I am developing a mobile application which allow the user to post the ad along with multiple images uploaded,I am trying to display that images for that particular ad in the bootstrap carousel , which doesn't allow me to pass the input parameter of the ad object.So how can i retrieve the images for that particular ad? https://modelshare.mendix.com/models/93c083d9-7cf9-4a83-b018-3bcf332d7a81/microflow-image
The widget is not currently set up to allow this input parameter. However, changing it is quite easy.
Here's the line you need to edit: change needsEntityContext="false" to needsEntityContext="true". This will cause the widget to expect to be placed inside of a data view, and your list microflow will expect that data view's object as a parameter.
If you haven't worked with custom widgets before, here's the quick and dirty way to edit a widget:
Go to your project directory, then the widgets folder
Find the bootstrap carousel widget
Rename from file extension from ".mpk" to ".zip"
Unzip the file
Open the BootstrapCarousel folder to find BootstrapCarousel.xml
Open the file, edit as above and save your changes
Re-zip the widget:
Selecting the BootstrapCarousel folder and package.xml
Right-clicking and select send to -> Compressed (zipped) folder
Rename the zip file back to the original mpk extension
Delete the remaining unzipped folders/files
In the modeler, press F4 to re-sync with the file system and force it to read your changes
