linvaux opened a new issue, #6451:
URL: https://github.com/apache/jmeter/issues/6451
### Expected behavior
When parsing a .jmx file using JMeter's SaveService.loadTree, the
getFilename() method of org.apache.jmeter.config.CSVDataSet returns null
despite the fact that the filename property is correctly set and visible within
the internal propMap, the csvdataset file is: data.csv
java code:
```java
private List<String> findDatasetFiles(HashTree hashTree) {
List<String> datasetFiles = new ArrayList<>();
if (hashTree == null) {
return datasetFiles;
}
for (Object item : hashTree.keySet()) {
if (item instanceof org.apache.jmeter.config.CSVDataSet
csvDataSet) {
String filename = csvDataSet.getFilename();
if (StringUtils.isNotBlank(filename)) {
datasetFiles.add(filename);
}
}
// 递归搜索子树
HashTree subTree = hashTree.get(item);
if (subTree != null) {
datasetFiles.addAll(findDatasetFiles(subTree));
}
}
return datasetFiles;
}
```
jxm:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<jmeterTestPlan version="1.2" properties="5.0" jmeter="5.6.3">

```
### Actual behavior
I got a empty list, but this code could get filename:
```java
private List<String> findDatasetFiles(HashTree hashTree) {
List<String> datasetFiles = new ArrayList<>();
if (hashTree == null) {
return datasetFiles;
}
for (Object item : hashTree.keySet()) {
log.debug("Found config element: {}", item.getClass().getName());
if (item instanceof org.apache.jmeter.config.CSVDataSet
csvDataSet) {
JMeterProperty filenameProp =
csvDataSet.getPropertyOrNull("filename");
if (filenameProp != null) {
log.debug("Found CSVDataSet: {}",
filenameProp.getStringValue());
datasetFiles.add(filenameProp.getStringValue());
}
}
// 递归查找子树
HashTree subTree = hashTree.get(item);
if (subTree != null) {
datasetFiles.addAll(findDatasetFiles(subTree));
}
}
return datasetFiles;
}
```
### Steps to reproduce the problem
- Create a simple JMeter test plan containing at least one ThreadGroup with
a CSVDataSet.
- Set a valid filename for the CSVDataSet.
- Save the test plan as a .jmx file.
- Use the following code snippet to load and parse the .jmx file:
```java
SaveService.loadProperties();
HashTree hashTree = SaveService.loadTree(new File(savedFileName));
findDatasetFiles(HashTree hashTree);
```
