Typically used attributes
All attributes are
General attributes are
Binding to server side method that processes the events coming from this component.
The attribute value must be an expression.
| #{methodBinding} | Method binding |
Special binding to componet adapter object instance on server side.
The attribute value must be an expression.
| #{tobedefined} | Binding to IComponentAdapter instance |
Name of macro that is used for generating certain attributes of this component. Please pay attention: the value of this attribute is read one time for each control and cannot be changed afterwards.
The attribute value must not be changed once the component is created.
When a roundtrip is triggered then by default the curren user input is validated. This may lead to some change within the current user input field (e.g. is user just defines a date then the user might not yet have specified a correct date).
| false | Validations are executed (default) |
| true | Validations are not executed |
Baud rate of serial interface.
| 9600 | 9600 bit/s (default) |
| 4800 | 4800 bit/s |
| 2400 | 2400 bit/s |
Comment that can be asigned to any component. The comment is not operationally used.
| Any text | Any text |
If the serial device is sending events fast one after another then it may happen that the communication to the server is occupied while new serial events are received. By default the events are queued and then processed one by one. But: you may also define to send the events that are queued as one concatenated value - reducing the number of server roundtrips in theses scenarios as consequence.
| false | One actionListener call per serial event (default) |
| true | Concatenation may be done |
If defining CONCATENATE as true, then serial events ar queued when the communication to the server is just active. This duration (im milliseconds) describes when the queue is re-checked if can be sent to the server side as one concatenated value.
| 200 | 200 milliseconds |
If defining CONCATENATE as true, then this separator is used to separate the values from one another. By default no separator is used.
Configuration information that is attached to this component. This information is not functionally used by CaptainCasa, but may be used for any application specific purpose.
Data Bits

| 6 | 6 |
| 7 | 7 |
| 8 | 8 |
Parity
| None | None (default) |
| Even | Even |
| Odd | Odd |
Reference to an outside object that is the content behind the component. E.g. a field is representing a certain field of a database table: in this case you could define the value table;column. The reference plays a siginficant role within the attributemacro management.
The attribute value must not be changed once the component is created.
| ref | One reference |
| ref1;ref2 | Two references |
| ref1;ref2;ref3 | Three references |
Flag that indicated if this component is rendered at all. If set to false then the component is not rendered - there is no component data sent to the client.
The attribute value must be an expression.
| true | Component is rendered (default) |
| false | Component is not rendered |
Name of serial port.
| COM1 | COM1 (default) |
| COM2 | COM2 |
| COM3 | COM3 |
| COM4 | COM4 |
If set to true, then the roundtrip that is caused by the component does NOT clear the current statusbar content.
| false | Statusbar content is cleared. (default) |
| true | Statusbar content is kept. |
Stop Bits
| 1 | 1 |
| 1.5 | 1.5 |
| 2 | 2 |
By default messages from the serial interface are directly transferred to the server side. But you can also define a terminator-char-code: in this e case the messages are collected and appended until the terminator byte is received.
| No waiting for terminator byte (default) | |
| 13 | Wating for terminator code 13 (return) |
| ... | Any other decimal byte value |
