Hi devs,
I'm raising this email again because I don't know if this a
bug/limitation/correct behavior.
I also think that the problem is from a thread point of view, at least
by the crash that I have.
Knowing that a processing algorithm, as suggested by Germàn, can be
created with:
processing.createAlgorithmDialog("my_provider:my_algorithm", params)
within a plugin, if the algorithm **id** is passed as first argument,
QGIS is crashing, while it seems working on a standalone script in the
QGIS code editor.
Is this a limitation?
Cheers and thanks for any suggestion!

Hi all,
I've a set of custom processing scripts within a plugin (that is both
"normal" and processing provider plugin).
I'm trying to executing the dialog of these algorithm from one of the
main plugin file. I found the processing.createAlgorithmDialog [0], but
it is constantly crashing when I'm passing the instance of the algorithm:
my_alg = MyCustomAlg()
my_dialog = my_alg.createAlgorithmDialog(custom_dict)
## crash here
Thinking it was a problem of the threads I also tried to overwrite the
`flag` method in the algorithm by setting also
QgsProcessingAlgorithm.FlagNoThreading but with the same results.
I know I can run the processing algorithm with processing.run(....) but
I need to open the dialog pre-filled with custom parameters and to get
also some other outputs besides the standard ones (like the
QgsFeatureSink path)
Thanks for any suggestion
Cheers
Matteo
