### What happened?
I have tag `Mod1.FDPRT.PAP2.Axis[3].Drive.NcToPlc.ActTorque`
`"Axis[3]"` its not an array, its name of plc tag, so i expext that
everything works okay, but seems like it is not parsed in
`AdsDataTypeTableEntry` during connecting, so it throws exception
`PlcRuntimeException: Couldn't find child with name 'Axis[2]' for type
'FB_PAP2_FDPRT'`
in this piece of code, when it succesfully come to `"Axis[3]"` in
`remainingAddressParts.get(0)`, in `adsDataTypeTableEntry.getChildren()` there
is no such child, so i made conclusion that it is missed during connection
fetching of `dataTypeTable`
```
// Go through all children looking for a matching one.
for (AdsDataTypeTableChildEntry child :
adsDataTypeTableEntry.getChildren()) {
if
(child.getPropertyName().equals(remainingAddressParts.get(0))) {
AdsDataTypeTableEntry childAdsDataTypeTableEntry =
dataTypeTable.get(child.getDataTypeName());
return resolveDirectAdsTagForSymbolicNameFromDataType(
remainingAddressParts.subList(1,
remainingAddressParts.size()),
currentGroup, currentOffset + child.getOffset(),
childAdsDataTypeTableEntry);
}
}
```
i made an app that will just do browse request and read all children in a
tree
and as soon as i can see that it contains many similar tags defined on my plc
```
var browseRequest = plcConnection.browseRequestBuilder()
.addQuery("browse", "")
.build();
var browseResponse = browseRequest.execute().get();
var browseItems = browseResponse.getValues("browse");
```
and as soon as my plc return this tag, i expect that read request will
succeed, but seems `readSymbolTableAndDatatypeTable` acts strange
P.S. or actually that can be a mistake of plcBrowserequest, why it returns
me Axis[*] structure in root of request
as i can see it also contains
| +-- Mod1.TSHLN.PAP2.Axis: [List]
debugged a little, here is content of it
Why list does not contain definition of structure?
and some of array content structure just thrown in root of Browse items list?
maybe thats why i just thought that its not an array but static tag name
defined by our plc developers
