputStream(f);
out = new PRWriter(stream, "UTF-8");
// Bug with Excel reading a file starting with 'ID' as SYLK file. If CSV starts with ID, prepend an empty space.
if(CSVString.startsWith("ID")){
CSVString=" "+CSVString;
}
out.write(CSVString);
} catch (Exception e) {
oLog.error("Error writing csv file: " + e.getMessage());
} finally {
try {
// Close the output stream
out.close();
} catch (Exception e) {
oLog.error("Error of closing a file stream: " + e.getMessage());
}
}
Finally, we can post a button on some section or somewhere else and set up an Actions tab like this:
It also works fine inside "Refresh Section" action.
Thanks for reading.
